Becoming a courtesan is a strange desire. However, for a beauty who was forced into marriage almost as a child, became a victim of drunken violence on her wedding night and abandoned the next morning, such a fate does not seem such a bad solution. A woman calling herself Diana Lindsay appears in the capital - and brings the entire London demimonde to her feet. Future owners and patrons literally lie at her feet. But suddenly Diana, with horror, recognizes in one of them the man who once ruined her life - her lawful husband Gervase Brandelin, Viscount St. Aubyn! Gervase, one of the best British masters of the "secret" spy war against Napoleon, falls in love with a beautiful courtesan with at first glance. But why does she so stubbornly reject his advances, what is she afraid of?..
