Run into detective, blocking awkward ambush (9)
I believe the answer is:
intercept
'ambush' is the definition.
(thesaurus)
'run into detective blocking awkward' is the wordplay.
I cannot really see how this works, but
'run' could be 'r' (cricket abbreviation) and 'r' is found within the answer.
'into' could be 'in' and 'in' is present in the answer.
'detective' could be 'tec' (tec is short for detective) and 'tec' is found in the remaining letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for intercept that I've seen before include "Obstruct to prevent reaching a destination" , "Seize in transit" , "Stop in transit" , "Arrest" , "Stop a moving object" .)
