Theft of Love
Linda's new boyfriend Pete enjoyed looking at stately homes. She was horrified, when they went to The Old Grange, where a big reenactment weekend was taking place, to find he was planning to steal some of the antiques and expected her to help him. Furiously angry, she found help from a knight in armour, and together they determined to foil the crooks.
