Run after James Hadley (5)
I believe the answer is:
chase
'run after' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for chase that I've seen before include "Hound" , "trail" , "Pursuit" , "Hurry" , "Pursue, run after" .)
