Jan Guillou

Jan Oskar Sverre Lucien Henri Guillou (born 17 January 1944) is a French-Swedish author, journalist and convicted spy. Guillou has been accused by some commentators of being an agent of the KGB. Guillou's fame in Sweden was established during his time as an investigative journalist, most notably in 1973 when he and co-reporter Peter Bratt exposed a secret, immoral and illegal intelligence organization in Sweden, Informationsbyrån (IB). He is still active within journalism as a column writer for the Swedish evening tabloid Aftonbladet. Among his books are a series of spy fiction novels about a spy named Carl Hamilton, and a trilogy of historical fiction novels about a Knight Templar, Arn Magnusson. He is the owner of one of the largest publishing companies in Sweden, Piratförlaget, together with his wife, publisher Ann-Marie Skarp, and Liza Marklund.
