Evil intent of maiden, a girl in wonderland (6)
I believe the answer is:
malice
'evil intent' is the definition.
(I've seen this in another clue)
'maiden a girl in wonderland' is the wordplay.
'maiden' becomes 'm' (cricket abbreviation).
'girl in wonderland' becomes 'lice' (I can't justify this - if you can you should believe this answer much more).
'm'+'a'+'lice'='MALICE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for malice that I've seen before include "Spite - desire to hurt" , "Hatred" , "Desire to harm others, may be aforethought" , "evil intent" , "'Ill-will, spite (6)'" .)
