Enigma: 16th problem,

Station X, Hut 6                            January 29, 1940

 

 

Dear Mrs Martin,

 

You are joining the Netz room today. Dawson has
taught you how to use stacking sheets to find the
key to the day. Now is the time to use your
knowledge.

 

Please bring the following extract from the Blist
with you, containing only the females of the day. I
also give you the first message for review.

 

I wish you good luck!

 

Gordon Welchman
