Almost there, but worried about one and stuck with another...
24a Woman providing a feast perhaps after noon (6) u-d-n-. The best I can come up with is UNDONE, but it is a ropy answer at best.
53a Earth-shattering event is taking place in Kent area, close to Chatham. S-I-M. Well the M comes from Chatham, but I need a 4 letter word for the Kent area, and the definition seems to be an earth shattering event.
Any thoughts? As ever, thanks in advance.
