Cloak and dagger thriller, with a sheaf of valuable notes on jet performance the goal- and a fortune in thousand dollar notes complicating the set-up. Hero- Scott Elliott, the test pilot who held a secret locked in his mind and was ordered complete rest and seclusion as a way to release the spring; heroine- the mystery blonde, Nagle Stafford, who knows too much- and too little- for her own health and peace of mind. Ample scope for action, with mystery piled on mystery- and a bit better written than some under this imprint.
