Dawn and the Halloween Mystery — Ann M. Martin

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

Halloween is coming, and Dawn and her friends in the We Love Kids Club are almost as excited as the kids they baby-sit for. Then, just before the big night, a masked robber holds up a store in Dawn's neighborhood -- and Dawn witnesses the getaway!

Even with Dawn's description, the police can't catch the robber, so Palo City's parents set a curfew until the thief is caught.

But that means trick-or-treating is off -- and that means a lot of disappointed kids. Unless Dawn and the WLKC can catch the robber themselves....
