When a customer asks for John Carrawack I should know they mean Jack Kerouac right?
And Margaret Stoppard is of course Miriam. Tori turned out to be Torey. Sink is Schlink.
I couldn’t think who the reclusive Irish woman who died was, but I did know “The kite book”, “Something with a sun in the title”, “The diary of Miss Jones”, “the Indian woman who wrote a novel that is a film” and lots more.

I have started working in a bookshop recently, the Amnesty one in the lanes. We don’t get many stupid questions at all, although I did get one “trilogy of books with a writer that sounds Japanese”. Apparently she’d been in before and the person in the shop that time had actually known what it was, but she’d forgotten.
Good for people to know.
