22) The Moving Toyshop, by Edmund Crispin
Got this off Bookmooch, after reading ‘s review (in which she explores its literary antecedence of Doctor Who), and greatly enjoyed it. It is a murder mystery set in Oxford in 1938, solved by Gervase Fen, professor of poetry; the plot is convoluted and utterly implausible, but it is written with immense verve, energy and humour. Anyone who knows Oxford will appreciate the attention to local detail. (Anyone expecting a sort of prehistoric Inspector Morse will be disappointed.)

It is important that we know where we come from, because if you do not know where you come from, then you don’t know where you are, and if you don’t know where you are, you don’t know where you’re going. And if you don’t know where you’re going, you’re probably going wrong.
I’d forgotten about that. Goes for personal history too.
