In something less than two minutes she had left it again by a back entrance, stepped into another taxicab which was just setting down a passenger, and was well on her way back towards Pall Mall.

Her ruse appeared to have been perfectly successful.

At any rate, she saw nothing more of the occupants of the two taxicabs.
She stopped in front of one of the big clubs and, scribbling a line on her card, gave it to the door keeper.
"Will you find out if this gentleman is in ?" she said.

"If he is, will you kindly ask him to step out and speak to me ?" She returned to the cab and waited.

In less than five minutes a tall, broad-shouldered young man, clean-shaven, and moving like an athlete, came briskly down the steps.
