At this juncture a low growl broke from the dog, and, guided by the sound, the youthful couple beheld, standing near the gate, the tall dark man in the black cloak. A fiendish smile sat upon his countenance.

"That is the man who frightened me!" cried Ebba.

"It is the person I supposed!" ejaculated Auriol. "I must speak to him. Leave me, Ebba. I will join you presently."

And as the girl, half sinking with apprehension, withdrew, he advanced quickly towards the intruder.

"I have sought you for some days," said the tall man, in a stern, commanding voice. "You have not kept your appointment with me."

"I could not," replied Auriol—"an accident has befallen me."

"I know it," rejoined the other. "I am aware you were assailed by ruffians in the ruined house over the way. But you are recovered now, and can go forth. You ought to have communicated with me."

"It was my intention to do so," said Auriol.

"Our meeting cannot be delayed much longer," pursued the stranger. "I will give you three more days. On the evening of the last day, at the hour of seven, I shall look for you at the foot of the statue in Hyde Park."

"I will be there," replied Auriol.
