Gutted we can’t get that Tuesday to work - looked quite fortuitous, given that my wife had one of her friends visiting that afternoon!
Well, I work 3 evenings a week with my job (I’m a church minister), and I have a very young family (2 kids under 2 years old) so me being out in the evenings is pretty costly for my wife.
As for a date after Easter, how about afternoon/evening of Saturday 29th April, in Hampstead Waterstones? Does that work for others? @snoc
