The assignment that took John Gail to Paris was blackmail with a political motive. It introduced him to a two-way mirror, a beautiful receptionist, a seductive schoolgirl, a ruthless gang of political opportunists. It involved him in deadly danger, pursuit, torture - and the invitation to imprison himself. The price he paid was high - but the stakes weren't low either. The peace of the world. John Gail was of the flesh, fleshly. So were Lilly and Louise. The flesh of pleasure and the flesh of pain. Note: the author of this book, Stephen D. Francis, is probably better known as (the notorious) "Hank Janson" but here writes under his own real name.
