The Dog That Never Was by Stephen Lister

Good.

A pre-publication critic has said:
"Quite early in the book I regarded Bonzo, who plays a central role, as such an absurdity that I almost decided to read no further. Then second thoughts prevailed. There were times when Bonzo appeared to me (like his master, Archie) as the product of a disordered imagination, but there were others when I was convinced, not only that I could see him, but hear his irritatingly shrill bark. Now . . . well now I just don't know."
To this Stephen Lister's only comment, succinct if not grammatical, was: "Nor me neither." Which suggests that there have been moments of doubt in the author's mind.
