Having just finished the book, the whole suspect list is practically a who's who of everyone staying at the Verbier resort. The initial obvious one is the hotel owner's ambitious son, Jean-Baptiste, who stands to gain from the whole mess. But the real weight of suspicion shifts as you read, especially towards the financial backers from that mysterious investment group – one of them, Lev, gives off seriously shady vibes. Even the seemingly helpful concierge has moments where her knowledge seems a bit too convenient.
What tripped me up wasn't just the characters, but the structural trickery. The translator character and the whole meta-layer about the author himself, Joël, end up being potential suspects in a different kind of puzzle. By the end, I was less sure about 'who' and more focused on 'why,' because the motive gets so twisted with all that banking intrigue and personal revenge. It's classic Dicker, making you doubt your own deductions.
