by the aid of his friends, doth contrive to
escape from the Tower, and make his way from London to a place of
safety, he must surely die.

"Sir Walter is now confined within the square tower next after passing
through the Tower of St. Thomas, which, thou no doubt knowest, is that
one into which the "Traitor's Gate" doth lead.

"If thou wilt but turn to the enclosure in this letter thine eyes shall
behold an order, signed by his Majesty, King Richard, that shall obtain
for the bearer admittance to and exit from any part of the Tower.
However, this cannot give unto thee power to take forth a prisoner with
thee. That must be done at thine own risk, and in the manner
following:--

"There is but one keeper in attendance on Sir Walter. Him thou must
master, and in a quiet manner. Take then from his belt the keys that
do depend therefrom. Leave the keeper in such a condition as shall
secure thee of his quietness. The aforesaid keys will give unto you an
exit into the space before the square tower. When ye have reached
this, turn to your left, and again will the keys open the gate in this
wall with which ye shall soon be confronted. Then, looking to your
right, ye shall behold the wall that doth separate the yard from the
watery moat. Approach this with the exercise of great caution and ye
shall then observe an opening where the wall is now being repaired by
workmen, in the day time, and at night it is guarded by a single
soldier, armed with a pole-axe. Ye must quiet this man by whatever
means best serving. But over and above all else, the neglect of which
advice must be the ruin of ye both, permit him to make not any noise;
for the utterance of but one word by him shall be the signal for his
fellows to come to his assistance; in which case escape is impossible.

"When the sentry shall have been removed the moat must be crossed as
best ye can. The water therein is now both fresh and high, and
therefore it will not be difficult for ye to descend into it and swim
across. This ye must do in a most careful manner, that the guard be
not disturbed by the noise of splashing water.

"At a point directly opposite to the place where the wall is now being
repaired ye shall find a ladder made of ropes and cross pieces, placed
there for your especial use and privilege.

"By these same means ye may assist your friend to freedom, and that,
without great risk; providing that the aforesaid instructions be
followed with exact
