For the benefit of readers from outside the UK, Hugh Fearnley-Whittingstall is the real name of a real TV chef. Although he hasn’t actually written a book called “Cooking With Roadkill”, it’s exactly the sort of thing he would do. Here’s a quote from a Guardian article about him, via his wikipedia page:

…it got him a commission to make his first Channel 4 series, A Cook on the Wild Side, in which he drove around Britain picking up roadkill and eating the hedgerows, which earned him his nickname of Hugh Fearlessly-Eatsitall
