Abby and the Notorious Neighbor — Ann M. Martin

America's favorite baby-sitters are detectives, too!

Abby is sick. Not sick enough to sleep all the time, but not well enough to do much. So she watches a lot of TV and she stares out the window. Before long, she's really bored. Then one afternoon she realizes that a face she often sees through her window looks exactly like a face she's just seen on TV. But it isn't the face of a celebrity -- it's a wanted criminal! Now Abby's convinced that her neighbor is a thief in hiding.

It's going to take some clever sleuthing to gather proof that will convince the police. Abby's not sure she can do it. But she is sure of one thing. She's not bored anymore. She's terrified!
