While this novel may not rank among the best thrillers I've encountered, it's certainly not the worst either. There were moments during the story's unfolding that I genuinely enjoyed, particularly the character of Professor Hans Rekke. His internal battle with mental health adds a layer of depth to his personality, making him a fascinating figure within the narrative.

However, I found both Rekke and Micaela Vargas, the two central characters, to be somewhat exaggerated in their portrayals. Rekke, a supposed musical genius, possesses a remarkable logical mind, yet some of his deductions stretch the limits of plausibility. This reliance on implausible conclusions detracts from the overall believability of the story, leaving it feeling somewhat unrealistic at times
