Top Of The Form

Self-styled 'Professor' Ronnie Fortescue is a bookmaker's worst nightmare: an habitual gambler who has devised a system for picking horse-race winners that appears to actually work!

When a group of bookies' heavies set to put an end to his endeavour, Fortescue makes a break for it. They give chase, but he ducks off track - and unwittingly straight into the grounds of a small boys' school, currently troubled, in threat of closure by the government, and in search of a new headmaster.
