Tow Henry round the bend (4)
I believe the answer is:
haul
'tow' is the definition.
(I've seen this in another clue)
'henry round the bend' is the wordplay.
'henry' becomes 'hal' (short for Henry).
'round' is an insertion indicator.
'the bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'hal' placed around 'u' is 'HAUL'.
(Other definitions for haul that I've seen before include "Pull with effort" , "With effort, draw" , "Drag, with effort" , "Quantity stolen in a robbery" , "Drag; transport in truck" .)
