Comprehensive contract covers termination (8)
I believe the answer is:
detailed
'comprehensive' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for detailed that I've seen before include "Comprehensive" , "Showing attention to fine features" , "Elaborate" , "supplying full particulars" , "Particular" .)
