'retired from here?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'old police sergeant involved in church work' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'police sergeant' becomes 'ps'.
'involved in' is an insertion indicator.
'church' becomes 'ch' (common abbreviation).
'work' becomes 'op' (abbreviation for opus).
'o'+'ps'='ops'
'ops' placed into 'ch' is 'copsh'.
'copsh'+'op'='COP SHOP'
