Many years ago I visited the cemetery associated with the theme, an experience which has always stayed with me. Many thanks to Chalicea for such a lovely puzzle which is so appropriate for today.
Chalicea here - many thanks. I do appreciate the support from solvers and am always delighted when puzzles are enjoyed. The appropriate date for this one was the work of the editor.
Another excellent puzzle from Chalicea, to whom thanks. The analysis of the failure is pretty much spot on - unless you subscribe to the (quite substantial) lobby that says “it’s really all down to JG”.
