Eleven-year-old Chris and ten-year olds Skeet and Gail are enthusiastic collectors. With equal avidity they collect animals and rare stamps. When their eccentric neighbor, Mr. Doolittle, appears to be the victim of a stamp theft at the same time their white opossum is stolen, the kids turn to sleuthing. <P>"A lively mystery which imparts much incidental information on the hobby and science of stamp collecting. No gore, just good fun and excitement." – Kirkus
