Dotty, Brody and Nye discovered going after Eve, Tom, Dick and Harry (9)
I believe the answer is:
everybody
'tom dick and harry' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'dotty brody and nye discovered going after eve' is the wordplay.
'dotty' indicates anagramming the letters (a mad or 'dotty' version of the letters).
'and' is a charade indicator (letters next to each other).
'discovered' means to look at the middle letters (dis-covered - outer letters removed).
'going after' is a charade indicator (letters next to each other).
The centre of 'nye' is 'y'.
'brody' put after 'y' is 'ybrody'.
'ybrody' with letters rearranged gives 'rybody'.
'rybody' put after 'eve' is 'EVERYBODY'.
Can you help me to learn more?
(Other definitions for everybody that I've seen before include "One and all" , "All persons" , "All and sundry" , "people generally?" .)
