In dreadful court, getting evasive (8)
I believe the answer is:
Here is my best explanation:
'evasive' is the definition.
('indirect' can be similar in meaning to 'evasive')
'in dreadful court' is the subsidiary indication.
'dreadful' becomes 'dire' ('dire' can be a synonym of 'dreadful').
'court' becomes 'ct'.
'getting' is the link.
(Other definitions for indirect that I've seen before include "In credit, not being straight", "Deviating, not straight", "Oblique, not straight", "Rambling", "Oblique, circuitous", "In credit (anag.)", "Not straight, route say", "Roundabout (route)", "sort of speech" and "Roundabout, circuitous".)
