Rose's place, where Capone hid in a tree! (6)
I believe the answer is:
tralee
'rose's' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
'place where capone hid in a tree' is the wordplay.
'place where' becomes 'tr' (I can't justify this - if you can you should believe this answer much more).
'capone' becomes 'Al' (gangster Al Capone).
'hid in' means to look at the middle letters (I've seen 'hiding in' mean this).
'a tree' becomes 'neem' (neem is a kind of tree).
The middle letters of 'neem' are 'ee'.
'tr'+'al'+'ee'='TRALEE'
Can you help me to learn more?
(Other definitions for tralee that I've seen before include "'The Rose of ------': song/film title featuring a town in County Kerry, Ireland" , "Kerry town of Roses" .)
