Harry Rolt is Missing

In the small hours, Harry Rolt and his wife awake to the sounds of someone breaking and entering their house. Harry goes downstairs to confront the burglars, first locking his wife in the bedroom for safety..but then there is the sound of a struggle, and shortly afterwards, a car drives off, and Harry Rolt is missing. But is everything quite as it seems, and why has Harry been kidnapped and by whom? And just who sent the ransom demand for £3 million to the company where Rolt has been working to develop a super-conductor that will work at room temperature?
