Ackroyd's first novel outlines many of the themes that he has explored since in his prolific output. At the centre of things, the city of London, the interweaving of past and present, high literary content with reference to Dickens, and a ragbag collection of eccentric, unlikeable characters who wander through the story in rather haphazard style.
Just what the book is about is open to several interpretations, but at least at 167 pages it is blissfully short - unlike much of Ackroyd's later outpourings. As a novelist, his books are quite hard work to read, and ideas jump around all over the place - a style of writing that was certainly established here in this opening novel.
Critical acclaim abounds on the paperback edition - frankly these days as a first novel it probably wouldn't get accepted.
