Leader of pack seen in two lakes? (5)
I believe the answer is:
akela
'leader of pack' is the definition.
(I've seen this before)
'in two lakes?' is the wordplay.
'two lakes?' means two replacements for 'lake'.
'in' says the answer is hidden in the clue.
'AKELA' can be found hidden inside 'lake lake'.
'seen' is the link.
(Other definitions for akela that I've seen before include "pack-leader" , "Leader of pack of Cub Scouts - she-wolf in "The Jungle Book"" , "Adult Cub Scout leader" , "Cub Scouts adult leader" , "Cub Scout pack leader" .)
