Doctor has odd brown beds (5)
I believe the answer is:
bones
'doctor' is the definition.
(I've seen this before)
'odd brown beds' is the wordplay.
'odd' indicates alternate letters.
'brown'+'beds'='brownbeds'
The alternate letters of 'brownbeds' are 'BONES'.
'has' is the link.
(Other definitions for bones that I've seen before include "Nickname for a doctor" , "Elements of a skeleton" , "... skeletons, perhaps" , "Components of skeletons" , "Tibia, fibula etc" .)
