Half a thousand men gave chase; but the assailant had escaped to the common shelter of the coasting town. He had taken to the water.

It was now quite dark; clouds had gathered; the wind had risen suddenly; thunder was heard. A fierce gust tore the dust of Angel Alley, and hurled it after the fleeing criminal; as if even the earth that he trod rejected him. In this blinding and suffocating whirlwind the pursuers stumbled over each other, and ran at haphazard. The police swept every skulking-place, dividing their forces between the Alley and the docks. But their man, who was shrewd enough, had evaded them; it was clear that he had marked out an intelligent map of escape, and had been able to follow it.

The baffled police, thinking at least to pacify the angry people behind them, kept up that appearance of energy, with that absence of expectation, for which their race is distinguished.

An officer who was stealthily studying the docks far to the westward, and alone, suddenly stopped. A cry for help reached him; and it was a woman’s cry. The voice kept up an interrupted iteration:—

“Police! Help!—Murder! Sergeant!—Help! Help!” as if choked off, or strangled in the intervals.

The sergeant, following the sound as well as he could, leaped down the long, empty wharf from whose direction the cry seemed to come, and peered over the slimy edge. The storm was passing noisily up the sky, and the darkness was of the deepest.

Out of its hollow a girl’s voice uprose:—

“Sergeant! Sergeant! He’s drowning me! But I’ve got him!” and bubbled away into silence.

At that moment there was lightning; and the outlines of two figures struggling in the water could be distinctly seen. These two persons were Lena and Ben Trawl. They seemed to have each other in a mutual death-grip. The girl’s hands were at the man’s throat. He dashed her under and under the water. But her clutch did not relax by a finger. He held her down. But Lena held on.
