Dr Crippen perhaps losing love for right inmate (8)
I believe the answer is:
'inmate' is the definition.
(I know that inmate can be written as prisoner)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for prisoner that I've seen before include "Senior PR (anag) - one in detention" , "Inmate doing porridge" , "The ---, cult 60s TV series" , "Hostage" , "Captive, detainee" .)
