Lord turning up in Hotel Bonaparte (5)
I believe the answer is:
noble
'lord' is the definition.
(I know that lord can be written as noble)
'turning up in hotel bonaparte' is the wordplay.
'turning up' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'elbon' can be found hidden inside 'hotel bonaparte'.
'elbon' in reverse letter order is 'NOBLE'.
(Other definitions for noble that I've seen before include "Honourable ? aristocratic" , "Former gold coin" , "Titled peer of the realm" , "Of high rank or birth" , "Person of high rank" .)
