““The more I thought about Jocelyn's theory, the less bizarre it seemed. Yes, there were things about it that were absolutely cuckoo - Mrs Chang's Mexican double and so forth - but still, overall the idea was not without its merits. It made a strange sort of sense to me, on an intuitive, metaphorical level. Being in here - going crazy - it did feel like your life had been hijacked in some inexplicable way. It did feel like a parallel universe, separated from the real one by only the flimsiest of partitions.””
