Dr. Thorndyke Omnibus Vol 1 Read online

  "This system of marking with reference numbers," said Mr. Singleton, "is better than your method of squares, because the numbers are only placed at points which are important for comparison, whereas your squares or the intersections of the lines fall arbitrarily on important or unimportant points according to chance. Besides, we can't let you mark our original, you know, though, of course, we can give you a photograph, which will do as well."

  "I was going to ask you to let me take a photograph presently," said Thorndyke.

  "Certainly," replied Mr. Singleton, "if you would rather have one of your own taking. I know you don't care to take anything on trust. And now I must get on with my work, if you will excuse me. Inspector Johnson will give you any assistance you may require."

  "And see that I don't pocket the original," added Thorndyke, with a smile at the inspector who had shown us in.

  "Oh, I'll see to that," said the latter, grinning; and, as Mr. Singleton returned to his table, Thorndyke unlocked the microscope case and drew forth the instrument.

  "What, are you going to put it under the microscope?" exclaimed Mr. Singleton, looking round with a broad smile.

  "Must do something for my fee, you know," replied Thorndyke, as he set up the microscope and screwed on two extra objectives to the triple nose-piece.

  "You observe that there is no deception," he added to the inspector, as he took the paper from Mr. Singleton's table and placed it between two slips of glass.

  "I'm watching you, sir," replied the officer, with a chuckle; and he did watch, with close attention and great interest, while Thorndyke laid the glass slips on the microscope stage and proceeded to focus.

  I also watched, and was a good deal exercised in my mind by my colleague's proceedings. After a preliminary glance with the six-inch glass, he swung round the nose-piece to the half-inch objective and slipped in a more powerful eye-piece, and with this power he examined the blood-stains carefully, and then moved the thumb-print into the field of vision. After looking at this for some time with deep attention, he drew from the case a tiny spirit lamp which was evidently filled with an alcoholic solution of some sodium salt, for when he lit it I recognised the characteristic yellow sodium flame. Then he replaced one of the objectives by a spectroscopic attachment, and having placed the little lamp close to the microscope mirror, adjusted the spectroscope. Evidently my friend was fixing the position of the "D" line (or sodium line) in the spectrum.

  Having completed the adjustments, he now examined afresh the blood-smears and the thumb-print, both by transmitted and reflected light, and I observed him hurriedly draw one or two diagrams in his notebook. Then he replaced the spectroscope and lamp in the case and brought forth the micrometer—a slip of rather thin glass about three inches by one and a half—which he laid over the thumb-print in the place of the upper plate of glass.

  Having secured it in position by the clips, he moved it about, comparing its appearance with that of the lines on the large photograph, which he held in his hand. After a considerable amount of adjustment and readjustment, he appeared to be satisfied, for he remarked to me—

  "I think I have got the lines in the same position as they are on our print, so, with Inspector Johnson's assistance, we will take a photograph which we can examine at our leisure."

  He extracted the camera—a quarter-plate instrument—from its case and opened it. Then, having swung the microscope on its stand into a horizontal position, he produced from the camera case a slab of mahogany with three brass feet, on which he placed the camera, and which brought the latter to a level with the eye-piece of the microscope.

  The front of the camera was fitted with a short sleeve of thin black leather, and into this the eye-piece end of the microscope was now passed, the sleeve being secured round the barrel of the microscope by a stout indiarubber band, thus producing a completely light-tight connection.

  Everything was now ready for taking the photograph. The light from the window having been concentrated on the thumb-print by means of a condenser, Thorndyke proceeded to focus the image on the ground-glass screen with extreme care and then, slipping a small leather cap over the objective, introduced the dark slide and drew out the shutter.

  "I will ask you to sit down and remain quite still while I make the exposure," he said to me and the inspector. "A very little vibration is enough to destroy the sharpness of the image."

  We seated ourselves accordingly, and Thorndyke then removed the cap, standing motionless, watch in hand, while he exposed the first plate.

  "We may as well take a second, in case this should not turn out quite perfect," he said, as he replaced the cap and closed the shutter.

  He reversed the dark slide and made another exposure in the same way, and then, having removed the micrometer and replaced it by a slip of plain glass, he made two more exposures.

  "There are two plates left," he remarked, as he drew out the second dark slide. "I think I will take a record of the blood-stain on them."

  He accordingly made two more exposures—one of the larger blood-stain and one of the smaller smears.

  "There," said he, with an air of satisfaction, as he proceeded to pack up what the inspector described as his "box of tricks." "I think we have all the data that we can squeeze out of Scotland Yard, and I am very much obliged to you, Mr. Singleton, for giving so many facilities to your natural enemy, the counsel for the defence."

  "Not our natural enemies, doctor," protested Mr. Singleton. "We work for a conviction, of course, but we don't throw obstacles in the way of the defence. You know that perfectly well."

  "Of course I do, my dear sir," replied Thorndyke, shaking the official by the hand. "Haven't I benefited by your help a score of times? But I am greatly obliged all the same. Good-bye."

  "Good-bye, doctor. I wish you luck, though I fear you will find it 'no go' this time."

  "We shall see," replied Thorndyke, and with a friendly wave of the hand to the inspector he caught up the two cases and led the way out of the building.

  IV. Confidences

  During our walk home my friend was unusually thoughtful and silent, and his face bore a look of concentration under which I thought I could detect, in spite of his habitually impassive expression, a certain suppressed excitement of a not entirely unpleasurable kind. I forbore, however, from making any remarks or asking questions, not only because I saw that he was preoccupied, but also because, from my knowledge of the man, I judged that he would consider it his duty to keep his own counsel and to make no unnecessary confidences even to me.

  On our arrival at his chambers he immediately handed over the camera to Polton with a few curt directions as to the development of the plates, and, lunch being already prepared, we sat down at the table without delay.

  We had proceeded with our meal in silence for some time when Thorndyke suddenly laid down his knife and fork and looked into my face with a smile of quiet amusement.

  "It has just been borne in upon me, Jervis," said he, "that you are the most companionable fellow in the world. You have the heaven-sent gift of silence."

  "If silence is the test of companionability," I answered, with a grin, "I think I can pay you a similar compliment in even more emphatic terms."

  He laughed cheerfully and rejoined—

  "You are pleased to be sarcastic, I observe; but I maintain my position. The capacity to preserve an opportune silence is the rarest and most precious of social accomplishments. Now, most men would have plied me with questions and babbled comments on my proceedings at Scotland Yard, whereas you have allowed me to sort out, without interruption, a mass of evidence while it is still fresh and impressive, to docket each item and stow it away in the pigeonholes of my brain. By the way, I have made a ridiculous oversight."

  "What is that?" I asked.

  "The 'Thumbograph.' I never ascertained whether the police have it or whether it is still in the possession of Mrs. Hornby."

  "Does it matter?" I inquired.

  "Not much; only I must
see it. And perhaps it will furnish an excellent pretext for you to call on Miss Gibson. As I am busy at the hospital this afternoon and Polton has his hands full, it would be a good plan for you to drop in at Endsley Gardens—that is the address, I think—and if you can see Miss Gibson, try to get a confidential chat with her, and extend your knowledge of the manners and customs of the three Messieurs Hornby. Put on your best bedside manner and keep your weather eye lifting. Find out everything you can as to the characters and habits of those three gentlemen, regardless of all scruples of delicacy. Everything is of importance to us, even to the names of their tailors."

  "And with regard to the 'Thumbograph'?"

  "Find out who has it, and, if it is still in Mrs. Hornby's possession, get her to lend it to us or—what might, perhaps, be better—get her permission to take a photograph of it."

  "It shall be done according to your word," said I. "I will furbish up my exterior, and this very afternoon make my first appearance in the character of Paul Pry."

  About an hour later I found myself upon the doorstep of Mr. Hornby's house in Endsley Gardens listening to the jangling of the bell that I had just set in motion.

  "Miss Gibson, sir?" repeated the parlourmaid in response to my question. "She was going out, but I am not sure whether she has gone yet. If you will step in, I will go and see."

  I followed her into the drawing-room, and, threading my way amongst the litter of small tables and miscellaneous furniture by which ladies nowadays convert their special domain into the semblance of a broker's shop, let go my anchor in the vicinity of the fireplace to await the parlourmaid's report.

  I had not long to wait, for in less than a minute Miss Gibson herself entered the room. She wore her hat and gloves, and I congratulated myself on my timely arrival.

  "I didn't expect to see you again so soon, Dr. Jervis," she said, holding out her hand with a frank and friendly manner, "but you are very welcome all the same. You have come to tell me something?"

  "On the contrary," I replied, "I have come to ask you something."

  "Well, that is better than nothing," she said, with a shade of disappointment. "Won't you sit down?"

  I seated myself with caution on a dwarf chair of scrofulous aspect, and opened my business without preamble.

  "Do you remember a thing called a 'Thumbograph'?"

  "Indeed I do," she replied with energy. "It was the cause of all this trouble."

  "Do you know if the police took possession of it?"

  "The detective took it to Scotland Yard that the finger-print experts might examine it and compare the two thumb-prints; and they wanted to keep it, but Mrs. Hornby was so distressed at the idea of its being used in evidence that they let her have it back. You see, they really had no further need of it, as they could take a print for themselves when they had Reuben in custody; in fact, he volunteered to have a print taken at once, as soon as he was arrested, and that was done."

  "So the 'Thumbograph' is now in Mrs. Hornby's possession?"

  "Yes, unless she has destroyed it. She spoke of doing so."

  "I hope she has not," said I, in some alarm, "for Dr. Thorndyke is extremely anxious, for some reason, to examine it."

  "Well, she will be down in a few minutes, and then we shall know. I told her you were here. Have you any idea what Dr. Thorndyke's reason is for wanting to see it?"

  "None whatever," I replied. "Dr. Thorndyke is as close as an oyster. He treats me as he treats every one else—he listens attentively, observes closely, and says nothing."

  "It doesn't sound very agreeable," mused Miss Gibson; "and yet he seemed very nice and sympathetic."

  "He is very nice and sympathetic," I retorted with some emphasis, "but he doesn't make himself agreeable by divulging his clients' secrets."

  "I suppose not; and I regard myself as very effectively snubbed," said she, smiling, but evidently somewhat piqued by my not very tactful observation.

  I was hastening to repair my error with apologies and self-accusations, when the door opened and an elderly lady entered the room. She was somewhat stout, amiable and placid of mien, and impressed me (to be entirely truthful) as looking rather foolish.

  "Here is Mrs. Hornby," said Miss Gibson, presenting me to her hostess; and she continued, "Dr. Jervis has come to ask about the 'Thumbograph.' You haven't destroyed it, I hope?"

  "No, my dear," replied Mrs. Hornby. "I have it in my little bureau. What did Dr. Jervis wish to know about it?"

  Seeing that she was terrified lest some new and dreadful surprise should be sprung upon her, I hastened to reassure her.

  "My colleague, Dr. Thorndyke, is anxious to examine it. He is directing your nephew's defence, you know."

  "Yes, yes," said Mrs. Hornby. "Juliet told me about him. She says he is a dear. Do you agree with her?"

  Here I caught Miss Gibson's eye, in which was a mischievous twinkle, and noted a little deeper pink in her cheeks.

  "Well," I answered dubiously, "I have never considered my colleague in the capacity of a dear, but I have a very high opinion of him in every respect."

  "That, no doubt, is the masculine equivalent," said Miss Gibson, recovering from the momentary embarrassment that Mrs. Hornby's artless repetition of her phrase had produced. "I think the feminine expression is more epigrammatic and comprehensive. But to return to the object of Dr. Jervis's visit. Would you let him have the 'Thumbograph,' aunt, to show to Dr. Thorndyke?"

  "Oh, my dear Juliet," replied Mrs. Hornby, "I would do anything—anything—to help our poor boy. I will never believe that he could be guilty of theft—common, vulgar theft. There has been some dreadful mistake—I am convinced there has—I told the detectives so. I assured them that Reuben could not have committed the robbery, and that they were totally mistaken in supposing him to be capable of such an action. But they would not listen to me, although I have known him since he was a little child, and ought to be able to judge, if anyone is. Diamonds, too! Now, I ask you, what could Reuben want with diamonds? and they were not even cut."

  Here Mrs. Hornby drew forth a lace-edged handkerchief and mopped her eyes.

  "I am sure Dr. Thorndyke will be very much interested to see this little book of yours," said I, with a view to stemming the tide of her reflections.

  "Oh, the 'Thumbograph,'" she replied. "Yes, I will let him have it with the greatest pleasure. I am so glad he wishes to see it; it makes one feel hopeful to know that he is taking so much interest in the case. Would you believe it, Dr. Jervis, those detective people actually wanted to keep it to bring up in evidence against the poor boy. My 'Thumbograph,' mind you. But I put my foot down there and they had to return it. I was resolved that they should not receive any assistance from me in their efforts to involve my nephew in this horrible affair."

  "Then, perhaps," said Miss Gibson, "you might give Dr. Jervis the 'Thumbograph' and he can hand it to Dr. Thorndyke."

  "Of course I will," said Mrs. Hornby; "instantly; and you need not return it, Dr. Jervis. When you have finished with it, fling it into the fire. I wish never to see it again."

  But I had been considering the matter, and had come to the conclusion that it would be highly indiscreet to take the book out of Mrs. Hornby's custody, and this I now proceeded to explain.

  "I have no idea," I said, "for what purpose Dr. Thorndyke wishes to examine the 'Thumbograph,' but it occurs to me that he may desire to put it in evidence, in which case it would be better that it should not go out of your possession for the present. He merely commissioned me to ask for your permission to take a photograph of it."

  "Oh, if he wants a photograph," said Mrs. Hornby, "I could get one done for him without any difficulty. My nephew Walter would take one for us, I am sure, if I asked him. He is so clever, you know—is he not, Juliet, dear?"

  "Yes, aunt," replied Miss Gibson quickly, "but I expect Dr. Thorndyke would rather take the photograph himself."

  "I am sure he would," I agreed. "In fact, a photograph taken by another person would not be of much
use to him."

  "Ah," said Mrs. Hornby in a slightly injured tone, "you think Walter is just an ordinary amateur; but if I were to show you some of the photographs he has taken you would really be surprised. He is remarkably clever, I assure you."

  "Would you like us to bring the book to Dr. Thorndyke's chambers?" asked Miss Gibson. "That would save time and trouble."

  "It is excessively good of you—" I began.

  "Not at all. When shall we bring it? Would you like to have it this evening?"

  "We should very much," I replied. "My colleague could then examine it and decide what is to be done with it. But it is giving you so much trouble."

  "It is nothing of the kind," said Miss Gibson. "You would not mind coming with me this evening, would you, aunt?"

  "Certainly not, my dear," replied Mrs. Hornby, and she was about to enlarge on the subject when Miss Gibson rose and, looking at her watch, declared that she must start on her errand at once. I also rose to make my adieux, and she then remarked—

  "If you are walking in the same direction as I am, Dr. Jervis, we might arrange the time of our proposed visit as we go along."

  I was not slow to avail myself of this invitation, and a few seconds later we left the house together, leaving Mrs. Hornby smiling fatuously after us from the open door.

  "Will eight o'clock suit you, do you think?" Miss Gibson asked, as we walked up the street.

  "It will do excellently, I should say," I answered. "If anything should render the meeting impossible I will send you a telegram. I could wish that you were coming alone, as ours is to be a business conference."

  Miss Gibson laughed softly—and a very pleasant and musical laugh it was.

  "Yes," she agreed. "Dear Mrs. Hornby is a little diffuse and difficult to keep to one subject; but you must be indulgent to her little failings; you would be if you had experienced such kindness and generosity from her as I have."
