I devoured it last month, and while the central murder mystery is fine—a wealthy socialite poisoned at a gala, the usual suspects in a locked ballroom—what stuck with me was the protagonist. She's a jaded art authenticator, not a detective, and her way of spotting forgeries through brushstroke patterns gets weirdly applied to people's lies. The plot mechanics are standard, but her perspective, that clinical detachment bleeding into paranoia, made it feel fresh. The ending's reveal felt a bit rushed, though. I guessed the culprit around the 70% mark, but the 'why' was more nuanced than I expected.
Worth it? If you're after a pure, twisty adrenaline ride, maybe not. But if you like your thrillers character-driven with a slightly off-kilter, intellectual process, you'll probably enjoy the ride. I'd put it in the same category as 'The Silent Patient' for that unreliable, psychologically fraying narrator vibe, just with more art world glitz.
