Transfer duke speedily (4,4,4)

Ross

I believe the answer is:

hand over fist

'speedily' is the definition.
(thesaurus)

'transfer duke' is the wordplay.
'transfer' becomes 'handover' (I've seen this before).
'duke' becomes 'fist' (put up your dukes).
'handover'+'fist'='HAND OVER FIST'

(Other definitions for hand over fist that I've seen before include "In large amounts and swiftly" , "Rapid rate of money-making" , "(E.g. make money) very easily" , "(Make, lose or spend money) very rapidly" , "(Gain) rapidly" .)

I've seen this clue in The Telegraph.
