I've got three left to do but am stuck fast.
1D Criticise opening book of OT revealing early practice in Eden (6)
I want to answer "Nudism" but if that is right why is it right?
9A Nag, or variety of one (3)
d(if nudism is right)-n
13a Even couples in bathhouses like this (4)
Only words I can fit in are "skis" and "ekes" but can't understand why either should fit.
