I Will Find The Key (häftad, eng)

Private investigator Julia Stark receives an unannounced visit at the office. The man at the door is one of the owners of a successful family business. The day before, he was present at a board meeting and dinner at his estate in the northwestern part of Sweden. The following morning, he finds a photograph in his phone of a bloody
man, tied up with a bag over his head.

Due to alcohol-related amnesia, the man has no idea where the picture comes from and wants to hire Stark Detective Agency to clear his name before the police get involved. Julia asks her ex-husband Sidney Mendelson to take time off from the City Police and assist her in the investigation. There is still a glimmer of hope left in Julia that this might be her chance to win him back.

Welcomed as guests at the opulent estate, Julia and Sidney begin to search for the truth while dining and socializing with each of the family members that could theoretically be involved in the murder.
