How would you go about killing someone who was never really alive – not in the usual sense of the word? Mr Teatime (pronounced teh-ah-tim-eh) knows exactly how he'd do it.

As philosophical textbooks go, this is a stonker. What is the nature of belief? How do beliefs interact with reality? How do they colour our view of reality?

As for zingy and/or pithy moments … this books got them in spades.
“The phrase 'Someone ought to do something' was not, by itself, a helpful one. People who used it never added the rider 'and that someone is me'.”

As a novel, though, this one falls a bit short. The plot meanders a bit too much for my liking.

Very good, but not Sir Pterry's finest.
