Twice Shy

SUMMARY: School teacher Jonathan Derry is unwittingly in possession of some computer tapes containing a bookie-breaking betting system. Fortunately, Jonathan is a crack shot with a rifle, a talent which comes in very handy when two gunmen burst into his homelooking for the tapes. Fourteen years later, Jonathan's brother William is threatened by one of the self-same thugs. He still wants the tapes - and his revenge. But, unlike his brother, William decides to play a shrewder, waiting game.
