Sneaked about between two points, exhibiting nudity (9)
I believe the answer is:
nakedness
'nudity' is the definition.
(I know that nudity can be written as nakedness)
'sneaked about between two points' is the wordplay.
'two points' means two replacements for 'point'.
'about' indicates an anagram.
'between' means one lot of letters goes inside another.
'point' becomes 'n' (North).
'point' becomes 'S' (South).
'sneaked' is an anagram of 'akednes'.
'n'+'s'='ns'
'akednes' put inside 'ns' is 'NAKEDNESS'.
'exhibiting' is the link.
(Other definitions for nakedness that I've seen before include "Having nothing on" , "being exposed?" , "Nudity" .)
