Synopsis of The Rodeo Murder
A party at Lily Rowan’s Park Avenue penthouse includes a roping contest between some cowboy friends, with a silver-trimmed saddle as the prize.
One of the contestants is at a disadvantage when his rope is missing.
When it is found wound more than a dozen times around the neck of the chief backer of the World Series Rodeo, Lily asks Nero Wolfe to sort out the murder.
