Summary

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.

Review

"A lively mystery which imparts much incidental information on the hobby and science of stamp collecting. No gore, just good fun and excitement." -- Kirkus
