- Plot: Banker Hubert Kingery invites fellow officers to his hunting lodge only to announce that one of them has forged critical company documents. Later, he is found shot to death, apparently at his own hand. His daughter, Gwen, is the only one who does not believe it was suicide. She asks help from aunt's nurse, Sarah, who suggests her detective boyfriend, Lance, for the task. When he arrives, he's not sure the death was not a suicide after all. But as he investigates the few available clues, he tries to sort fact from fallacy.
