“This is a terribly serious thing, Mr Wimble,” he said sternly. “You are charging Mr Lisle with murder.”

“Terribly serious thing to take Mr Gartram’s life, sir.”

“If he did, my man—if he did. But it must be all a mistake.”

“I hope it is, sir, indeed.”

“If the police knew of this, it would be awkward for Mr Lisle.”

“Of course it would, sir.”

“But, my good man, you are taking the view that he is guilty. I tell you that it is impossible.”

“I hope it is, sir; but I’ve gone over it in my bed till I’m obliged to believe Mr Lisle did it; and I feel I couldn’t keep the secret any longer.”

“And so you came to me?”

“Yes, sir, as Mr Gartram’s business-man.”
