The fourth man had not moved from his original position.

"I thought you were officers, blimy if I didn't, from the way you talked," said the first man. "Just a blinking Tommy and a blinking Poilu!"

"Monsieur," said the Frenchman, and there was a challenge in his voice, "I never forget a face."

"Nor I," said the third man quietly. "Nor other things; things that happened a bit back—after they put the draft into England, but before they called up the older classes. I don't know just how they worked it over here—that is, how some of them kept out of it as long as they did."

"Godam!" snarled the Frenchman. "Monsieur, you go too far! And—monsieur appears to have a sense of humour peculiarly his own—perhaps monsieur will be good enough to explain what he is laughing at?"

"With pleasure," said the third man calmly. "I was laughing at the recollection of a night, not like this one, though there's a certain analogy to it for all that, when an attack was made on—a strong box in a West End residence in London. Lord Seeton's, to be precise."

The first man stirred. He seemed to be groping around him where he sat.

"Foolish days! Perverted patriotism!" said the third man. "The family jewels, the hereditary treasures, gathered together to be offered on the altar of England's need! Fancy! But it was being done, you know. Rather! Only in this case the papers got hold of it and played it up a bit as a wonderful example, and that's how three men, none of whom had anything to do with the others, got hold of it too—no, I'm wrong there. Lord Seeton's valet naturally had inside information."

"Blimy!" rasped the first man suddenly. "A copper in khaki! That's what! A bloody, sneaking swine!"

It was inky black in the thicket. The third man's voice cut through the blackness like a knife.
