AN OXFORD tour guide has dreamed up a half-term treat for families who want to explore Oxford - a book in the form of a treasure hunt.

Felicity Tholstrup, who lives in Northmoor Road, said the idea for the book came after she was asked to organise a treasure hunt last year to raise money for the Q Trust for Muscular Dystrophy.

"Some 226 children and their families took part, and many of them asked me to create something similar as a book," she said. "I have launched it in time for school half-term."

A series of clues lead people on a quest for shrunken heads, underground windows, priceless jewels and dinosaur footprints.

Ms Tholstrup added: "It will tap into your imagination as you learn about pioneering aeronauts, scientists and others who lived here in the past."

A typical clue reads: "On westernmost window of a college on the High, a monk with no manners looks down from the sky.

"Some of those faces may give you a fright, But what is he doing that is really not polite?"

The book also contains a map and a concise history of Oxford. Quite the best Oxford Quest costs £5 at Blackwell's and other city bookshops.
