Wrong.
The bishop was eager to restore his position, but he did not
instigate Silas to *kill*.
Aringarosa had longed for Silas to be part of his glorious plan.
Last night, however, Aringarosa had received a call from Bezu
Fache, questioning the bishop about his apparent connection to a
nun who had been murdered in Saint-Sulpice. Aringarosa realized the
evening had taken a horrifying turn. News of the four additional
murders transformed his horror to anguish. Silas, what have you
done! Unable to reach the Teacher, the bishop knew he had been cut
loose. Used. The only way to stop the horrific chain of events he
had helped put in motion was to confess everything to Fache, and
from that moment on, Aringarosa and Fache had been racing to catch
up with Silas before the Teacher
persuaded him to kill again.
