Colleague of Spooner's strengthened cry (9)
I believe the answer is:
bedfellow
'colleague' is the definition.
(both can mean an associate)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bedfellow that I've seen before include "Person slept with" , "Mate" , "Colleague" , "Close associate or partner" , "Partner (in the boudoir?)" .)
