Robber’s drunken manner with crew (10)

I believe the answer is:

highwayman

'robber's' is the definition.
(thesaurus)

'drunken manner with crew' is the wordplay.
'drunken' becomes 'high' (high can informally mean drunk).
'manner' becomes 'way' (synonyms).
'with' means one lot of letters go next to another.
'crew' becomes 'man' (both can mean to staff or operate something).
'high'+'way'+'man'='HIGHWAYMAN'

(Another definition for highwayman that I've seen is " 1 across, for example".)

I've seen this clue in The Times.
