Answer :
When he "divided
his rope in half," it does not
follow
that he
cut it into two parts, each half the original length of the
rope.
No
doubt he simply untwisted the strands, and so divided it into two
ropes,
each of the original length, but onehalf the thickness.
He would thus
be
able to tie the two together and make a rope nearly twice the original
length, with which it is quite conceivable that he made good his escape
from the dungeon.
