The Secret of Shadow Ranch is the 10th computer game in the series and is based on the 5th book of the Nancy Drew series The Secret of Shadow Ranch. In this adventure, Nancy Drew has been invited to the eponymous ranch, which belongs to relatives of her friends, Bess Marvin and George Fayne. At Shadow Ranch, a ghostly glowing horse has been seen riding up to the fence, rearing up, and galloping away, vanishing into the night. Every time this happens, a detrimental event occurs right after. This game takes place in Arizona. This is the first Nancy Drew game with a smaller interface menu.
