Bookseller note: My 11yo asked me why I love reading crime. I gave him this book. He’s a crime reader too, now.

The first book in a wildly popular junior crime series.

Ruby Redfort is a genius code-cracker, a daring detective, and a gadget-laden special agent who just happens to be a 13-year-old girl. She and her slick side-kick butler, Hitch, foil crimes and get into loads of scrapes with evil villains, but they’re always ice-cool in a crisis.
