Made known criminal's last dealings subject to review (9)
I believe the answer is:
signalled
'review' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can sometimes mean the same thing.
'made known criminal's last dealings subject' is the wordplay.
I cannot really see how this works, but
'made' could be 'led' (leading is a kind of making) and 'led' is found within the answer.
The remaining letters 'signal' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for signalled that I've seen before include "Indicated" , "Gestured, signed" , "Shown" .)
