With trademark style and charming whimsy, Antoine Laurain's new novel of intrigue, murder and neighbourly curiosity is sure to delight fans old and new.

Nathalia Guitry was a successful photographer. Until the day she caught a murder on camera.

At therapy, Doctor Faber suggests a way out of her creative block: she must write stories about the people she sees in the building opposite, floor by floor.

Starting with the actor turned YouTube life coach on the ground floor and going all the way to the fifth via a cartoonist and an ex-trader, Nathalia creates vivid accounts of her Parisian neighbours' lives. But are her tales real or imaginary? As their sessions play out, the doctor becomes increasingly uncertain.

And when she gets to the final floor, it's up to Faber to do the talking . . .

Suspense, intrigue and sly wit abound in the latest novel from bestselling author Antoine Laurain.
