Can’t go out (too cold), can’t do gardening work (too cold), can’t blog (too cold) – but I can rustle up another fiendish crossword in my mittens.  I promise it will be the last (for a while).  Hints for those unaccustomed to cryptic crosswords:  don’t read the clues literally, they are full of red herrings to distract you from the definition part which directly suggests the answer and the cryptic part which tells you how to get that answer; ignore punctuation put there to confuse or make the clue grammatical, but don’t ignore punctuation put there to suggest ambiguity or levity; and the definitions are not always straightforward – lateral thinking and familiarity with this blog and my twisted mind would help.
