Bottom left corner is giving me problems. if 20a is ornament (knick-knack) which fits with 14d caution; what on earth is 21d actual R???. 23 a clue is male deer which I presume is either stag or buck but I simply can't get anything to fit. 16a which uses the A from ornament is sly ??A??? It could be crafty if the male deer ended in t. Help would be appreciated before I start chewing the carpet! Thanks.
