Nathan Filer still does the odd Sunday shift as a registered mental health nurse, although they may well become less frequent after his debut novel – originally the subject of an 11-publisher bidding war – was on Monday night named winner of one of the UK's leading book prizes.

The comedian Jo Brand has called The Shock of the Fall "one of the best books about mental illness" and judges for the Costa book awards said it was a novel "so good it will make you feel a better person".
It was named as one of five category winners for the Costas and will go forward to compete for the overall book of the year prize, to be decided later this month.
Filer, 32, won in the best first novel category for a story about a young man's dramatic descent into mental illness, although the author said he hopes it is about more than that.
