garble - you're lucky only to be stuck in the NE ... I think 4d is a word for "dropping by" and needs to be 19 22d into a word for doing well. Haven't a clue about 5d - or 3,6,10, 14, 15 or 21. I am assuming 19 22 only uses letters within a small range of the original - but have consulted websites and different versions seem to work different ways so am still in the dark about what exactly the setter means.
