Discworld series, published in 2002. The working title for this book was
The Nature of the Beast, but this was discarded when Frances Fyfield published a book with exactly that title in the UK in late 2001. The protagonist of the novel is Sir Samuel Vimes, commander of the Ankh-Morpork City Watch. A five-part radio adaptation of the novel was broadcast on BBC Radio 4 from February 27 2008 - it featured Philip Jackson as Sam Vimes and Carl Prekopp as young Sam, and referenced the similar theme of a policeman unexpectedly being sent back in time from the series
Life on Mars.
