I was able to take up residence inside fiction by virtue of a scheme entitled the Character Exchange Programme. Owing to a spate of bored and disgruntled bookpeople escaping from their novels and becoming what we called 'PageRunners', the authorities set up the scheme to allow characters a change of scenery. In any year there are close to ten thousand exchanges, few of which result in any major plot or dialogue infringements — the reader rarely suspects anything at all. Since I was from the real world and not actually a character at all, the Bellman and Miss Havisham had agreed to let me live inside the BookWorld in exchange for helping out at Jurisfiction — at least as long as my pregnancy would allow.

The choice of book for my self-enforced exile had not been arbitrary; when Miss Havisham asked me in which novel I would care to reside I had thought long and hard. Robinson Crusoe would have been ideal considering the climate but there was no one female to exchange with. I could have gone to Pride and Prejudice but I wasn't wild about high collars, bonnets, corsets — and delicate manners. No, to avoid any complications and reduce the possibility of having to move, I had decided to make my home in a book of such dubious and uneven quality that publication and my subsequent enforced ejection were unlikely in the extreme. I found just such a book deep within the Well of Lost Plots among failed attempts at prose and half-finished epics of such dazzling ineptness that they would never see the light of day. The book was a dreary crime thriller set in Reading entitled Caversham Heights. I had planned to stay there for only a year but it didn't work out that way. Plans with me are like De Floss novels — try as you might, you never know quite how they are going to turn out.

I read my way into Caversham Heights.
