“Yes,” he said in answer to French’s question, “we held a post-mortem, Doctor Wilbraham and I, and we found the cause of death. Those injuries to the face and forehead were all inflicted after death. They were sufficient to cause death, but they did not do so. The cause of death was a heavy blow on the back of the head with some soft, yielding instrument. The skull was fractured, but the skin, though contused, was unbroken. Something like a sandbag was probably used. The man was struck first and killed, and then his features were destroyed with some heavy implement such as a hammer.” “That’s suggestive, isn’t it?” French commented. “You mean that the features were obliterated after death to conceal the man’s identity?” “No, I didn’t mean that, though of course it is true. What I meant was that the man was murdered in some place where blood would have been noticed, had it fallen. He was killed, not with a sharp-edged instrument, though one was available, but with a blunt one, lest bleeding should have ensued. Then when death had occurred the sharp-edged instrument was used and the face disfigured. I am right about the bleeding, am I not?” “Oh, yes. A dead body does not bleed, or at least not much. But I do not say that you could inflict all those injuries without leaving some bloodstains.” “No doubt, but still I think my deduction holds. There were traces of blood in the crate, but only slight. What age was the man, do you think, Doctor?” “Impossible to say exactly, but probably middle-aged: thirty-five to fifty-five.” “Any physical peculiarities?” “I had better show you my report. It will give you all I know. In fact, you can keep this copy.” French ran his eyes over the document, noting the points which might be valuable. The body was that of a middle-aged man five feet ten inches high, fairly broad and well built, and weighing thirteen stone. The injuries to the head and face were such that recognition from the features would be impossible. There was only one physical peculiarity which might assist identification—a small triangular birthmark on the back of the left arm. The report then gave technical details of the injuries and the condition the body was in when found, with the conclusion that death had probably occurred some thirty-five to forty days earlier. French smiled ruefully when he had finished reading. “There’s not overmuch to go on, is there?” he remarked. “I suppose nothing further is likely to come out at the inquest?” “Unless some one that we don’t know of comes forward with information, nothing,” the sergeant answered. “We have made all the enquiries that we could think of.” “As far as I am concerned,” Dr. Crowth declared, “I don’t see that you have anything to go on at all. I shouldn’t care for your job, Inspector. How on earth will you start trying to clear up this puzzle? To me it seems absolutely insoluble.”
