An apartment building. A woman clearing up the mess her three-year-old son has made on the stairway. A child staring into an open doorway. The naked leg of a woman sticking out of that doorway. Blood. A woman's scream.

Reidun Rosendal's murder presents Oslo detectives Gunnarstranda and Frolich with their most intriguing case yet. And the mystery deepens when the chief suspect, Reidun's lover, is also found murdered.

As the investigation proceeds the focus shifts to Reidun's place of work, Software Partners, where the business and the private lives of the characters intermesh in ways that become lethal.

K. O. Dahl's stories are propelled by compelling narratives where the final twist is always satisfying.
