Anthony held up the bag in explanation. Bannister frowned—then stretched out his hand for it. Anthony walked to the bed and picked up several of the keys that had lain there.

“Have to see this gentleman,” exclaimed the Inspector—he tapped the visiting-card with the back of his finger-nail. “It’s just possible that we’ve got the threads of the affair in our hands at last.”

“Yes,” smiled Anthony, “just ‘on the cards’ as you might say. If he recommended Miss Delaney to visit the Coolwater Avenue Surgery, it could certainly be argued against him that he might have known when to find her there. But look here, Inspector,” he paused—looked at the keys in his hand—then back to the hand-bag that Bannister was still holding.

“Well?” said Bannister, invitingly. Anthony smiled again. “It’s like this, Inspector. Imagination is a skittish sort of filly to ride—I’m well aware. But it seems to me that the hand-bag, the visiting-card, and these keys tell us a lot.” He looked quizzically at Bannister.

“I’m listening,” said that gentleman with the same touch of tolerant cynicism that Mr. Bathurst had observed before. “What’s the big idea?”

“Were there any signs, Inspector, when we entered ‘Rest Harrow’ just now—that any forced entrance had been effected?” Bannister promptly shook his head. “Well, then,” proceeded Anthony, “how did the people who played high jinks in this bedroom—get in?” He went on without waiting for Bannister to answer. “They got in with these keys, Inspector! And in my opinion this hand-bag containing these keys and this visiting-card, was taken from Miss Delaney at Seabourne either just before her death or just after.”

Bannister rubbed his chin thoughtfully with the fingers of his left hand. “I think you’re right, Mr. Bathurst. If only we knew what the devils were looking for. Get on the track of that and we shall be two-thirds of the way towards a complete solution. Yes, Ross—what is it?”

“No luck, sir—out in the garden. The dust-bin is empty. All the refuse that was here when the people went away must have been burned.”

“I was afraid so,” replied the Inspector. “Come and look in here!”

As Ross obeyed the behest Anthony tried the doors of the other bedrooms. They were locked and when opened presented no appearance beyond the ordinary. He called Bannister’s attention to them.
