“Well, you seem to know your own mind about that,” Wendover said rather wonderingly. “I suppose you know best. But I’d have thought it worth trying.”

Sir Clinton made no reply, but led the way through the Maze to the car.

“We’ll call at the police-station on the road home, Squire, if you’ll run us round there. I’m expecting some more reports. And some men must come up here and search for anything left about—not that it really matters. By the way,” he added, casually, “I suppose you know who the murderer is by this time?”

Wendover could only express astonishment at the question.

“Well, you’ve had every chance,” was all that Sir Clinton would vouchsafe.

“If you know who he is, why don’t you arrest him at once?” Wendover demanded.

“There’s a big gap between knowing a thing and proving it,” said Sir Clinton, cautiously.

At the police-station the Chief Constable got out of the car and went in to interview his subordinates. In a minute or two he was back again, with some papers in his hands; and they drove on to the Grange.

“I’ve just time to ring up Ardsley before going upstairs,” he said, when they arrived; and he disappeared in the direction of the telephone. Wendover noticed that this time Sir Clinton closed the door of the room behind him, instead of leaving it ajar as he had done on the previous occasions; so that no sound came out during the conversation.

“I wonder what he’s up to with that confounded Jack-the-Ripper,” Wendover speculated uneasily, as he went upstairs to dress. “Well, perhaps he’ll tell me something after dinner.”
