The Crisscross Shadow

About “The Crisscross Shadow”

When a man selling leather goods door-to-door steals the key to their detective father's file cabinet, Frank and Joe Hardy set out to track him down. An odd mark on a key case sold to their mother leads the teen-age sleuths to an Indian village, whose chief begs their help recovering a deed and tribal possessions buried by his father before his death, marked only by a crisscross shadow cast at a certain full moon. Written by Franklin W. Dixon, it was published in 1953.
