"Exactly. Either these bones are the remains of John Bellingham or they are not. There will be no doubt on the subject when all the bones are assembled--if ever they are. And the settlement of that question will probably throw light on the further question: Who deposited them in the places in which they were found? But to return to your observations: did you gather nothing from the other bones? From the complete state of the neck vertebrae, for instance?"
"Well, it did strike me as rather odd that the fellow should have gone to the trouble of separating the atlas from the skull. He must have been pretty handy with the scalpel to have done it as cleanly as he seems to have done; but I don't see why he should have gone about the business in the most inconvenient way."
"You notice the uniformity of method. He has separated the head from the spine, instead of cutting through the spine lower down, as most persons would have done: he removed the arms with the entire shoulder-girdle, instead of simply cutting them off at the shoulder-joints. Even in the thighs the same peculiarity appears; for in neither case was the knee-cap found with the thigh-bone, although it seems to have been searched for. Now the obvious way to divide the leg is to cut through the patellar ligament, leaving the knee-cap attached to the thigh. But in this case, the knee-cap appears to have been left attached to the shank. Can you explain why this person should have adopted this unusual and rather inconvenient method? Can you suggest a motive for this procedure, or can you think of any circumstances which might lead a person to adopt this method by preference?"
"It seems as if he wished, for some reason, to divide the body into definite anatomical regions."
Thorndyke chuckled. "You are not offering that suggestion as an explanation, are you? Because it would require more explaining than the original problem. And it is not even true. Anatomically speaking, the knee-cap appertains to the thigh rather than to the shank. It is a sesamoid bone belonging to the thigh muscles; yet in this case it has been left attached, apparently, to the shank. No, Berkeley, that cat won't jump. Our unknown operator was not preparing a skeleton as a museum specimen; he was dividing a body up into convenient-sized portions for the purpose of conveying them to various ponds. Now what circumstances might have led him to divide it in this peculiar manner?"
"I am afraid I have no suggestion to offer. Have you?"
Thorndyke suddenly lapsed into ambiguity. "I think," he said, "it is possible to conceive such circumstances, and so, probably, will you if you think it over."
