Despicable information (7)
I believe the answer is:
lowdown
I believe this is a double definition.
'despicable' is the first definition.
(synonyms)
'information' is the second definition.
(I've seen this before)
(Other definitions for lowdown that I've seen before include "confidential information" , "Inside information - mean" , "base" , "Dope" , "news" .)
