Play about a redhead in Helen's place (4)
I believe the answer is:
troy
'helen's place' is the definition.
I can't judge whether this defines the answer.
'play about a redhead' is the wordplay.
'play' becomes 'toy' (synonyms).
'about' indicates putting letters inside.
'a redhead' becomes 'r' (head letter of 'red').
'toy' going around 'r' is 'TROY'.
'in' is the link.
Can you help me to learn more?
(Other definitions for troy that I've seen before include "The pound - had twelve ounces, ancient city" , "System of weights used for precious metals" , "City besieged by Greeks to rescue Helen" , "Iliad siege city" , "Ancient city besieged to free beautiful Helen" .)
