A new thrilling detective novel by the winner of the Grand Prix of the French Academy and the Goncourt prize for high school students—the author of the sensational bestsellers “The Truth About the Harry Quebert Affair” and “The Baltimore Book”—Joël Dicker. A popular young writer arrives at the luxurious “Palace Verbier” hotel, tucked away in the Swiss Alps, to rest, gather his thoughts, survive a breakup with his beloved, and cope with the death of his dear friend and publisher. Breathtaking views, sun-drenched landscapes, mountain-fresh cold air, terraces, a jacuzzi pool, fires in the rooms, and the soft half-light of the bar—an ideal place to forget all worries and hardships. But by chance the hero learns that years ago a mysterious murder took place in the neighboring room, number 622. Out of curiosity, he starts asking questions and finds himself pulled into an incredible and dangerous whirlpool of conspiracies and intrigues, where Swiss bankers, heirs of Russian noble families, all-powerful intelligence services, and desperate adventurers become intertwined.
