Relieved to find I'm not the only one having trouble with some of these clues and the parsing thereof.
I got three on the first read through and then steady progress until I ground to a halt with seven left, mostly in the south east quarter, but including 18d and 19d. I've just taken a break to get the washing in - it was very cold, 4.2C according to my weather station - and finished it off in the dryer. Many not fully parsed. I agree with Chris about lots of the clues and disagree with Rocky about Vlad being fair. Thanks for the hints above, though I don't understand how you halve a letter for 2d. Nor can I think of a plural word for money.
Please can I have a hint for 27ac and 21d and I will go away and see if I can make progress on the remaining answers. Meanwhile my FOI was 12ac followed by two other anagrams.
