Sammy Keyes is back, with the same spunk and verve as in past titles, and her boyfriend Casey to boot. Still sneaking into the retirement community where she lives secretly with her Gran, there's a new crime-fighter in town: Justice Jack. How is it that he manages to stop so many crimes-in-action? And why, if he is, is crime on the rise? Meanwhile, where has Gran's bossy neighbor Mrs. Wedgewood gone? Well-paced and featuring many of the favorite characters of past books, this will have great appeal to tween readers. Recommended.(216) ( )
