“Hopeless, Watson, hopeless.”
“Why?”
“How does Cayley know that it is Mark who has shot Robert, and not the other way round?”
“Oh!” said Bill, rather upset. “Yes.” He thought for a moment, “All right. Say that Cayley has gone into the room first, and seen Robert on the ground.”
“Well?”
“Well, there you are.”
“And what does he say to Mark? That it’s a fine afternoon; and could he lend him a pocket-handkerchief? Or does he ask him what’s happened?”
“Well, of course, I suppose he asks what happened,” said Bill reluctantly.
“And what does Mark say?”
“Explains that the revolver went off accidentally during a struggle.”
