This is one of the most energetic of Holt’s many mysteries featuring Hanne Wilhelmsen. Events move at a fast pace, paralleled with Hanne’s partner’s decline and death from cancer. Cecilie has been an important part of Hanne’s life for several novels and, oddly enough, I read the sequel to this novel in the past and remembered Hanne’s slow recovery from Cecilie’s demise. This mystery also more strongly features the massive Billy T., Hanne’s work partner and devoted friend. In fact, the smoldering love he has for Hanne breaks out even though he decides to get married after having a baby with Tone-Marie. (#5!! Though with different mothers!) In the meantime, Hanne works on an involved case that seems to turn on a murder committed by a dead man (the “Dead Joker” of the title.) A “joker” in the novel is loosely defined as something floating in water, much as we might use the term “dead head.” The accused perp is the Chief Public Prosecutor, Sigurd Halvosrud. The victim is his wife, Doris, whose headless body is found in their home with Sigurd’s prints all over the body, a convenient sword and other signs that make it 98% sure that he’s guilty. Hanne, as usual, has reservations; something does not add up. She and Billy T. go on as if Halvorsrud is NOT the guilty party and in the process they get into a web of intrigue that involves pedophilic behavior and worse. Then there is another beheading and things get even murkier as Halvorsrud was just released before the killing and it looks like he has struck again. Hanne again refuses to go with conventional wisdom and keeps at it. All this time, Cecilie has been dying from cancer, though the process is so fast that Hanne can hardly keep up. Both she and Billy T. spend many sleepless hours pursuing the case and Cecilie’s deterioration. Hanne is at her most feminine in this novel. Nearing forty, she is more concerned with her appearance than in other Wilhelmsen mysteries and her relationship with Billy T. deepens and turns in unexpected directions. Oddly enough, as is the custom in Nordic Noir, characters are seldom referred to by their first names alone: Hanne is always “Hanne Wilhelmsen” yet we never learn T’s last name! Hanne continues throughout to momentarily consider retiring, but there are other novels featuring her so she stays on the job for the nonce, at least ! Another solid performance from Holt and a fine Nordic Noir entry.
