Satisfied — with London's police force? (3)
I believe the answer is:
met
This might be a double definition.
'satisfied' is the first definition.
(as in 'met the conditions of his contract')
'police force?' is the second definition.
(short for Metropolitan Police Service)
'with london's' acts as a link.
This may not be right. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for met that I've seen before include "Bumped into" , "Encountered by chance or arrangement" , "Came across - police in London" , "satisfied" , "Encountered pro tem" .)
