There was a brief hesitation. Then, "Billy."

Rutledge doubted that it was, but the name would do.

Hamish warned, "Have a care. There's no one about."

Even as he spoke the words, Big Ben behind them struck one.

Trying to reason with his assailant, Rutledge said, "You don't want to do this, Billy. I'll help you find work, if that's the problem. I give you my word." There was a distant splash. "My watch is next," he commented, taking advantage of the sound. "I won't turn you over to the police if you give me the knife now."

He could feel the boy's uncertainty in the pressure brought to bear on the blade against his back. He could feel too the twisting of the boy's body to look up and then down the bridge for witnesses. And then the pressure increased.

The time had come.

Before his attacker could shift his weight and drive the knife home, Rutledge wheeled and caught Billy's free arm in an iron grip, twisting it behind him in a single move. His other hand reached for the knife. Startled, the boy cried out, and Rutledge misjudged the swift reflexes of the young.

The knife flashed as it swung wildly in the direction of Rutledge's face. Before he could force it away and down, it sliced through his coat and into his right arm as Billy fought with the strength of fear.

Rutledge swore and ruthlessly pinned his assailant against the parapet, knocking the wind out of him for an instant as his fingers bit into the wrist of the hand with the knife. It flexed, and all at once the knife spun in the air, catching the lamplight before it clattered on the pavement. Rutledge managed to kick it out of reach, then concentrated on subduing the boy, gradually forcing his body backward until the fight went out of him.

He was just reaching for the cap that half covered Billy's face when he heard a constable's whistle and the heavy thud of his regulation boots as he came pounding over the crest of the bridge.
