Rodney ran in that direction (6)
I believe the answer is:
yonder
'in that direction' is the definition.
(I've seen this before)
'rodney ran' is the wordplay.
'ran' is an anagram indicator (letters have run around).
'rodney' anagrammed gives 'YONDER'.
(Other definitions for yonder that I've seen before include "Over there, of old." , "In that direction" , "Distant but within sight" , "that one" , "Over there (poetic)" .)
