This quiz has been prepared by Mastermind contestant Ken Owen – who many of you will have just seen answering questions on the Roy Grace novels as his chosen Specialist Subject. If you missed it you can watch it again online on iPlayer.

The winner will received a signed copy of Not Dead Yet, before the publication date of June 7th! And in addition will receive a magnum of fine Champagne. The four runners up will also each receive a signed copy of Not Dead Yet before the publication date! So five of you will get the chance to read the book way before anyone else!
