Press into service in City (8)
I believe the answer is:
shanghai
I believe this is a double definition.
'press into service' is the first definition.
(I've seen this before)
'city' is the second definition.
(Shanghai is an example)
'in' is the link.
(Other definitions for shanghai that I've seen before include "Force to join ship's crew, Chinese port" , "Dragoon" , "Kidnap - Asian city" , "Darts player might be pleased with this" , "Press-gang" .)
