He had stepped politely in, and by dint of cleverly keeping his finger on the hook in the half light, he carried on a one-sided conversation with himself long enough to get a good chance to look about.

There was an air of quiet and refinement about the apartment in the Recherche. It was darkened to give the little glowing electric bulbs in their silken shades a full chance to simulate right. The deep velvety carpets were noiseless to the foot, and the draperies, the pictures, the bronzes, all bespoke taste.

But the chief objects of interest to Craig were the little square green baize-covered tables on one of which lay neatly stacked a pile of gilt-edged cards and a mahogany box full of ivory chips of red, white and blue.

It was none of the old-time gambling places, like Danfield’s, with its steel door which Craig had once cut through with an oxyacetylene blowpipe in order to rescue a young spendthrift from himself.

Kennedy seemed perfectly well satisfied merely with a cursory view of the place, as he hung up the receiver and thanked the maid politely for allowing him to use it.

“This is up-to-date gambling in cleaned-up New York,” he remarked as we waited for the elevator to return for us. “And the worst of it all is that it gets the women as well as the men. Once they are caught in the net, they are the most powerful lure to men that the gamblers have yet devised.”

We rode down in silence, and as we went down the steps to the street, I noticed the man whom we had seen watching the place, lurking down at the lower corner. Kennedy quickened his pace and came up behind him.

“Why, Winters!” exclaimed Craig. “You here?”

“I might say the same to you,” grinned the detective not displeased evidently that our trail had crossed his. “I suppose you are looking for Schloss, too. He’s up in the Recherche a great deal, playing poker. I understand he owns an interest in the game up there.”

Kennedy nodded, but said nothing.
