The fourth man
(Book)

"In the course of a routine police raid, Detective Inspector Frank Frølich of the Oslo Police saves Elizabeth Faremo from getting inadvertently caught in the crossfire. Some weeks later, Frølich coincidentally runs into her again—but their ensuing affair is no accident. By the time he learns that she is no stranger—but rather the sister of a wanted member of a larceny gang—it is already too late. In the middle of one night, Frølich receives a call that a young guard has been killed in the course of a robbery. Scrambling to respond, he realizes that Elizabeth is no longer in his bed. In a turn of events cryptic, erotic, and complex, he finds himself a prime murder suspect and under the watch of his doubting colleagues. Led through the dark underworld of Oslo, Frølich must find out if he is being used . . . before his life unravels beyond repair."--,Amazon.com.
