The Little Lady of the Big House (1915) was Jack London's last novel to be published during his lifetime.
The story concerns a love triangle. The protagonist Dick Forrest is a rancher with a poetic streak (his "acorn song" recalls London's play "The Acorn Planters"). His wife Paula is a vivacious athletic and sexually self-aware woman who falls in love with Evan Graham an old friend of her husband. Unable to choose between the two men she wounds herself mortally with a rifle in what her husband is certain is a suicide.
