If you're a true fan of Life on Mars, this book is a must.
The book is written like a text book by Gene Hunt and this is Chris Skelton's "copy". The book is complete with answers (DCI Hunt's and DC Skelton's), various caricatures and girl's phone numbers (with a brief description), coffee stains, blood splatters and various other smudges you don't really want to dwell on what they might be. It also has the scoring of a drinking competition between the characters of the show (written in the hand of DC Skelton).
The book is written with the same wit as the character DCI Hunt employs in both 'Life on Mars' and 'Ashes to Ashes'.
It's humorous and witty and I would definitely recommend it.
