Ruby Redfort's not your average kid. She's super-smart, always ice-cool, not to mention a gadget-laden secret agent with a talent for breaking codes. And she can keep her mouth shut . . . can't she? Ruby and her butler, Hitch, work for an undercover crime-busting organization, where break-ins, daring rescues, and life-OR-death situations are all in a day's work. But always remember Rule #1: You can never be completely sure what might happen next.
