Marion Op den Camp Book order (chronological)

A murder causes tensions in the McCarthy's household to build; Jack, Madeleine's father must decide where his loyalties lie. Madeleine learns about the ambiguity of human morality - a lesson she will only begin to understand when she carries her quest for the truth, and the killer, into adulthood.

Growing up as a foster child among a family of thieves, orphan Sue Trinder hopes to pay back that kindness by playing a key role in a swindle scheme devised by their leader, Gentleman, who is planning to con a fortune out of the naive Maud Lily, but Sue's growing pity for their helpless victim could destroy the plot.
