26d, as I say, seems to be a name.
27d I'm pretty sure of - I didn't know it, but it is a district in London. 28 d I'm absolutely lost.
33ac seems to be a themed word, and in the list that I've got, there is one that fits the pattern.
Yes, but it seemed to be spelt THYREUS on the Shakespearean lists I found. However, it seems acceptable, so thanks. As with V?L?R?E, I can't make it fully agree with the remainder of the clue though.
