First of clues missed out? Puck's hard to find (7)
I believe the answer is:
elusive
'hard to find' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
(Other definitions for elusive that I've seen before include "Difficult to find or catch" , "Not easy to pin down" , "Slippery, hard to catch" , "Vile Sue, not easy to find" , "Hard to find" .)
