This is a delightful story for all ages, especially children 9 years old and up. Will and Stacie are bicycle riding, amateur detectives who have been solving crimes since they meet in 1957, age 12 years old. The detective duo found an unconscious woman on a picnic table under a pavilion, near the entrance to the Colony. The Raindrop mystery appears in the middle of thieves, mobsters, and counterfeiters. The coal mine is the least of the problems.
