copal medium, is still comparatively wet, in spite of the hot sun and the dry air.
Ay, said the doctor. So I am forced to the conclusion that the chill of the water produced early rigor.
I do not submit to force, said Wimsey. I prefer to believe that the man was killed about midnight. I do not believe in that painting. I do not think it is telling the truth. I know that it is absolutely impossible for Campbell to have been working here on that painting this morning.
Why so? inquired the Sergeant.
For the reasons I gave you before, said Wimsey. And theres another small point not very much in itself, but supporting the same conclusion. The whole thing looks and is meant to look as though Campbell had got up from his painting, stepped back to get a better view of his canvas, missed his footing and fallen down. But his palette and painting-knife were laid down on his stool. Now its far more likely that, if he were doing that, he would have kept his palette on his thumb and his knife or brush in his hand, ready to make any little extra touch that was required. I dont say he might not have laid them down. I would only say it would have looked more natural if we had found the palette beside the body and the knife half-way down the slope.
Ay, said Ross. Ive seen em dew that. Steppin back wi their eyes half-shut and then hoppin forward wi the brush as if they was throwin darts.
Wimsey nodded.
Its my theory, he said, that the murderer brought the body here this morning in Campbells own car. He was wearing Campbells soft hat and that foul plaid cloak of his so that anybody passing by might mistake him for Campbell. He had the body on the floor of the tonneau and on top of it he had a push-cycle, which has left tarry marks on the cushions. Tucked in over the whole lot he had this rug, which has tar-marks on it too. Then I think he dragged out the corpse, carried it up the sheep-track on his shoulders and tumbled it into the burn. Or possibly he left it lying on the top of the bank, covered with the rug. Then, still wearing Campbells hat and cloak, he sat down and faked the picture. When he had done enough to create the impression that Campbell had been here painting, he took off the cloak and hat, left the palette and knife on the seat and went away on his push-bike. Its a lonely spot, here. A man might easily commit a dozen murders, if he chose his time well.
Thats a verra interesting theory, said Dalziel.
You can test it, said Wimsey. If anybody saw Campbell this morning to speak to, or close enough to recognise his face, then, of course, its a wash-out. But if they only saw the hat and cloak, and especially if they noticed anything bulky in the back of the car with a rug over it, then the theory stands. Mind you, I dont say the bicycle is absolutely necessary to the theory, but its what I should have used in the murderers place. And if youll look at this smear of tar under the lens, I think youll see traces of the tread of a tyre.
Ill no say yere no richt, said Dalziel.
Very well, said Wimsey. Now lets see what our murderer has to do next. He flapped the map impressively, and the two policemen bent their heads over it with him.
Here he is, said Wimsey, with only a bicycle to help or hinder him, and hes got to establish some sort of an alibi. He may not have bothered about anything very complicated, but hed make haste to dissociate himself from this place as quickly as possible. And I dont fancy hed be anxious to show himself in Newton-Stewart or Creetown. Theres nowhere much for him to go northward it only takes him up into the hills round Larg and the Rhinns of Kells. He could go up to Glen Trool, but theres not much point in that; hed only have to come back the same way. He might, of course, follow the Cree back on the eastern bank as far as Minniegaff, avoiding
