“We’ll risk it,” said Mike.

Jellicoe giggled in the background; the drama in the atmosphere appealed to him. His was a simple and appreciative mind.

“Come on, you chaps,” cried Spiller suddenly.

There was an inward rush on the enemy’s part, but Mike had been watching. He grabbed Spiller by the shoulders and ran him back against the advancing crowd. For a moment the doorway was blocked, then the weight and impetus of Mike and Spiller prevailed, the enemy gave back, and Mike, stepping into the room again, slammed the door and locked it.

“A neat piece of work,” said Psmith approvingly, adjusting his tie at the looking-glass. “The preliminaries may now be considered over, the first shot has been fired. The dogs of war are now loose.”

A heavy body crashed against the door.

“They’ll have it down,” said Jellicoe.

“We must act, Comrade Jackson! Might I trouble you just to turn that key quietly, and the handle, and then to stand by for the next attack.”

There was a scrambling of feet in the passage outside, and then a repetition of the onslaught on the door. This time, however, the door, instead of resisting, swung open, and the human battering-ram staggered through into the study. Mike, turning after re-locking the door, was just in time to see Psmith, with a display of energy of which one would not have believed him capable, grip the invader scientifically by an arm and a leg.

Mike jumped to help, but it was needless; the captive was already on the window-sill. As Mike arrived, Psmith dropped him on to the flower-bed below.
