Huntsman’s cry produced by friend in front of this house (5-2)
I believe the answer is:
tally-ho
'huntsman's cry' is the definition.
(I've seen this before)
'friend in front of this house' is the wordplay.
'friend' becomes 'ally' (an ally is a friend or supporter).
'in' is an insertion indicator.
'front of' says to take the initial letters.
'house' becomes 'ho' (abbreviation for house).
The first letter of 'this' is 't'.
't'+'ho'='tho'
'ally' put inside 'tho' is 'TALLY-HO'.
'produced by' acts as a link.
(Other definitions for tally-ho that I've seen before include "Come on, hounds!" , "Hunter's cry" , "Huntsperson's cry" , "Cry of the huntsman pursuing the fox" , "Fox-hunting cry" .)
