Jørn Lier Horst, who this year won the Glassnøkkelen, one of Scandinavia's most prestigious crime-writing awards, said that the success of his fictional creation, Police Inspector William Wisting, was making it impossible for him to pursue his real-life investigations.
"It's the time pressure that has made me stop. With a full-time job in the police and four books in as many years, I simply do not have the time," he told VG newspaper. "There has been little time for family. As well as my two full-time commitments, I have a wife and two children I would like to spend time with."
Horst spent nine years in the police before finding success in 2004 with Key Witness, the first of his eight Wisting novels.
