“Memphis Cafe!” muttered Helen, glancing at him rapidly; “what an odd name.”

“Ah! my dear Miss Cumberly!” cried Gianapolis, with triumph—“I knew that you had never heard of the true haunts of Bohemia! The Memphis Cafe—it is actually a club—was founded by Olaf van Noord two years ago, and at present has a membership including some of the most famous artistic folk of London; not only painters, but authors, composers, actors, actresses. I may add that the peerage, male and female, is represented.”

“It is actually a gaming-house, I suppose?” said Helen, shrewdly.

“A gaming-house? Not at all! If what you wish to see is play for high stakes, it is not to the Memphis Cafe you must go. I can show you Society losing its money in thousands, if the spectacle would amuse you. I only await your orders”...

“You certainly interest me,” said Helen; and indeed this half-glimpse into phases of London life hidden from the world—even from the greater part of the ever-peering journalistic world—was not lacking in fascination.

The planning of a scheme in its entirety constitutes a mental effort which not infrequently blinds us to the shortcomings of certain essential details. Denise's plan, a good one in many respects, had the fault of being over-elaborate. Now, when it was too late to advise her friend of any amendment, Helen perceived that there was no occasion for her to suffer the society of Gianapolis.

To bid him good evening, and then to follow him, herself, was a plan much superior to that of keeping him company whilst Denise followed both!

Moreover, he would then be much more likely to go home, or to some address which it would be useful to know. What a VERY womanish scheme theirs had been, after all; Helen told herself that the most stupid man imaginable could have placed his finger upon its weak spot immediately.

But her mind was made up. If it were possible, she would warn Denise of the change of plan; if it were not, then she must rely upon her friend to see through the ruse which she was about to practise upon the Greek.

“Good night, Mr. Gianapolis!” she said abruptly, and held out her hand to the smiling man. His smile faded. “I should love to join you, but really you must know that it's impossible. I will arrange to make up a party, with pleasure, if you will let me know where I can 'phone you?”
