I don’t usually criticise puzzles. I recognise the need for entry level challenges and appreciate the skill (and time) that is needed to construct even a basic Listener.
However I think this one falls short of the standard required for the Listener.
Adding a few thematic entries to the grid and clueing them by wordplay only does not make it a specialist crossword. Indeed once the penny dropped the thematic clues became much easier to solve. I did spend some time wondering if there is a twist that we have all missed but I don’t think so.
Incidentally 29th November is a significant date in terms of the theme.
