"Poor Vane," he said, looking round. "I'm afraid the excitement of this morning has been a bit too much for him. If we're going to get them round in time, perhaps you'd better ring up his scout and send him for a doctor."

"Yes," said Ernshaw, looking up from where he was kneeling by Vane. "I suppose that's about the best thing to do, since the crime which you have committed is unfortunately not one which warrants me in sending for a policeman as well."

"Crime, sir, what the devil do you mean?" cried Garthorne, springing to his feet.

"I mean," said Ernshaw slowly and without moving, "exactly what I say. I feel perfectly certain from what I know of Maxwell that this could not possibly have occurred unless he had been deliberately tempted to drink. Your motives, of course, are best known to yourself and to Him who will judge them."

"So that's it, is it?" said Garthorne, with a harsh laugh. "You think I made him drunk for some purpose of my own, a man that I've been friends with ever since we punched each other's heads as boys. Well, you've been a good chum to Maxwell, so for his sake I'll pass over that idiotic remark of yours, and tell you for your information that he had been drinking before I came into the room at all."

"It's a lie!" exclaimed Ernshaw, springing to his feet and going towards the bell. "Nothing on earth could make me believe that." And then he rang the bell.

"I'm not accustomed to being called a liar," said Garthorne very quietly, "without resenting it in practical form; but as you don't seem to be quite yourself, and as there is so much physical difference in my favour, I'll take the trouble to convince you that I am speaking the truth."

He went into the bedroom and brought out Vane's coffee-cup.

"Smell that," he said.
