I struggled with this one, not sure why since others have found it easier and I've enjoyed the trickier ones over the last few weeks. Still, each to their own I suppose. Nevertheless I have managed a completed grid after fortuitously spotting the thematic help, and have the lines and name. Clever endgame. Nice.
There are a few clues I just can't suss out, though I'm sure I have their answers ok, and interestingly they all seem to be ones no one has yet asked about! If anyone could give me a few little hints it would set my mind at rest as I don't like loose ends...!
