"Have they found any considerable part of the body yet? I haven't been reading the papers myself. My little friend, Miss Oman, brought a great bundle of 'em for me to read, but I couldn't stand it; I pitched the whole boiling of 'em out of the window."
I thought I detected a slight twinkle in Thorndyke's eye, but he answered quite gravely: "I think I can give you the particulars from memory, though I won't guarantee the dates. The original discovery was made, apparently quite accidentally, at Sidcup on the fifteenth of July. It consisted of a complete left arm, minus the third finger and including the bones of the shoulder--the shoulder-blade and collar-bone. This discovery seems to have set the local population, especially the juvenile part of it, searching all the ponds and streams of the neighbourhood--"
"Cannibals!" interjected Mr. Bellingham.
"With the result that there was dredged up out of a pond near St. Mary Cray, in Kent, a right thigh-bone. There is a slight clue to identity in respect of this bone, since the head of it has a small patch of what is called 'eburnation'--that is a sort of porcelain-like polish that occurs on the parts of bones that form a joint when the natural covering of cartilage is destroyed by disease. It is produced by the unprotected surface of one bone grinding against the similarly unprotected surface of another."
"And how," Mr. Bellingham asked, "would that help the identification?"
"It would indicate," replied Thorndyke, "that the deceased had probably suffered from rheumatoid arthritis--what is commonly known as rheumatic gout--and he would probably have limped slightly and complained of some pain in the right hip."
"I am afraid that doesn't help us much," said Mr. Bellingham; "for, you see, John had a pretty pronounced limp from another cause, an old injury to his left ankle; and as to complaining of pain--well, he was a hardy old fellow and not much given to making complaints of any kind. But don't let me interrupt you."
"The next discovery," continued Thorndyke, "was made near Lee, by the police this time. They seem to have developed sudden activity in the matter, and in searching the neighbourhood of West Kent they dragged out of a pond near Lee the bones of a right foot. Now, if it had been the left instead of the right we might have had a clue, as I understand that your brother had fractured his left ankle, and there might have been some traces of the injury on the foot itself."
"Yes," said Mr. Bellingham, "I suppose there might. The injury was described as a Pott's fracture."
