William in business like that, Peter? (8)
I believe the answer is:
costello
'peter?' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'william in business like that' is the wordplay.
'william' becomes 'tell' (I've seen this before).
'in' is an insertion indicator.
'business' becomes 'co' (short for company).
'like that' becomes 'so' (I've seen this in other clues).
'co'+'so'='coso'
'tell' inserted inside 'coso' is 'COSTELLO'.
Can you help me to learn more?
(Other definitions for costello that I've seen before include "Elvis -, British singer, songwriter" , "Rock singer" .)
