In "The Redbreast," Hole follows an assassin through Norway, though the job also takes him to South Africa. "Nemesis" deals with a bank robbery in Oslo. Hole stays in Oslo to track a serial killer in "The Devil's Star." "The Redeemer" has Hole tracking a hitman through Norway." In "The Snowman," Hole investigates a cold case regarding a Norwegian serial killer.
After "The Snowman," Hole moves to Hong Kong for a self-imposed exile. He returns to Oslo to investigate a series of murders in "The Leopard." He returns to Hong Kong after that, then goes back to Norway in "Phantom" to investigate a murder for which his girlfriend's son is the main suspect. In "Police," he investigates a serial killer targeting the Oslo police.
