End with a shout and a squeak (5,4)
I believe the answer is:
close call
'a squeak' is the definition.
('close call' can be a synonym of 'squeak')
'end with a shout' is the wordplay.
'end' becomes 'close' (closing is a kind of ending**).
'with' means one lot of letters go next to another.
'a shout' becomes 'call' ('call' can be a synonym of 'shout').
'close'+'call'='CLOSE CALL'
'and' is the 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" .)
