Crouch End Confidential, the agency started by housewife and mother, Cathy O'Farrell, with ex-cleaner, Pimple, is failing badly. Hardly surprising when Cathy's too soft-hearted to charge their only clients, little old ladies seeking lost pets and a school kid searching for his stolen bike.
A new case involving a teenager in possession of an unexplained Glock pistol promises to change all that. Quickly Cathy's deep in waters over her head, forced with hilarious results to pose as a mathematics tutor, a subject of which she's truly clueless. There's also the tricky situation of best friend and new mother Rosa hiring her to investigate her fiancé, Alec, plus the mysterious sabotage of Cathy's friends' cycle shop and a gang of yobbos dealing drugs at her children's primary school.
Worst of all, an ill-fated trip to rural Norfolk has Cathy's husband, Declan, intent on buying a post office and transplanting the family to safer climes, threatening to tear Cathy permanently from her beloved North London home.
Pretty soon Cathy's risking her friendships, her marriage and even her life untangling all these messes. But that's what you get for meddling in murder...
