Dear Mrs
Driscoll
We have intercept another message from naval
japonese attaché. Fortunately we know its
beginning :
TOP z SECRET z STOP z FROM z ADMIRALTY z
TO z SECRETARY z OF z DEFENSE z
We know too they still use the separation of vowels
and consonants.
We hope you will be able to solve it.
Admiral William D. Leahy,
