Haul them out, discovering rakish eavesdropper (5)
I believe the answer is:
heave
'haul' is the definition.
(I've seen this before)
'out discovering rakish eavesdropper' is the wordplay.
'out' indicates a hidden word (I've seen 'out of' mean this).
'HEAVE' is hidden in the letters of 'discovering rakish eavesdropper'.
'them' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for heave that I've seen before include "Tug-of-war cry" , "Pull hard; (sea) swell" , "Move with an effort" , "Produce (a sigh); haul" , "Tug-of-war shout" .)
