"I do so wish you would, Sir Humphrey," Ena said. "I want to get back to Scotland, as I have to go to Ardlui next week."

The great doctor took the telephone at his elbow, and was soon talking to Doctor Hepburn, with whom he arranged for the lady to call in an hour.

Then Sir Humphrey scribbled the address in Harley Street on a slip of paper, and with a few polite words of reassurance, rang his bell, and the man-servant conducted her out.

"An exceptionally pretty woman," grunted old Sir Humphrey to himself when she had gone. "Highly intelligent, and a first-class life."

And he sat down to record his own private views as to the physical condition of the person proposed for insurance.

Ena idled before the shop windows in Oxford Street for three-quarters of an hour, and then took a taxi to Harley Street, where she found Doctor Stanley Hepburn, a short, stout, brown-bearded man of rather abrupt manner.

In his smart, up-to-date consulting-room he put the same questions to her, wearying as they were, and parrot-like she answered them.

"Truly, I'm having a busy morning, doctor," she remarked, with a sigh, laughing at the same time.

"Apparently," he said, smiling. "I must apologise for bothering you with all these questions. Sir Humphrey has, no doubt, gone through them all."

"He has."
