Deserve shows in the Arnolfini (4)
I believe the answer is:
earn
'deserve' is the definition.
(I've seen this before)
'in the arnolfini' is the wordplay.
'in' indicates a hidden word.
'EARN' is hidden within 'the arnolfini'.
'shows' is the link.
(Other definitions for earn that I've seen before include "Gain through labour or work" , "Deserve - merit" , "Get by working" , "Make money" , "Take home" .)
