Late caller gets double (4,6)
I believe the answer is:
dead ringer
'double' is the definition.
(I've seen this before)
'late caller' is the wordplay.
'late' becomes 'dead' (similar in meaning).
'caller' becomes 'ringer' (I can't explain this - if you can you should give a lot more credence to this answer).
'dead'+'ringer'='DEAD RINGER'
'gets' is the link.
Can you help me to learn more?
(Other definitions for dead ringer that I've seen before include "Lookalike" , "Likeness" , "Someone who looks identical to another (slang)" , "double" , "One can do no more changes!" .)
