RED: 6th Problem

Munitions Buildings, Washington D.C.

 

26 may 1938

 

                   Dear Frank and Solomon,

 

We intercepted this message intended for the
Japanese Embassy in Washington.  We know
the text is in English and the words are separated
by the letter Z.

 

Unfortunately they no longer use the vowel /
consonant separation.

 

Good luck!

 

Wiliam F. Friedman
