Inspector Morse creator Colin Dexter has joined a list of celebrities to contribute to a special charity brain teaser.
The Imperial Cancer Research Fund quiz has been launched to raise 25,000.
Mr Dexter, of Oxford, is one of 12 famous people to write a question for the teaser, which costs 10 to take part.
The winner of the 144-question quiz will be rewarded with a weekend for two in Paris and a 100 book token.
Other celebrities who have taken part include Tony Blair and dancer Darcy Bussell.
Anyone who would like to try the quiz, which comes in a festive booklet and covers categories from astronomy to zoology, should contact the ICRF hotline on 020 7269 3106.
