She emptied the purse into her own hand, and solemnly counted out the twenty pieces of gold. She was about to replace them all into the purse, when Marguerite pressed one of them back into her wrinkled hand.

“Nineteen will be enough, citizeness,” she said; “keep one for yourself, not only for me, but for all the poor women who come here with their heart full of hope, and go hence with it full of despair.”

The woman turned calm, lack-lustre eyes on her, and silently pocketed the gold piece with a grudgingly muttered word of thanks.

Chauvelin during this brief interlude, had walked thoughtlessly on ahead. Marguerite, peering down the length of the narrow corridor, spied his sable-clad figure some hundred metres further on as it crossed the dim circle of light thrown by one of the lamps.

She was about to follow, when it seemed to her as if some one was moving in the darkness close beside her. The wardress was even now in the act of closing the door of her cubicle, and there were a couple of soldiers who were disappearing from view round one end of the passage, whilst Chauvelin’s retreating form was lost in the gloom at the other.

There was no light close to where she herself was standing, and the blackness around her was as impenetrable as a veil; the sound of a human creature moving and breathing close to her in this intense darkness acted weirdly on her overwrought nerves.

“Qui va la?” she called.

There was a more distinct movement among the shadows this time, as of a swift tread on the flagstones of the corridor. All else was silent round, and now she could plainly hear those footsteps running rapidly down the passage away from her. She strained her eyes to see more clearly, and anon in one of the dim circles of light on ahead she spied a man’s figure—slender and darkly clad—walking quickly yet furtively like one pursued. As he crossed the light the man turned to look back. It was her brother Armand.

Her first instinct was to call to him; the second checked that call upon her lips.

Percy had said that Armand was in no danger; then why should he be sneaking along the dark corridors of this awful house of Justice if he was free and safe?
