Mounted police meeting a member about going from place to place (7)
I believe the answer is:
nomadic
'going from place to place' is the definition.
(nomadic means travelling from place to place)
'mounted police meeting a member' is the wordplay.
'mounted' says the letters should be written in reverse.
'police' becomes 'CID' (abbreviation for Criminal Investigation Department).
'meeting' says to put letters next to each other.
'member' becomes 'mon' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cid'+'a'+'mon'='cidamon'
'cidamon' in reverse letter order is 'NOMADIC'.
'about' is the link.
(Other definitions for nomadic that I've seen before include "Migratory" , "always moving?" , "Peripatetic" , "Not settled" , "Perhaps unsettling" .)
