The novel, winner of the “Masters of Horror” award, immerses the reader in the atmosphere of Baltic noir and introduces the darkest corners of the soul of an elusive killer who appeared in Tallinn. The police are unsuccessfully trying to catch the Absorbent, who terrorized the entire Estonian capital, while the writer Otto Vernell had the courage to take on a joint book with the maniac and try to understand him. But what will the price of the future bestseller be? And most importantly, who is he now: a co-author, an accomplice or the next victim? “Co-authorship” is a story about the darkness inside a person and the inability to resist it, about denial, self-defense and helplessness. And that looking into the depths of one’s own soul can sometimes be scarier than writing a thriller in collaboration with a serial killer. Prize from the Film Studio “10/09” in the category “Best Debut.” Film rights sold.
