Malice long disheartened editor in Times (8)

'malice' is the definition.
(bitchery is a kind of malice)

'long disheartened editor in times' is the wordplay.
'long' becomes 'itch' (I've seen this before).
'disheartened' means to remove the middle letters.
'in' means one lot of letters goes inside another.
'times' becomes 'by' (I've seen this in other clues).
'editor' with its middle taken out is 'er'.
'itch'+'er'='itcher'
'itcher' placed into 'by' is 'BITCHERY'.
