From hill, Eve retrieved young hare (7)
I believe the answer is:
leveret
'young hare' is the definition.
(I've seen this before)
'from hill eve retrieved' is the wordplay.
'from' indicates the answer is hidden within the clue.
'LEVERET' can be found hidden inside 'hill eve retrieved'.
(Other definitions for leveret that I've seen before include "Young three dn" , "Young runner" , "First-year hare" , "Fast runner, potentially" , "hare about in spring" .)
