"John Dene!"

"Yes, of Toronto," continued Van Helder, smiling and continuing to blow rings with apparent enjoyment. "He is staying at the Ritzton, too."

"London is full of visitors."

"My friend, we waste time. There is such a thing as over-caution. As I say you are ungeschickt. There was that affair of John Dene's lunch. Such things will not please those——" He shrugged his shoulders.

For fully a minute Naylor gazed at him quietly, searchingly.

"There was then the chocolates and the girl."

"I do not understand." Mr. Naylor looked across at him craftily.

"We waste time, I know. I will tell you. The secretary, you make your woman offer her chocolates at a tea-shop, and to go for a ride in a taxi. The chocolates——" He shrugged his shoulders expressively. "She refuses. You are clumsy."

The contemptuous insolence of his visitor seemed to impress Mr. Naylor. The look of suspicion in his eyes became less marked.

"How did you know?" he asked, still wary.
