“I am no coward!” he replied with fierce indignation. “If I were a coward I would accept the offer of your associates and pay willingly to be placed beyond the possibility of arrest. But I prefer to face the inevitable, and shall do so without flinching.” Then, turning to the others, he added: “I wish all three of you more success in your next attempt to squeeze money from an unfortunate criminal—that is all.”

He turned to leave, but Tonio, the hot-headed young bully, instantly sprang forward and drew from his belt a glittering knife, one of those long, narrow-bladed weapons which the Italian of the South usually carries out of sight on his person, although his paternal government forbids him so to do. Quick as thought Dudley divined the Italian wished to prevent him from leaving the house, and, seeing the knife held down threateningly before him, he raised his fist and with a rapid, well-directed drive from the shoulder struck the fellow beneath the jaw with such force that he was lifted up and fell backwards upon the table, overturning the cheap paraffin lamp standing there.

In an instant the place burst into flames. During the confusion that followed, while the woman rushed from the room screaming “Fire!” Dudley dashed out of the house, expecting, of course, to find his cab waiting for him.

But it was not there. While he had been arguing, the old hag had evidently paid the fare and dismissed the conveyance, a fact which was in itself sufficient evidence that they had not intended him to leave the house.

For a moment he hesitated. Then, recognising how narrowly he had escaped being struck down by an assassin, he turned and hurried away across the rough brickfield to which the unfinished road gave entrance.

Shouts of alarm, and loud cries of “Fire!” sounded behind him, but without turning to look he continued on his way, stumbling along in the darkness, utterly dumbfounded at his strange adventure and the remarkable revelation of the true character of the pretty young woman known in West End drawing-rooms as Muriel Mortimer.

For most of the remainder of the night Dudley Chisholm, unnerved by the strange affair and haunted by the constant dread that he was already under police surveillance, wandered through the deserted streets of Penge and Lower Sydenham. He feared to inquire the way from any of the constables he met, lest he should be recognised. As he was entirely unacquainted with the district, he knew his position was hopeless till there should be light enough to show him the Crystal Palace. Once arrived there, he could easily make his way back to London, for in days gone by he had often driven down in his tandem from Westminster, once or twice with Claudia at his side.

The night was dark, starless, and intensely cold. But he heeded not fatigue, for his mind was full of the gravest reflections. That the woman Mortimer, the mysterious ward of the Meldrums, had laid a very clever plot, into which he had fallen, was plainly apparent. But he had refused her demands, and she was now, of course, his most bitter enemy. That she would seek vengeance he had no doubt, for she had already shown herself to be a woman not to be thwarted.

And what was worse than all—she knew his secret.

Through the ill-lit suburban roads he wandered on and on, reflecting bitterly that with this woman as his enemy there only remained for him suicide, if he wished to avoid arrest and a criminal’s trial. He came at last to a railway line running on a low embankment, through market gardens, and it occurred to him to climb up there and wait in patience for the approach of a train. All this time Dudley Chisholm was not in the least distraught; and yet of all his wishes none was so powerful as the wish to end his life.
