In the Lake of the Woods (1994) is a novel by the American author Tim O'Brien. In the Lake of the Woods follows the struggle of Vietnam veteran John Wade trying to deal with a recently failed campaign for the United States Senate. After moving to Lake of the Woods County, Minnesota, John discovers one morning that his wife, Kathy, is missing. Through flashbacks to John's childhood, college years, and war experiences, as well as testimony and evidence from affected characters, the novel provides several hypotheses for Kathy's disappearance, without resolving the question.
It was adapted as a made-for-TV movie in 1996.
