Lust

Written by famed poet Christopher Logue (who probably needed money) and first published under the Ophelia imprint, Lust is a kind of "how to succeed in business without really trying." The tale follows its hero from a dreary office setting where a superior's wife discovers the pair share mutual interests, into the clutches of one Mr. Bulles, who sends him (and the girl Anna) on missions of espionage and intrigue.
Later he encounters royalty, multiple partners, before finishing, as all great espionage novels must, in revolution.
