Meet the most unforgettable heroine since Eleanor Oliphant: Zofia, the Polish mother who pretends to be a cleaning lady in order to discover what really happened to her missing son.

'If you're looking for irresistible prose, it's here in this book. The protagonists' voices criss-cross in a near impossible harmony of heart, guts, shrewdness and nerve. If it's a story you're after, that's here too' Helen Oyeyemi

Zofia's troubled son, Janek, is missing. She leaves her native Warsaw and arrives in London to investigate whether a famous writer, Steve, had something to do with the disappearance.

To fund the operation, headstrong Zofia has borrowed a lot of money and been forced to take cleaning jobs - a professional trajectory she finds very much beneath her. Zofia's heavy-handed, DIY investigation soon yields some results: Steve does have skeletons in his closet. Two are of particular interest: he stole Janek's novel and published it as his own; and he's now dating Janek's ex-boyfriend...

Steve and Zofia soon join forces to unravel this mystery. There's an unsolved murder, a stolen book, and a missing boyfriend - all that before Zofia and Steve even begin to face the fact that they both played a part in creating this almighty mess.

Just as hilarious as it is thought-provoking, this unputdownable and genuinely one-of-a-kind page-turner is perfect for fans of Jonas Jonasson, Fredrik Backman and Eleanor Oliphant is Completely Fine.
