Exhausted after a gruelling world tour, international cellist Sara Selkirk is looking foward to a few months' recuperation at her picturesque cottage near Bath. But her growing attraction to the music-loving DCI Andrew Poole causes her to make the mistake of joining an amateur operatics society. The Circus Opera Group is a motley crew: There's faded diva Helene and her autistic daughter Adele; vain, talentless composer Cosmo and his long-suffering girlfriend, Poppy. Not to mention Andrew's wife, who's beginning to grow suspicious. With this uneasy mix and clash of fragile egos, both Sara and Andrew predict trouble ahead. What they don't expect to encounter is sudden, violent death.
