Best friends for life

Dunc Culpepper and Amos Binder are at it again. Some older residents of their town have been bilked by con artists, and the two boys want to look into these crimes.

They meet elderly Betsy Dell, whose nasty nephew Frank gives the boys the creeps. Then they notice some soft dirt in Ms. Dell’s shed, and a shovel. Does Frank have something horrible in store for Dunc and Amos?
