I have talked elsewhere about how it began as a single short story that spawned a few sequels. It was only after I had written five linked stories that I realised I was actually writing a novel and that the stories were chapters in a longer work.
The Pilgrim's Regress is a sort of 'Don Quixotic' picaresque adventure, although it's not strictly speaking a set of unrelated episodes as there is an overall arc. The novel is one of my favourites among all my books but I know it is far too metafictional to be commercially successful. No matter! I had huge enjoyment writing it.
There is something about the Spanish landscape that lends itself very well to picaresque wanderings; but in fact the hero of this novel travels to Africa and India as well as across Persia.
The book is available on all Amazon outlets including Amazon UK.
