review of dick francis, twice shy, what a book! this is the story of two brothers, jonathan and william derry, starts out with jonathan and a friend, his friend has 3 tapes, he says they are computer programs built to make big money on the racetrack, jonathan takes them, and before he can give them back, his friend is murdered, the story goes on from there, they catch the killer, he goes to prison for 14 years, gbut then is out, and this is where his brother william comes into the story, another great one, Don
