Hostage to public relations? Is one right? (8)
I believe the answer is:
prisoner
'hostage' is the definition.
(thesaurus)
'public relations? is one right?' is the wordplay.
'public relations?' becomes 'pr'.
'right?' becomes 'r' (common abbreviation).
'pr'+'is'+'one'+'r'='PRISONER'
'to' acts as a link.
(Other definitions for prisoner that I've seen before include "One inside" , "Person behind bars" , "Captive, detainee" , "Incarcerated person" , "Captive, incarcerated criminal" .)
