Bill and Fred?

Katie Lynch and her family go to Walburley Hall to meet the new owners and are astonished to find that Bill and Fred are ladies - sisters who have spent all their lives in East Africa. More surprises are revealed as Katie gets to know them : Fred can fix cars no matter what their age and is a wizard at snooker. Bill can organise anything. The sisters desperately need funds to repair the old house, and the prize money offered by the Grand Knockdown Charity Snooker Challenge seems like the ideal opportunity. If Fred can beat Flash Fagan, maybe the Hall can be saved.
