Book Sartre edited (6)
I believe the answer is:
arrest
'book' is the definition.
(I know that book can be written as arrest)
'sartre edited' is the wordplay.
'edited' indicates anagramming the letters.
'sartre' with letters rearranged gives 'ARREST'.
(Other definitions for arrest that I've seen before include "Take into legal custody" , "Catch" , "Take into custody as police do" , "Apprehend; detain" , "Stop - take into custody" .)
