When they hear about a ring of international spies on the loose in the city, the brother-sister detective team knows they've got a mystery to solve. Little things like being haunted by Civil War ghosts and the sudden growth of vegetation in Sean's hair won't distract Bloodhounds, Inc. from uncovering the truth about a stolen top-secret helicopter And the lesson they learn-that real men and women love Jesus--will stick with them forever.
