A fast-paced, enjoyable entry in the long-running Three Mesqueteers Western series, Heroes of the Saddle featured the three cowboy pals promising to look after Peggy Bell, the little daughter of mortally wounded rodeo champ Montana. Legal technicalities, however, halt the adoption proceeding and Stony, Rusty, and Rico can only watch as the little girl is placed in the county orphanage.
