“The Spy” is the fifth novel in the series about detective Jon Lynn. Lars Kepler (the pseudonym of the Andoril couple) offers readers another example of an impeccable thriller. The police receive a link to a short video clip: someone was secretly filming a woman through a window. The next morning she was found dead. Soon another clip arrives - with a new victim. And then another one, just minutes before the massacre. The police are unable to get on the trail of the killer, who acts with extreme cruelty: all the victims have their faces cut with a knife, as if the criminal wanted to erase them. Commissioner Margot Silverman took on the task of stopping a series of terrible, seemingly illogical murders; this is her first independent investigation. The investigation would have reached a dead end if John Lynn, whom everyone considered dead, had not intervened. In a strange way, psychiatrist Eric Maria Bark is involved in the case: he gets a very unexpected role in this dark story.
