Mercer Boys

The Mercer Boys series consists of 10 books, action-adventure mysteries published between 1929 and 1932. They appeal to the same young audience as the Hardy Boys or Nancy Drew. Capwell Wyckoff went on to write many other novels for young readers, including the Mystery Hunters series.

The Mercer Boys head to Southern California to search for buried Spanish gold. The Mercer Boys on a Treasure Hunt is the third book in the popular boys' mystery-adventure series by Capwell Wyckoff, originally published between 1929 and 1933.

The summer camp of Woodcrest Military Institute was always an exciting event to the Mercer boys and Terry Mackson. But when the cadets camped near Rustling Ridge, the boys ran into a series of startling occurrences: a horse stampede, a mysterious fire, the disappearance of a little girl, and most frightening of all, the Ghost of Rustling Ridge, who seemed determined to drive the cadets away. Don and Jim, along with Terry, were appointed to the camp's Ghost Patrol, and how they solved the mystery of the ghost makes one of the most exciting adventures in the Mercer Boys Series.
