The sergeant considered for a moment, and Captain Tremayne became conscious for the first time that morning that his pulses were throbbing. At last his dreadful suspense came to an end.

“No, sir. Captain Tremayne turned the corner, and was out of my sight, seeing that I didn’t go beyond the guardroom doorway.”

Sir Terence’s lips parted with a snap of impatience. “But you must have heard,” he insisted. “You must have heard his steps—whether they went upstairs or straight on.”

“I am afraid I didn’t take notice, sir.”

“But even without taking notice it seems impossible that you should not have heard the direction of his steps. Steps going up stairs sound quite differently from steps walking along the level. Try to think.”

The sergeant considered again. But the president interposed. The testiness which Sir Terence had been at no pains to conceal annoyed Sir Harry, and this insistence offended his sense of fair play.

“The witness has already said that the didn’t take notice. I am afraid it can serve no good purpose to compel him to strain his memory. The court could hardly rely upon his answer after what he has said already.”

“Very well,” said Sir Terence curtly. “We will pass on. After the body of Count Samoval had been removed from the courtyard, did Mullins, my butler, come to you?”

“Yes, Sir Terence.”

“What was his message? Please tell the court.”
