The set will not fail to think of the great Shutter Island, with a hero who believes switch a little more each day into madness, and although the final twist is a little convoluted, with several successive twists, the drive remains rather shocked such a success, before this unexpected outcome. Only writing is still a little weak, with a style that is not encumbered frills and goes straight to the point to preserve intact the suspense, but Fitzek is far from the only crime writer to have to wipe this reproach. In short, a strong first novel, effective psychological thriller dreaded "page turner" since it consumes in one night, dark and ominous, which takes its reader in suspense until the last page ... and more. Thrills guaranteed!
