Death at the Sanatorium

Jónasson follows up Reykjavik with a meticulously plotted whodunit worthy of Agatha Christie, whose work he translates into Icelandic. In 2012 Reykjavik, 30-something Helgi Reykadi is finishing his criminology dissertation on an unsolved homicide in a tuberculosis sanatorium turned research facility. Flashbacks fill in details about Helgi’s subject: in 1983, someone tortured and murdered Ysra, a nurse at the facility, and a few days later the institution’s director suffered a suspicious fall from the balcony. Police arrested the building’s janitor on a false tip from nurse Tinna—who threw the janitor under the bus to distract from her own suspicious behavior—then let him go. After that, the case went cold. In 2012, Tinna turns up dead, so Helgi tracks down her and Ysra’s old coworkers in hopes of solving both murders. When his interview subjects turn out to be strangely tight-lipped, he launches into a twisty investigation that culminates in a volcanic finale. With scrupulously fair-play plotting, Helgi’s tumultuous relationship with his live-in girlfriend as an emotional anchor, and a worthy payoff, this is another winner from Jónasson. Readers will be rapt. (Sept.)
