"I thought you might have fitted it in already," said Mr. Murch. "Come, Mr. Trent, we're only at the beginning of our inquiries, but what do you say to this for a preliminary theory? There's a plan of burglary--say a couple of men in it and Martin squared. They know where the plate is, and all about the handy little bits of stuff in the drawing-room and elsewhere. They watch the house; see Manderson off to bed; Martin comes to shut the window, and leaves it ajar--accidentally on purpose. They wait till Martin goes to bed at twelve-thirty; then they just walk into the library, and begin to sample the whisky first thing. Now suppose Manderson isn't asleep, and suppose they make a noise opening the window, or however it might be. He hears it; thinks of burglars; gets up very quietly to see if anything's wrong; creeps down on them, perhaps, just as they're getting ready for work. They cut and run; he chases them down to the shed, and collars one; there's a fight; one of them loses his temper and his head, and makes a swinging job of it. Now, Mr. Trent, pick that to pieces." "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 fully, and is murdered within sight of his house early enough to be cold and stiff by ten in the morning."
