it necessary that we should go each about his respective business without delay; so, after a perfunctory lunch at a tea-shop, we separated, and I did not see my colleague again until the day’s work was finished, and I turned into our chambers just before dinner-time.
Here I found Thorndyke seated at the table, and evidently full of business. A microscope stood close by, with a condenser throwing a spot of light on to a pinch of powder that had been sprinkled on to the slide; his collecting-box lay open before him, and he was engaged, rather mysteriously, in squeezing a thick white cement from a tube on to three little pieces of moulding-wax.
“Useful stuff, this Fortafix,” he remarked; “it makes excellent casts, and saves the trouble and mess of mixing plaster, which is a consideration for small work like this. By the way, if you want to know what was on that poor girl’s pillow, just take a peep through the microscope. It is rather a pretty specimen.”
I stepped across, and applied my eye to the instrument. The specimen was, indeed, pretty in more than a technical sense. Mingled with crystalline grains of quartz, glassy spicules, and water-worn fragments of coral, were a number of lovely little shells, some of the texture of fine porcelain, others like blown Venetian glass.
“These are Foraminifera!” I exclaimed.
“Yes.”
“Then it is not silver sand, after all?”
“Certainly not.”
“But what is it, then?”
Thorndyke smiled. “It is a message to us from the deep sea, Jervis; from the floor of the Eastern Mediterranean.”
“And can you read the message?”
“I think I can,” he replied, “but I shall know soon, I hope.”
I looked down the microscope again, and wondered what message these tiny shells had conveyed to my friend. Deep-sea sand on a dead woman’s pillow! What could be more incongruous? What possible connection could there be between this sordid crime in the east of London and the deep bed of the “tideless sea”?
Meanwhile Thorndyke squeezed out more cement on to the three little pieces of moulding-wax (which I suspected to be the objects that I had seen him wrapping up with such care in the hall of the Goldsteins’ house); then, laying one of them down on a glass slide, with its cemented side uppermost, he stood the other two upright on either side of it. Finally he squeezed out a fresh load of the thick cement, apparently to bind the three objects together, and carried the slide very carefully to a cupboard, where he deposited it, together with the envelope containing the sand and the slide from the stage of the microscope.
He was just locking the cupboard when a sharp rat-tat on our knocker sent him hurriedly to the door. A messenger-boy, standing on the threshold, held out a dirty envelope.
“Mr. Goldstein kept me a awful long time, sir,” said he; “I haven’t been a-loitering.”
Thorndyke took the envelope over to the gas-light, and, opening it, drew forth a sheet of paper, which he scanned quickly and almost eagerly; and, though his face remained as inscrutable as a mask of stone, I felt a conviction that the paper had told him something that he wished to know.
The boy having been sent on his way rejoicing, Thorndyke turned to the bookshelves, along which he ran his eye thoughtfully until it alighted on a shabbily-bound volume near one end. This he reached down, and as he laid it open on the table, I glanced at it, and was surprised to observe that it was a bi-lingual work, the opposite pages being apparently in Russian and Hebrew.
“The Old Testament in Russian and Yiddish,” he remarked, noting my surprise. “I am going to get Polton to photograph a couple of specimen pages—is that the postman or a visitor?”
It turned out to be the postman, and as Thorndyke extracted from the letter-box a blue official envelope, he glanced significantly at me.
“This answers your question, I think, Jervis,” said he. “Yes; coroner’s subpoena and a very civil letter: ‘sorry to trouble you, but I had no choice under the circumstances’—of course he hadn’t—‘Dr. Davidson has arranged to make the autopsy tomorrow at 4 p.m., and I should be glad if you could be present. The mortuary is in Barker Street, next to the school.’ Well, we must go, I suppose, though Davidson will probably resent it.” He took up the Testament, and went off with it to the laboratory.
We lunched at our chambers on the following day, and, after the meal, drew up our chairs to the fire and lit our pipes. Thorndyke was evidently preoccupied, for he laid his open notebook on his knee, and, gazing meditatively into the fire, made occasional entries with his pencil as though he were arranging the points of an argument. Assuming that the Aldgate murder was the subject of his cogitations, I ventured to ask:
“Have you any material evidence to offer the coroner?”
He closed his notebook and put it away. “The evidence that I have,” he said, “is material and important; but it is disjointed and rather inconclusive. If I can join it up into a coherent whole, as I hope to do before I reach the court, it will be very important indeed—but here is my invaluable familiar, with the instruments of research.” He turned with a smile towards Polton, who had just entered the room, and master and man exchanged a friendly glance of mutual appreciation. The relations of Thorndyke and his assistant were a constant delight to me: on the one side, service, loyal and whole-hearted; on the other, frank and full recognition.
“I should think those will do, sir,” said Polton, handing his principal a small cardboard box such as playing-cards are carried in. Thorndyke pulled off the lid, and I then saw that the box was fitted internally with grooves for plates, and contained two mounted photographs. The latter were very singular productions indeed; they were copies each of a page of the Testament, one Russian and the other Yiddish; but the lettering appeared white on a black ground, of which it occupied only quite a small space in the middle, leaving a broad black margin. Each photograph was mounted on a stiff card, and each card had a duplicate photograph pasted on the back.
Thorndyke exhibited them to me with a provoking smile, holding them daintily by their edges, before he slid them back into the grooves of their box.
“We are making a little digression into philology, you see,” he remarked, as he pocketed the box. “But we must be off now, or we shall keep Davidson waiting. Thank you, Polton.”
The District Railway carried us swiftly eastward, and we emerged from Aldgate Station a full half-hour before we were due. Nevertheless, Thorndyke stepped out briskly, but instead of making directly for the mortuary, he strayed off unaccountably into Mansell Street, scanning the numbers of the houses as he went. A row of old houses, picturesque but grimy, on our right seemed specially to attract him, and he slowed down as we approached them.
“There is a quaint survival, Jervis,” he remarked, pointing to a crudely painted, wooden effigy of an Indian standing on a bracket at the door of a small old-fashioned tobacconist’s shop. We halted to look at the little image, and at that moment the side door opened, and a woman came out on to the doorstop, where she stood gazing up and down the street.
Thorndyke immediately crossed the pavement, and addressed her, apparently with some question, for I heard her answer presently: “A quarter-past six is his time, sir, and he is generally punctual to the minute.”
“Thank you,” said Thorndyke; “I’ll bear that in mind;” and, lifting his hat, he walked on briskly, turning presently up a side-street which brought
