Found this hard going, not because of the theme, which was comparatively easy to identify, but because this is an Enigmatist puzzle and that meant some intricate wordplay at times. Enigmatist upsets many forum posters whenever he appears during the daily GW crosswords but is at home in the Prize and Genius slots.
Even when the clues are relatively straightforward, the identity of the setter means that I jump at shadows by trying to think of the most fringe definitions and convoluted possible parsing.
