The apparent suicide of an American journalist in 1970s Stockholm propels Persson's ponderous English debut, the first of a trilogy. The victim, John Krassner, was working on a book detailing the exploits of his uncle, Col. John Buchanan, an OSS agent in the years following WWII and Buchanan's ties to a now high-ranking Swedish politician known by the code name "Pilgrim." The Swedish secret police, who were hearing chatter concerning threats to the Swedish prime minister, had been keeping an eye on Krassner at the time of his death. Curious about Krassner after discovering a personal connection to the case, police superintendent Lars Johansson begins his own inquiry and unearths more than he bargained for, including disparate pieces of a vast political conspiracy.
