Read chapter two, “The First 3,000 Years.”  Pay close attention to pages 99 – 105 for how to break simple substitution ciphers.  Use the step-by-step description on these pages to break the following cipher:

Q EQKB EQRB Z STFR, ZESTLI.
Z STFR VQIC HBY EQGL,
LCTHI PHBLLBL ZFY NQY CZQH.
-LQFZ IVHFBH

You may assume the above is English text.
Takes about 1.5 hours to read.
