Tradesman possibly welcomed by the three blind mice? (8)
I believe the answer is:
retailer
'tradesman' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for retailer that I've seen before include "Merchant" , "story-teller" , "Purveyor" , "Seller (of goods)" , "Tradesman" .)
