"'Arf a mo, sir. If I didn't wing 'im, I'll bet I've 'eaded 'im orf to the right"; and he sent a brace of bullets pinging into the darkness.

"Lor lumme!" he chuckled the next moment, "there ain't no fool like an Allemong. What did he want to fire back for?" And he wiped a great gout of the chalky mud that had splashed up into his face as a Mauser bullet struck the ground between them. "'E's in that 'ole to the right—that's where we'll find 'im, sure as my name's 'Arry 'Awke. Come on, sir, don't make a sound!"

With the switching off of the searchlights the enemy barrage had ceased, and the deafening crash of the German shells was succeeded by a weird silence.

The distant boom of the British firing seemed very far off and almost insignificant in that sudden transition, and recharging his empty revolver as he went forward, Dennis wormed himself cautiously to the edge of the crump-hole, where he hoped to find his enemy.

It was still pouring in torrents as his chin came on a level with the ragged rim, but the fierce hope died out of his heart.

The shell-hole was an old one, the rain had filled it almost to the brim, and he ground his teeth, knowing that the spy had outwitted them after all. He knew now that, in spite of Hawke's shots, the villain with the charmed life must have chanced his arm and kept straight on between the two shell-holes, and would even then be nearing the German position, gloating over his success.

"I have missed the chance of my lifetime," he thought bitterly, when a star shell burst directly above him, lighting up the rain pool like a sheet of silver.

He had already picked himself up, and was clearing his throat to give his unseen companion a hail, when a warning whistle came from the opposite edge of the hole, and he saw Hawke's head and shoulders and a pointing arm.

Among the splashing raindrops in the centre of the pool a white face parted the water.

It was Von Dussel come up to breathe, and as the face sank out of sight again, Dennis dived in after it, regardless of all consequences.
