It's exactly like "The Phantom Bellman" (4,6)
I believe the answer is:
dead ringer
'phantom bellman' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'it's exactly like' is the wordplay.
'it's exactly' becomes 'dead' (eg in phrases like 'you're dead right').
'like' becomes 'ringer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'dead'+'ringer'='DEAD-RINGER'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for dead ringer that I've seen before include "that might explain silent phone call?" , "one looks very much like another" , "Quasimodo at end of novel?" , "One can do no more changes!" , "Spitting image" .)
