Swedish author Tursten's third Huss mystery opens with a compelling setup: Detective Inspector Huss and her team find Jacob Schyttelius, a divorced teacher, shot dead in his isolated cottage, his computer monitor marked with a bloody Satanic symbol. They visit his parents, Sten and Elsa, only to find them dead as well and with the same markings on their computer. Huss focuses her inquiry on Sten, a minister who had been investigating a local Satanist movement. The case takes Inspector Huss from Goteborg to London and eventually leads to a shocking climax.
