Member of the force working on a lead? (6,3)
I believe the answer is:
police dog
'member of the force working on a lead?' is the definition.
(cryptic definition - leash not clue)
'member of the force' is the wordplay.
'member' becomes 'policed' (I can't justify this - if you can you should give a lot more credence to this answer).
'of' becomes 'o''.
'the force' becomes 'G' (short for gravity).
'policed'+'o'+'g'='POLICE DOG'
(Other definitions for police dog that I've seen before include "busy helper" , "one taking lead in war on crime" , "maybe I do a lot of sniffing" , "Drug hunter" , "Officer's co-worker" .)
