Burley-in-Wharfedale's Martin Walker launched a book of charity quizzes at Otley Waitrose, reports the Wharfedale Observer. 

The book is Mr Walker's second quiz book in aid of the Yorkshire Air Ambulance and anyone who missed the launch will have another chance to see Mr Walker and buy the book at the Saltaire Bookshop on July 9th.

Update: I understand the book can also be ordered from Martin by post, at 109 Main Street, Burley-in-Wharfedale, LS29 7EX
