The Danger On Shadow Mountain Double Detectives

This title is the fourth in the "Double Detectives" series. It is suitable for children aged 8 to 12 years old. A trip to the Rockies to snowboard? Cool. Hanging out with champion snowboarders on the mountain? Really awesome! When twins Cody and Otis Carson, along with their cousin Rae, join their dad at the Shadow Mountain Lodge, they're expecting a relaxed vacation. But after a series of strange and dangerous "accidents" aimed at two rival snowboarders, the twins set out to discover what's going on - before someone gets killed.
