Bond brought in to excite the reader (6)
I believe the answer is:
tether
'bond' is the definition.
(I've seen this before)
'brought in to excite the reader' is the wordplay.
'brought in' indicates a hidden word.
'TETHER' is hidden within 'to excite the reader'.
(Other definitions for tether that I've seen before include "Rope keeping animal from straying" , "Hold by a rope" , "Rope restricting animal's movement" , "Leash" , "Rope for confining animal" .)
