“Well—there is no harm in giving you the caution, old tiger-cat,” remarked the Doctor, carelessly. “So tramp off—and be punctual to our appointment.”

“I shall not fail,” said the horrible woman, who thereupon took her departure.

How she passed the remainder of that day, we know not. Suffice it to say that the leisure-time which she had for reflection did not induce her to change her mind nor swerve from her purpose: on the contrary, as she entered Sloane Square a few minutes before midnight, it was with a determination to take her share in the awful tragedy which she contemplated—namely, the murder of her own daughter and the Count of Carignano. Bad and depraved as she was, never in her life until this occasion had she thought so calmly and coolly of shedding blood: for if on the previous day she had harboured the design of assassinating Jack Rily, in order to regain possession of the Bank-notes, it was not without a cold shudder, even though there was something like aggravation to inspire the idea. But now she had brought herself—or circumstances had tutored her—to survey with a diabolical tranquillity the hideous, appalling crime which she had in view; and as she walked along, she clutched with savage triumph a clasp-knife that she had purchased during the evening.

Precisely as the clock struck twelve Jack Rily joined her.

“Well, you have not altered your mind?” he said.

“It is rather for me to ask you that question,” was her response.

“Oh, I am resolute enough!” he observed; and through the semi-obscurity of the night she could see his large white teeth flashing hideously between the opening in his lip. “I have taken a good survey of the premises,” he continued, “and know exactly how to proceed. Have you got any weapon, old tiger-cat?”

“This,” she replied, placing the clasp-knife in his hand.

He opened the blade—felt it—closed it again—and, returning the knife to his companion, said, “That will do. But there is one thing that troubles me a little,” he added, after a few moments’ hesitation; “and I’ll be hanged if I can get it off my mind. Yet—perdition seize it!—I am no coward either.”

“What have you to fear, then?” demanded the old woman, hastily.
