"Careful!" he said. "Gad!—I know one of 'em, anyhow. Van Koon, as I live!"

CHAPTER XXXII

THE CHILVERTON ANTI-CLIMAX

The chief allowed himself to take a quick searching glance at the two men he had indicated. He had already heard of Van Koon and of his sudden disappearance from the hotel after the chance encounter with Chilverton, and he now regarded him with professional interest.

"The tall man, you mean?" he asked.

"Just so," answered Allerdyke. "The other man I don't know. But that's
Van Koon. What's he here for, now? Is he in this, after all?"

The chief made no reply. He was furtively watching the two men, who had dropped into chairs at a vacant table beneath the shade of the trees and were talking to a waitress. Having taken a good look at Van Koon, he turned his attention to Van Koon's companion, a little, dapper man, smartly dressed in bright blue serge, and finished off with great care in all his appointments. He seemed to be approaching middle age; there were faint traces of grey in his pointed beard and upward-twisted moustaches; he carried his years, however, in very jaunty fashion, and his white Homburg hat, ornamented with a blue ribbon, was set at a rakish angle on the side of his close-cropped head. In his right eye he wore a gold-rimmed monocle; just then he was bringing it to bear on the waitress who stood between himself and his companion.

"You don't know the other man, either of you?" asked the chief suddenly.

Allerdyke shook his head, but Appleyard nodded.

"I know that chap by sight," he said. "I've seen him in the City—about Threadneedle Street—two or three times of late. He's always very smartly dressed—I took him for a foreigner of some sort."
