Chapter from Mann's title - Doctor?? (10)
I believe the answer is:
instalment
'chapter' is the definition.
(I've seen this before)
'mann's title doctor??' is the wordplay.
'doctor??' indicates anagramming the letters (I've seen 'doctor' mean this).
'manns'+'title'='mannstitle'
'mannstitle' anagrammed gives 'INSTALMENT'.
'from' is the link.
(Other definitions for instalment that I've seen before include "episode" , "One of a series of partial payments" , "Chapter" , "Payment of part of debt" , "part of serial" .)
