In Scotland's valleys, Elizabeth's heart picks up (6)
I believe the answer is:
gleans
'picks up' is the definition.
(to glean something is to learn or pick it up)
'in scotland's valleys elizabeth's heart' is the wordplay.
'in' indicates putting letters inside.
'scotland's valleys' becomes 'glens' (term for valleys in Scotland).
'heart' indicates the central letters.
The middle of 'elizabeth' is 'a'.
'glens' placed around 'a' is 'GLEANS'.
(Other definitions for gleans that I've seen before include "Picks up (information)" , "Angles (anag.)" , "Harvests, reaps" , "Harvests, gathers" , "Garners" .)
