The Maid meets Only Murders in the Building in this twist-packed cosy mystery set in the smallest residential square in London.

Marchfield Square was meant 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 Celeste Van Duren's 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 some help to track down the real murderer. Her cleaner, Audrey, knows everyone in the square 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. In theory his knowledge of police procedure and her way with people should help them find the killer - if they don't kill each other first...

Despite their differences the two soon discover the victim's dodgy art deals may hold the key to the mystery – but have they missed something closer to home? After all, how well do you really know your neighbours?
