Grand book stolen from dope? (5)
I believe the answer is:
noble
'grand' is the definition.
('noble' can be similar in meaning to 'grand')
'book stolen from dope?' is the wordplay.
'book' becomes 'b'.
'stolen from' is a deletion indicator.
'dope?' becomes 'nobble' (both can mean to drug a racehorse).
'nobble' with 'b' removed is 'NOBLE'.
(Other definitions for noble that I've seen before include "Having high moral character" , "Magnificent old coin" , "Maybe count" , "with a title?" , "Dignified" .)
