Welcome to No.12 rue des Amants. A beautiful old apartment block, far from the glittering lights of the Eiffel Tower and the bustling banks of the Seine. Where nothing goes unseen.And everyone has a story to unlock. The watchful concierge. The scorned lover. The prying journalist. The naïve student. The unwanted guest. Something terrible happened here last night. A mystery lies behind the door of apartment three. Only you – and the killer – hold the key . . .
