Ifor, that was magnificent. Thank you. A lot of very chewy clues and one or two gimmes to keep my spirits up. With an almost full grid I made the mistake of pondering the end game while I made the tea, without the preamble and grid to hand. So I went down two rabbit holes: one, an obscure gothic novel that gets a mention in Northanger Abbey; and, two, a novel in the “A Staircase in Surrey” sequence. But a look at the grid once dinner was done and clarity dawned. A corker!
