The new thriller from #1 international bestselling author Guillaume Musso.

PARIS, CHRISTMAS 2021. After a heart attack, Mathias Taillefer wakes up in the hospital with a stranger at his bedside. The mysterious girl reveals herself to be Louise Collange, a volunteer who has come to play the cello for patients.

When she finds out that Mathias is a cop, she asks him to look into a very special case. Her mother, a former ballerina at the Paris Opera Ballet, died last year after falling from her balcony, and Louise has a hunch she was pushed. Though hesitant at first, Mathias agrees to help her, sending them both headfirst into a deadly chain of events. And at the centre of it all, a woman named Angélique, whose angelic intentions may not be all they seem.

Feverous, surprising and uplifting, Musso's newest novel is a labyrinth of emotions where nothing is certain from one page to the next.
