Trent shook his head. “We can’t build anything on that last consideration. I’ve gone into the subject with people who know. I shouldn’t wonder,” he added, “if the traditional notions about loss of temperature and rigour after death had occasionally brought an innocent man to the gallows, or near it. Dr. Stock has them all, I feel sure; most general practitioners of the older generation have. That Dr. Stock will make an ass of himself at the inquest, is almost as certain as that tomorrow’s sun will rise. I’ve seen him. He will say the body must have been dead about so long, because of the degree of coldness and _rigor mortis_. I can see him nosing it all out in some textbook that was out of date when he was a student. Listen, Murch, and I will tell you some facts which will be a great hindrance to you in your professional career. There are many things that may hasten or retard the cooling of the body. This one was lying in the long dewy grass on the shady side of the shed. As for rigidity, if Manderson died in a struggle, or labouring under sudden emotion, his corpse might stiffen practically instantaneously; there are dozens of cases noted, particularly in cases of injury to the skull, like this one. On the other hand, the stiffening might not have begun until eight or ten hours after death. You can’t hang anybody on _rigor mortis_ nowadays, inspector, much as you may resent the limitation. No, what we _can_ say is this. If he had been shot after the hour at which the world begins to get up and go about its business, it would have been heard, and very likely seen too. In fact, we must reason, to begin with, at any rate, on the assumption that he wasn’t shot at a time when people might be awake; it isn’t done in these parts. Put that time at 6.30 a.m. Manderson went up to bed at 11 p.m., and Martin sat up till 12.30. Assuming that he went to sleep at once on turning in, that leaves us something like six hours for the crime to be committed in; and that is a long time. But whenever it took place, I wish you would suggest a reason why Manderson, who was a fairly late riser, was up and dressed at or before 6.30; and why neither Martin, who sleeps lightly, nor Bunner, nor his wife heard him moving about, or letting himself out of the house. He must have been careful. He must have crept about like a cat. Do you feel as I do, Murch, about all this; that it is very, very strange and baffling?” “That’s how it looks,” agreed the inspector. “And now,” said Trent, rising to his feet, “I’ll leave you to your meditations, and take a look at the bedrooms. Perhaps the explanation of all this will suddenly burst upon you while I am poking about up there. But,” concluded Trent in a voice of sudden exasperation, turning round in the doorway, “if you can tell me at any time, how under the sun a man who put on all those clothes could forget to put in his teeth, you may kick me from here to the nearest lunatic asylum, and hand me over as an incipient dement.”
