“Someone has been over here,” said Thorndyke, but as this is an orchard, there is nothing remarkable in the fact. However, there is no fruit on the trees now, and the cloth looks fairly fresh. There are two kinds, you notice: a dark blue and a black and white mixture of some kind.”
“Corresponding, probably, to the coat and trousers,” I suggested.
“Possibly,” he agreed, taking from his pocket a couple of the little seed-envelopes of which he always carried a supply. Very delicately he picked the tiny wisps of cloth from the hooks and bestowed each kind in a separate envelope. Having pocketed these, he leaned over the fence and threw the light of his lamp along the narrow lane or alley that divided the orchard from the adjoining premises. It was ungravelled and covered with a growth of rank grass, which suggested that it was little frequented. But immediately below was a small patch of bare earth, and on this was a very distinct impression of a foot, covering several less distinct prints.
“Several people have been over here at different times,” I remarked.
“Yes,” Thorndyke agreed. “But that sharp foot print belongs to the last one over, and he is our concern. We had better not confuse the issues by getting over ourselves. We will mark the spot and explore from the other end.” He laid his handkerchief over the top of the fence and we then went back to the house.
“You are going to take a plaster cast, I suppose?” said I; and as he assented, I fetched the research-case from the drawing-room. Then we fixed the catch of the front-door latch and went out, drawing the door to after us.
We found the entrance to the alley about sixty yards from the gate, and entering it, walked slowly forwards, scanning the ground as we went. But the bright lamplight showed nothing more than the vague marks of trampling feet on the grass until we came to the spot marked by the handkerchief on the fence.
It is a pity,” I remarked, “that this footprint has obliterated the others.”
“On the other hand,” he replied, “this one, which is the one that interests us, is remarkably clear and characteristic: a circular heel and a rubber sole of a recognisable pattern mended with a patch of cement paste. It is a footprint that could be identified beyond a doubt.”
As he was speaking, he took from the research-case the water-bottle, plaster-tin, rubber mixing-bowl and spoon, and a piece of canvas with which to “reinforce” the cast. Rapidly, he mixed a bowlful—extra thick, so that it should set quickly and hard—dipped the canvas into it, poured the remainder into the footprint, and laid the canvas on it.
I will get you to stay here, Jervis,” said he, “until the plaster has set. I want to examine the body rather more thoroughly before the police arrive, particularly the back.”
“Why the back?” I asked.
“Did not the appearance of the body suggest to you the advisability of examining the back?” he asked, and then, without waiting for a reply, he went off, leaving the inspection-lamp with me.
His words gave me matter for profound thought during my short vigil. I recalled the appearance of the dead woman very vividly—indeed, I am not likely ever to forget it—and I strove to connect that appearance with his desire to examine the back of the corpse. But there seemed to be no connection at all. The visible injuries were in front, and I had seen nothing to suggest the existence of any others. From time to time I tested the condition of the plaster, impatient to rejoin my colleague but fearful of cracking the thin cast by raising it prematurely. At length the plaster seemed to be hard enough, and trusting to the strength of the canvas, I prised cautiously at the edge, when, to my relief, the brittle plate came up safely and I lifted it clear. Wrapping it carefully in some spare rag, I packed it in the research-case, and then, taking this and the lantern, made my way back to the house.
When I had let down the catch and closed the front door, I went to the drawing-room, where I found Thorndyke stooping over the dark stain at the threshold and scanning the floor as if in search of something. I re ported the completion of the cast and then asked him what he was looking for.
“I am looking for a button,” he replied. “There is one missing from the back; the one to which the collar was fastened.”
“Is it of any importance?” I asked.
“It is important to ascertain when and where it became detached,” he replied. “Let us have the inspection-lamp.”
I gave him the lamp, which he placed on the floor, turning it so that its beam of light travelled along the surface. Stooping to follow the light, I scrutinised the floor minutely but in vain.
“It may not be here at all,” said I; but at that moment the bright gleam, penetrating the darkness under a cabinet, struck a small object close to the wall. In a moment I had thrown myself prone on the carpet, and reaching under the cabinet, brought forth a largish mother-of-pearl button.
“You notice,” said Thorndyke, as he examined it, “that the cabinet is near the window, at the opposite end of the room to the couch. But we had better see that it is the right button.”
He walked slowly towards the couch, still stooping and searching the floor with the light. The corpse, I noticed, had been turned on its side, exposing the back and the displaced collar. Through the strained button-hole of the latter Thorndyke passed the button without difficulty.
“Yes,” he said, “that is where it came from. You will notice that there is a similar one in front. By the way,” he continued, bringing the lamp close to the surface of the grey serge dress, “I picked off one or two hairs—animal hairs; cat and dog they looked like. Here are one or two more. Will you hold the lamp while I take them off?”
“They are probably from some pets of hers,” I remarked, as he picked them off with his forceps and deposited them in one of the invaluable seed-envelopes. “Spinsters are a good deal addicted to pets, especially cats and dogs.”
“Possibly,” he replied. “But I could see none in front, where you would expect to find them, and there seem to be none on the carpet. Now let us replace the body as we found it and just have a look at our material before the police arrive. I expected them here before this.”
We turned the body back into its original position, and taking the research-case and the lamp, went into the dining-room. Here Thorndyke rapidly set up the little travelling microscope, and bringing forth the seed-envelopes, began to prepare slides from the contents of some while I prepared the others. There was time only for a very hasty examination, which Thorndyke made as soon as the specimens were mounted.
“The clothing,” he reported, with his eye at the microscope, “is woollen in both cases. Fairly good quality. The one a blue serge, apparently indigo dyed; the other a mixture of black and white, no other colour. Probably a fine tabby or a small shepherd’s plaid.”
“Serge coat and shepherd’s plaid trousers,” I suggested. “Now see what the hairs are.” I handed him the slide, on which I had roughly mounted the collection in oil of lavender, and he placed it on the stage.
“There are three different kinds of hairs here,” he reported, after a rapid inspection. “Some are obviously from a cat—a smoky Persian. Others are long, rather fine tawny hairs from a dog. Probably a Pekinese. But there are two that I can’t quite place. They look like monkey’s hairs, but they are a very unusual colour. There is a perceptible greenish tint, which is extremely uncommon in mammalian hairs. But I hear the taxi approaching. We need not be expansive to the local police as to what we have observed. This will probably be a case for the C.I.D.”
I went out into the hall and opened the door as Meade came up the path, followed by two men; and as the latter came into the light, I was astonished to recognise in one of them our old friend, Detective-Superintendent Miller, the other being, apparently, the station superintendent.
“We have kept Mr. Meade a long time,” said Miller, “but we knew you were here,
