'Very well,' said Trent; 'just to oblige you, Murch, especially as I know you don't believe a word of it. First: no traces of any kind left by your burglar or burglars, and the window found fastened in the morning, according to Martin. Not much force in that, I allow. Next: nobody in the house hears anything of this stampede through the library, nor hears any shout from Manderson either inside the house or outside. Next: Manderson goes down without a word to anybody, though Bunner and Martin are both at hand. Next: did you ever hear, in your long experience, of a householder getting up in the night to pounce on burglars, who dressed himself fully, with underclothing, shirt; collar and tie, trousers, waistcoat and coat, socks and hard leather shoes; and who gave the finishing touches to a somewhat dandified toilet by doing his hair, and putting on his watch and chain? Personally, I call that over-dressing the part. The only decorative detail he seems to have forgotten is his teeth.'
The inspector leaned forward thinking, his large hands clasped before him. 'No,' he said at last. 'Of course there's no help in that theory. I rather expect we have some way to go before we find out why a man gets up before the servants are awake, dresses himself awry, and is murdered within sight of his house early enough to be 'cold and stiff by ten in the morning.'
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 I can see him nosing it all out in some textbook that was out of date when he was a student.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.
