I guess I'm missing something really obvious here as no one else has mentioned it, but can anyone parse 13D -- the answer seems to contain a bit of an anagram (of 'I'm the') but otherwise I'm flummoxed.
Yep -- there's probably a PhD thesis kicking about somewhere on why the brain suddenly clicks into gear a second too late! By the way, does anyone else think 26A should have been set as 3,1,6 rather than 3,7? I'm not sure what the convention is.
Help the needy! I need 18down - Infernal horrible poetry. 'When Half Becomes One' I have an idea which is an American exclamation but if so I certainly can't parse it. Thanks people.
