What an absolute stinker! Chock-full of deletions and obscurities, a heavy reliance on general knowledge, and a couple of dodgy definitions thrown in for good measure.
Please can anyone help with these two?
5a: Fifty maybe touching base in interval (8)
S?M?T?N?
Looks like SEMITONE (= interval, in music). I get that FIFTY could be SEMI-TON (half a hundred), but where does the final E come from?
48d: Film director hides old letter relating to Flower of Hades (7)
L?T?E?N
Looks like LETHEAN (= relating to the LETHE, the river of the Underworld). The film director is David LEAN, but can anyone explain the "old letter"?
