Maureen Cathryn Harriet "Cats" Falck (11 July 1953 – date of death uncertain, between November 1984 and May 1985) was a Swedish television journalist who, together with her friend Lena Gräns, disappeared in Stockholm in 1984 while she was investigating a scandal involving the smuggling of weapons from Sweden to communist states in Eastern Europe. The dead bodies of Falck and Gräns were later found at the bottom of the Hammarby Canal in Stockholm. The deaths remain unsolved but later reports claim that they were assassinated in a state-sponsored operation by agents from East Germany.
