11-year-old Dawn Buckle embarks on a highly dangerous mission in the world of espionage!
Rustygate Primary School does not teach espionage and sleuthing, so when Dawn Buckle is asked by S.H.H. (Strictly Hush Hush) to become a highly trained spy with P.S.S.T (Pursuit of Scheming Spies and Traitors) she feels rather at a disadvantage. But showing an incredible ability and very quick thinking she soon finds herself caught up in an incredible adventure to unearth the wicked 'spy-gone-bad' Murdo Meek.
Can Dawn piece together all the parts of the incredible riddle before Murdo does away with his hostage? Can she outwit this master criminal while at the same keeping out of harm's way?
