Showing Revenge of the Spellmans by Lisa Lutz

Having been ordered into therapy after getting a little too close to her previous subject, former private investigator Izzy Spellman is wisely taking a break from Spellman Inc, having embarked on a less controversial career as a barmaid. But when her boss, Milo, simultaneously cuts her bartending hours and introduces her to a 'friend' looking for a private eye, Izzy reluctantly finds herself with a new client. A suspicious husband who wants his wife tailed, it would appear to be a routine case involving nothing more than that most boring of PI rituals: surveillance. But Izzy soon discovers that she's not the only person keeping a close eye on Mrs Ernie Black and with each passing hour the Case of the Wayward Wife throws up more questions than answers.
