"Why not leave the door open?" suggested Dudley.

"An' let the bounder go scot-free?" added Laxdale, a gleam of grim determination in his eyes. "No jolly fear. We'll lay him out properly. Here you are, take this."

He handed Wilmshurst a towel roller made of teak, forming a heavy and effective weapon.

"This is where I think the brute's hiding," continued Laxdale, indicating a long drawer under the lowermost bunk. "I was stowing some of my gear away when I spotted him. After five minutes' strafing he disappeared, but goodness knows how he managed to get through that little slit. Now stand by."

Entering into the spirit of the chase Dudley knelt down and waited with poised stick while Laxdale charily opened the drawer. Like most drawers on board ship and frequently elsewhere it jammed. By frantic up and down movements the subaltern freed it. Then he waited, both officers listening intently. Not a sound came from within.

"Don't suppose the brute's there after all. He must have effected a strategic movement.... Look out, by Jove!"

Acting upon his impression Laxdale had tugged the drawer half open. Instantly there was a vision of a dark object darting with lightning-like rapidity.

Down came Wilmshurst's towel roller a fraction of a second too late for Mister Rat. At the same time Laxdale moved his hands along the ledge of the drawer and received the full force of the blow across the knuckles.

"Sorry!" exclaimed Wilmshurst.

Laxdale, nursing the injured hand, made no audible comment. Deliberately he relieved Dudley of the towel-roller, throwing his companion the knotted towel in exchange.
