Disturbed the pair of wild deer (8)
I believe the answer is:
bothered
'disturbed' is the definition.
(I've seen this before)
'the pair of wild deer' is the wordplay.
'the pair' becomes 'both' (I've seen this in another clue).
'of wild' indicates an anagram (I've seen 'wild' mean this).
'deer' is an anagram of 'ered'.
'both'+'ered'='BOTHERED'
(Other definitions for bothered that I've seen before include "The bored, strangely, can be troubled" , "Took the trouble to do something" , "''Bewitched, ... and bewildered'' (song) (8)" , "Under stress" , "Old song: 'Bewitched, . . . . . . . . and bewildered'" .)
