BOISE, Idaho — Patrick F. McManus, a prolific writer best known for his humor columns in fishing and hunting magazines who also wrote mystery novels and one-man comedy plays, has died. He was 84. McManus died Wednesday evening at a nursing facility where he lived in Spokane, where he had been in declining health, Tim Behrens, who performed the one-man plays, said Friday. “He was a warm man, he was a good man, he was a funny man,” Behrens said.
