Elderly heiress Celeste Van Duren intended Marchfield Square to be a haven from the outside world. A place for those who need somewhere safe from their pasts, or who could otherwise not afford to stay in the city they call home. That was the plan. One of her tenants being murdered in his own kitchen, and the police trying to pin it on his long-suffering wife, was not. So Celeste does what anyone with a lot of money, a strong sense of justice and a bad hip would do: she recruits two of her tenants to track down the real killer. Her cleaner, Audrey, knows everyone and is liked by all, while failed crime writer, Lewis, is known by no one. He hates his job, hates his life, and he's not that fond of Audrey either, but Celeste is persuasive. Despite their differences the two soon discover a surprising range of suspects and motives connected to the victim's dodgy art deals - but have they missed something closer to home?
