100 Code (also known as The Hundred Code) is an internationally co-produced Swedish crime drama series, developed by Bobby Moresco, that first aired on German premium channel Sky Krimi on May 14, 2015. The series, which stars German-born British actor Dominic Monaghan and the late Swedish actor Michael Nyqvist, is based upon Ken Bruen's 2014 novel Merrick, and follows Tommy Conley (Monaghan), an NYPD detective who travels to Stockholm to advise and investigate a particularly gruesome series of murders.

Plot

Detective Tommy Conley travels to Stockholm to advise and investigate a particularly gruesome series of murders. Young, blonde, blue-eyed women are found murdered at regular intervals near water bodies and flower fields. Conley has to work with the Swedish investigator Mikael Eklund. The two hate each other, both fight with their own demons. After initial problems, the investigators investigate a series of murders, which, as initially thought, is not limited to New York and Stockholm, but has much larger dimensions.
