Suspicious soldier without papers? (8)
I believe the answer is:
paranoid
'suspicious' is the definition.
(I've seen this before)
'soldier without papers?' is the wordplay.
'soldier' becomes 'para' (short for paratrouper).
'without' becomes 'no'.
'papers?' becomes 'ID' (identification papers).
'para'+'no'+'id'='PARANOID'
(Other definitions for paranoid that I've seen before include "mental disorder" , "Suffering delusions; road pain (anag.)" , "Excessively suspicious" , "Distrustful" , "Irrationally obsessed by fear etc" .)
