"You will dine with us, Miss Kendall?" he asked. "Then we will plan the next step in our campaign."

"I shall be glad to do so," she replied.

Fifteen minutes later I had dropped the letter in the drop of a branch of the general post-office to ensure its more prompt delivery, and it was on its way through the mails to accomplish the purpose Kennedy may have contemplated.

"Just now it is more important for us to become acquainted with this Little Montmartre," he remarked. "I suppose, Miss Kendall, we may depend on you to join us?"

"Indeed you may," she replied energetically. "There is nothing that we would welcome more than evidence that would lead to the closing of that place."

Kennedy seemed to be impressed by the frankness and energy of the young woman.

"Perhaps if we three should go there, hire a private dining-room, and look about without making any move against the place that would excite suspicion, we might at least find out what it is that we are fighting. Of course we must dine somewhere, and up there at the same time we can plan our campaign."

"I think that would be ripping," she laughed, as the humour of the situation dawned on her. "Why, we shall be laying our plans right in the heart of the enemy's country and they will never realize it. Perhaps, too, we may get a glimpse of some of those people mentioned in the anonymous letter."

To Clare Kendall it was simply another phase of the game which she had been playing against the forces of evil in the city.

The Little Montmartre was, as I already knew, one of the smaller hotels in a side street just off Broadway, eight or ten stories in height, of modern construction, and for all the world exactly like a score of other of the smaller hostelries of the famous city of hotels.
