“I have never heard such a nonsense before.“ says Lestrade. “If that isn’t clear, what could be clear? Here is a young man who learns suddenly that if a certain older man dies he will succeed to a fortune. What does he do? He says nothing to anyone, but he arranges that he shall go out on some pretext to see his client that night; he waits until the only other person in the house is in bed, and then in the solitude of a man’s room he murders him, burns his body in the wood-pile, and departs to a neighbouring hotel. The blood-stains in the room and also on the stick are very slight. It is probable that he imagined his crime to be a bloodless one, and hoped that if the body were consumed it would hide all traces of the method of his death — traces which for some reason must have pointed to him. Is all this not obvious?”

“You've got a point”
“Could have been another person”
“It's all too obvious”
