Got into bed with a novel (8)
I believe the answer is:
obtained
'got' is the definition.
('obtain' can be a synonym of 'get')
'into bed with a novel' is the wordplay.
'with' says to put letters next to each other.
'novel' indicates anagramming the letters.
'into'+'bed'='intobed'
'intobed' after 'a' is 'aintobed'.
'aintobed' anagrammed gives 'OBTAINED'.
(Other definitions for obtained that I've seen before include "Got, procured" , "Into a bed (anag.)" , "Came into possession of" , "Acquired" , "Got something" .)
