NANCYDREW BABY SITTER BURGLARIES

Nancy is searching for a house thief who's robbing river heights blind.....

Three houses in River Heights have been burglarized, and the police can find only one connection: Juanita Puentes has baby-sat in all three. Nancy's convinced that the baby-sitter is being set up, and she's determined to prove it. But the only way to clear Juanita's name is to catch the real burglar in the act.

The key to the case is a security system that has failed at each house- systems installed by Juanita's boyfriend. As the evidence mounts an investigation that leads to a series of dangerous encounters.... with an angry Doberman, a mystery assailant, and a life-threatening kidnapper!
