An excellent challenge I thought, took a couple of sessions. Picked up the ‘cypher’ in the first row fairly early on but it was only towards the end that I realised how it continues through the grid, an excellent piece of construction. That certainly helped with the last couple to drop in. Thanks to Picaroon.
I note the online entry simply requires the answers to clues which doesn’t really prove that you’ve been able to complete the grid, which is a bit odd…
