"I've never crossed the Pacific," he said, after apparently satisfying himself as to the exact nature of the unpleasant token, "but one of my hobbies is the collection of ivories. In my home—"

"21,097 Park Avenue," interrupted Theydon.

"Just so—four doors short of 211th Street. Well, sir, when you blow in there you'll see a roomful of curios. I'm not exactly a connoisseur, but I know enough to tell Japanese work from Chinese. This was made by a Jap. And that reminds me. You said last night that Wong Li Fu put you off your balance by a jiu jitsu trick and handed that husky detective some, too. Very few Chinks have ever even heard of jiu jitsu. I've a notion that a bunch of Japs is mixed up in this business."

"Surely not?"

"It's possible. You good people here are crazy in your treatment of the Japanese. You think they're civilized because they dress in good shape, and can put up a mighty spry imitation of Western ways. But they ain't. They're the greatest menace to Europe that has yet come up on the tape. Do you believe they want China to wake up and organize before they're ready to take hold? No, sir. Anyhow, that skull was carved by a Japanese artist, and a bully good one at that."

The two were standing near the fireplace of a square and spacious foyer. There were plenty of people in the place, some conversing with friends, others writing or doing business at the various bureaus. It chanced that Theydon faced the two swing doors which led to the street, and he was returning the bit of ivory to his pocket when, somewhat to his surprise, Furneaux entered.

The detective saw him, too—of that he was quite certain—but ignored him completely. After one sharp, comprehensive glance around, as though he were seeking some one who was not visible, the little man went to a desk, scribbled a note, handed it in at the inquiry office, walked swiftly in the direction of an anteroom and restaurant, and disappeared forthwith.

Theydon was puzzled by Furneaux's behavior, but was quick to perceive that if the latter had not wished to be left alone he would at least have made some sign of recognition.

A page approached Mr. Handyside.

"Note for you, sir," he said.
