4 down "Sage Derby, for example, wrapped up by mother" I think Sage Derby is a cheese of some sort. Got "M---t--" last letter(s) poss "um" or "a"
10 across "Henry somewhat bent?" Got --b-t.
15 across "Dialect compromised normal pupil leaving school." Got --r--s-h Presumably last 3 are "sch" as ool leaving school and first bit meaning "compromised"
Any help much appreciated.
