Funny ending to Freddie Starr's book (6)
I believe the answer is:
arrest
'book' is the definition.
(I know that book can be written as arrest)
'funny ending to freddie starr's' is the wordplay.
'funny' indicates an anagram.
'ending' indicates one should take the final letters.
The final letter of 'freddie' is 'e'.
'e'+'starr'='estarr'
'estarr' anagrammed gives 'ARREST'.
(Other definitions for arrest that I've seen before include "Stop - detain" , "Sartre (anag) -- check" , "Collar" , "Catch" , "Stop (on suspicion)" .)
