Can anyone make any suggestions on my last 4 clues:
12a More than one sore old swindler's left out E??ER?
15a Cut old rule of descent EU???IL
22a Morag's to cure HER sudden fit E??I?T
18d Poet's grotto right next to square column (6)
BUT (i) there may be one letter wrong in the definition part of the clue
AND (ii) the answer may be 1or even 2 letters shorter than indicated!
Should anyone wish to take a look at the grid, clues & complete instructions (pretty complicated as always) they're to be found at:
alumni.cam.ac.uk/cam
There's no hurry, but after a week I really am exhausted!
