Way forest officer shows new face (8)
I believe the answer is:
stranger
'new face' is the definition.
(a new face is a stranger)
'way forest officer' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'forest officer' becomes 'ranger' (a ranger might look after a forest).
'st'+'ranger'='STRANGER'
'shows' is the link.
(Other definitions for stranger that I've seen before include "'Weirder, odder (8)'" , "unfamiliar figure" , "Unfamiliar person" , "More rum" , "More odd or wierd" .)
