Morning all. Bit of a mixed bag today, but enjoyed it overall. COD 12a and 11d. Took me ages to realise 26a was an anagram of Transience - I was convinced that that was the definition! I also missed the rhyming pair. Couldn't have got 13d without help from the forum. Likewise, 19d.
I'm clearly being very dense, because despite the tips on here, I still can't get 22d. Is the single letter for France F, or something else? If it is, then the only word I can think of if fake, which I can't parse! My original answer (lies) is also un-parsable!
