Suspect golfer's taking in a quiet game (8)
I believe the answer is:
leapfrog
'game' is the definition.
(I know that leapfrog is a type of child\\u0027s game)
'suspect golfer's taking in a quiet' is the wordplay.
'suspect' indicates an anagram (a suspicious or unusual spelling).
'taking in' is an insertion indicator.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'golfer' anagrammed gives 'lefrog'.
'a'+'p'='ap'
'lefrog' enclosing 'ap' is 'LEAPFROG'.
(Other definitions for leapfrog that I've seen before include "Advance by jumps" , "Playground game" , "bound over" , "Children's game of jumping over each other" , "Game in which players vault over each other" .)
