A partially dressed Detective Sergeant Dagmar Johnson wakes up lying next to an unknown man in an unknown house. In an attempt to discover how she ended up there, events that follow, lead her to an encounter with an organised crime gang heavily into prostitution, money laundering, loan sharking and the supply of heroin. Dagmar Johnson is serving penance in a specialised detective unit because she has had a history with alcohol.

Dagmar Johnson's childhood in Düsseldorf defines her character and her sexuality. Just how does a bisexual half American and half German female with some unusual and unapproved IT skills end up in the police service in London?

Together with her on-line buddy, Lucius and his nefarious bug, XTC, Dagmar Johnson goes about breaking down an organised gang and exorcising her own demons. Is she successful?
