The Rare Stamp Mystery, (Paperback)

There was plenty of excitement at the Red Barn that day. The Red Barn was a restaurant run by Skeet Macdonald's parents. A rare stamp has been stolen from the home of a nearby collector. Skeet and his friends think this loss might tie in with a theft a short time ago at the Macdonald farm. So the three children set out to solve the case.

This is how another entertaining Mary Adrian mystery begins. And like the others, into its plot is woven a good deal of interesting information -- this time about rare stamps and stamp collecting. There is also an appendix of terms and a list of books for any young reader who would like to know more about philately or stamp collecting.
