How long I could have remained an angel at that price I'm not sure. But a letter came to me from Maida next day to say that she had decided not to become a life member of the Grey Sisterhood.

EPISODE VI

THE CLUE IN THE AIR

If I had been fighting my own battle, not Maida's, against Doctor Rameses, I might have sometimes admired his cleverness. There seemed to be no way of catching him.

The police theory was that some person, not Rameses, took advantage of the "philanthropist's" conspicuous appearance to commit crimes in a disguise resembling his peculiarities. This, they thought, might be done not only as a means of escaping detection, but with the object of blackmail. My theory was different. I believed that Rameses had a confederate enough like him in looks to deceive an audience assembled for one of his lectures, or patients undergoing his treatment.

I did not hesitate to assert this opinion, hoping to provoke the man to open attack.

After the affair of the opium den, he lay low. Nothing happened in which, by any stretching of probabilities, he could have had a hand. Perhaps, thought I, he had learned that I was a hard nut to crack! Two-thirds of the time for which Maida had promised herself to the Grey Sisterhood passed. Her doubts of me had been swept away, and I hoped to find at the end of the year that I hadn't waited in vain. Now and then I saw, or believed that I saw, light on the mystery of Maida's antecedents. Altogether I was happier than I had been and I was serving my country's interests while I served my own.

I had been ordered to buy desirable new types of aeroplanes, and luckily got hold of some good ones. The "story" of my mission suddenly appeared in the newspapers, and interest in my old exploits as a flying man were revived embarrassingly. I was "paragraphed" for a few days when war tidings happened to be dull; and to my surprise received an invitation to demonstrate my "stunt" of looping a double loop at a new aviation park, opened on Long Island. The exhibition resulted in another compliment. I was asked to instruct a class of young aviators, and was officially advised by the British Ambassador to accept. I did accept: and was given a "plane" and a hangar of my own; but I kept on my suite in the hotel near Sisterhood House, starting at an early hour most mornings to motor to the aviation ground.

After a few weeks of this, a big aviation meeting took place, and when my part in it was over I found myself holding quite a reception in my hangar. Friends and strangers had kind things to say: and while I explained new features of my 'plane to some pretty women, I saw a prettier woman gazing wistfully at me between hats.
