An old, wealthy, and intelligent man, a longtime donor to the Democratic Party, and husband to the much younger Ruth Rasmussen, Claude Rasmussen is an ambiguous character for much of In the Lake of the Woods. It is Claude who invites John to stay on his property for a few weeks after John loses the primary election, effectively ending his political career. Later, when Kathy disappears, Claude offers John his company and help, but often seems to be withholding outright sympathy. Claude tells John that he can’t say he voted for him, but also can’t say he didn’t vote for him—it’s this kind of ambiguous “support” that characterizes his relationship with John for most of the book. Toward the end, however, Claude reveals that he’s highly sympathetic to John’s experiences as a soldier in Vietnam, and understands that John has been expressing his sadness over Kathy’s disappearance in unusual ways. He leaves John the keys to a boat, allowing him to flee to Canada before John can become bogged down in a police investigation.
