Caravaggio - I went with the idea of Philip. In the end I just focused on the "cloth" part of the clue.
Finally managed 5d, which was amusing, once I had shifted into the right thought pattern. 15a was also, in my opinion a toughie but well set. Crossword finally completed but a much tougher one this week!
Philip you should be ok tomorrow but remember make no sudden moves to spook the natives. Remember what happened to Captain Cook! A bunch of shiny trinkets will go down well. Any problems and I'm sure that you will e-mail us all next week. Finally, the currency market here is unpredictable - so haggle for the best conversion rate on the day!
Seriosly, the Grosvenor Museum is worth a visit - have fun.
Must stop writing these mini essays.
