"Perfectly," I said.

"And not a word must pass your lips—not to a soul," he urged. "For each success we gain in the various missions entrusted to us you will receive from the Secret Service fund a handsome honorarium as acknowledgment of your faithful services."

Then he walked away, gaily singing the gay chanson of Magda at the Ambassadeurs:

"Sous le ciel pur ou le ciel gris
Dès que les joyeux gazouillis
Des oiselets se font entendre,
Une voix amoureuse et tendre
Par la fenêtre au blanc rideau
Lance les couplets d'un rondeau;
C'est la voix d'une midinette
Qui fait, en chantant, sa toilette.
Ah! le joli réveil-matin,
Quand il faut partir au turbin!
Bientôt, de la chambre voisine,
Répond une voix masculine.
Paris! Paris! Gai paradis!
Voilà les chansons de Paris!"

Much gratified at securing such a post, I drove the Honourable Robert back to London and waited for him in the courtyard of the Hotel Cecil while he was inside for a quarter of an hour. Then, getting up beside me he directed me to drive to Hammersmith Bridge, where, at a big block of red-brick flats overlooking the river, called Lonsdale Mansions, we pulled up, and he took me up to his small cosily furnished flat, where William, the clean-shaven and highly-respectable valet, awaited him.

The "ninety" was garaged, I found, almost opposite, and when I returned to the flat the Honourable Robert was at the telephone in the dining-room talking to the man we had left near Welwyn.

The elderly woman who acted as cook showed me my room, gave me my dinner, and I sat smoking with William for an hour or so afterwards.

The valet was a very inquisitive person, and I could not fail to notice how cleverly he tried to pump me concerning my post. He, however, failed to obtain much from me.

"The guv'nor is one of the best fellows alive—a thorough sportsman," he informed me. "Respect his confidence, and don't breathe a word to any one as to his doings, and you'll find your place worth hundreds a year."

"But why these strict injunctions regarding silence?" I inquired, in the hope of learning something.
