Man one to be skinned soon (4)
I believe the answer is:
anon
'soon' is the definition.
(I've seen this before)
'man one to be skinned' is the wordplay.
'man one' becomes 'non' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'be' becomes 'yaw' (yawing is a kind of being).
'skinned' means to look at the middle letters.
The centre of 'yaw' is 'a'.
'non' after 'a' is 'ANON'.
(Other definitions for anon that I've seen before include "Immediately" , "In the near future" , "devoid of credit" , "Soon, precious stone" , "soon to be written" .)
