End with a shout and a squeak (5,4)
I believe the answer is:
close call
'a squeak' is the definition.
(synonyms)
'end with a shout' is the wordplay.
'end' becomes 'close' (close can mean the closing part of something).
'with' is a charade indicator (letters next to each other).
'a shout' becomes 'call' ('call' can be a synonym of 'shout').
'close'+'call'='CLOSE CALL'
'and' acts as a link.
(Other definitions for close call that I've seen before include "Narrow squeak" , "A near thing" , "One may be disputed in court" , "Lucky escape" , "Narrow decision" .)
