Boycott toys making comeback in dangerous locality (5,4)
I believe the answer is:
black spot
'dangerous locality' is the definition.
The definition suggests a singular noun which matches the answer.
'boycott toys making comeback' is the wordplay.
'boycott' becomes 'black' (black list).
'toys' becomes 'tops' (top is a kind of toy).
'making comeback' says the letters should be written in reverse.
'tops' in reverse letter order is 'spot'.
'black'+'spot'='BLACK SPOT'
'in' is the link.
Can you help me to learn more?
(Other definitions for black spot that I've seen before include "accident site" , "Trouble for rambler, say" , "disease?" , "Place noted for terrible accidents" , "Place on road where accidents often occur" .)
