Lying in the obvious place (4)
I believe the answer is:
abed
'lying' is the definition.
(lying abed or in bed)
'obvious place' is the wordplay.
'obvious' becomes 'a' (I can't explain this - if you can you should give a lot more credence to this answer).
'place' becomes 'bed' (bedding is a kind of placing).
'a'+'bed'='ABED'
'in the' is the link.
Can you help me to learn more?
(Other definitions for abed that I've seen before include "at rest" , "Not yet up (archaic)" , "in his hammock awaiting Santa?" , "not exactly stirring" , "Bead (anag.)" .)
