"The right spirit, Comrade Win—"

A report like a cannon in the room below interrupted him. It was merely a revolver shot, but in the confined space it was deafening. The bullet sang up into the sky.

"Never hit me!" said Psmith with dignified triumph.

The noise was succeeded by a shuffling of feet. Psmith grasped his stick more firmly. This was evidently the real attack. The revolver shot had been a mere demonstration of artillery to cover the infantry's advance.

Sure enough, the next moment a woolly head popped through the opening, and a pair of rolling eyes gleamed up at the old Etonian.

"Why, Sam!" said Psmith cordially, "this is well met! I remember you. Yes, indeed, I do. Wasn't you the feller with the open umbereller that I met one rainy morning on the Av-en-ue? What, are you coming up? Sam, I hate to do it, but—"

A yell rang out.

"What was that?" asked Billy Windsor over his shoulder.

"Your statement, Comrade Windsor, has been tested and proved correct."

By this time the affair had begun to draw a "gate." The noise of the revolver had proved a fine advertisement. The roof of the house next door began to fill up. Only a few of the occupants could get a clear view of the proceedings, for a large chimney-stack intervened. There was considerable speculation as to what was passing between Billy Windsor and Mr. Gooch. Psmith's share in the entertainment was more obvious. The early comers had seen his interview with Sam, and were relating it with gusto to their friends. Their attitude towards Psmith was that of a group of men watching a terrier at a rat-hole. They looked to him to provide entertainment for them, but they realised that the first move must be with the attackers. They were fair-minded men, and they did not expect Psmith to make any aggressive move.
