Mystery of the Night Explorers

City kid Randy is introduced to the wonders of nature by his country cousin, Jimmy, and eventually begins to love life in the country. The two boys build Hidden Lookout, a treehouse, and begin keeping watch on night animals. During the day, they follow clues to try to discover a long-hidden treasure.

"A quietly pleasant summer story set around the routine treasure hunt provides as well the unusual habits of common country ''critters.''" -- Kirkus
