Stockholm's detective extraordinaire, Joona Linna, is back in this sequel to the best-selling first novel The Hypnotist . Joona is invited to join Sweden's elite-of-elite crime-solving team called "The Commission" as its sixth member. This small group of investigators are "...responsible for combating serious crime at both the national and international level...." Joona declines the prestigious offer since they mandate a regimented procedure for investigating crimes. Variations to the theme are not welcomed.
Joona is the modern-day combination of a Swedish Sherlock Holmes  and action star Chuck Norris . He basically has free reign over what cases he gets involved in and what means he uses to solve them. The nice part is that he is not pretentious or self-centered. He is just uncannily always right.
The Nightmare  has Joona investigating several murders whose connection is apparent, at first, only to him. A renowned pacifist and her lover are on the run from a robotic-like professional killer. The assassin is searching for a photo that would compromise a major arms deal if released to the public. The person who has ordered the killings has an unusual way of conducting business. Contracts are never signed. What he requires, in order to complete all business transactions with his future partners, is their willingness to share their worst nightmare.
Alexander Ahndoril and his wife Alexandra Coelho Ahndoril write under the pseudonym Lars Kepler . These Swedish authors had a breakaway best-seller last year with The Hypnotist . The film version's release date is set for September in Sweden. The movie is about "a detective who pairs himself with a famous psychologist on a case involving a traumatized young witness to a crime."
