Hi, Irisheyes,

My kids liked these:

Mordecai Richler, Jacob Two-Two's First Spy Case;


Janice Eaton Kilby, The Master Detective Handbook: Help Our Detectives Use Gadgets and Super Sleuthing Skills to Solve the Mystery and Catch the Crooks.

There are, of course, lots of kid detective (as opposed to spy) books: would she be interested in Nancy Drew or Trixie Belden or that sort of thing? Or in a more spy-ish vein, the MT Anderson ones are quite fun (Whales on Stilts, Clue of the Linoleum Lederhosen, Agent Q, etc.). My boys also really liked John Fardell's Seven Professors books--kind of James Bond for kids.

A historical spy story my kids liked was "Popinjay Stairs" by Geoffrey Trease (set in the reign of Charles II; Samuel Pepys is one of the characters! Fun and very well-researched.)

Hope that helps a bit!
