Mord, lilla vän (1955)

A member of "Sjöbjörnarna" (a group of executives), asks the newspaper editor Dick Mattson to find Brita Ljungdahl, the former wife of another of the members. The first clue he tries is to ask a certain Maria Vaern, who knows Brita. However, he discovers that she is dead by suicide and when he soon finds Brita, he starts wondering if Maria really did commit suicide or if she was murdered. When a private detective, who was contacted by Maria, contacts him but is later murdered, he starts looking deeper into the affairs of "Sjöbjörnarna". He discovers that the accident last summer, in which one memeber of the group was killed, was not an accident and his search even takes him to Paris and back. Meanwhile, he and Brita, who once were lovers, start discovering each other again.
