Intelligent System, innit?

[Decrypt room, Maidens Point, Northumbria, 1943]

(Cousin to Enigma, the calculating machine takes up the length of the room and a lot of the width. Commander Millington enters.) 

JUDSON: 

The North Atlantic U-boats have changed ciphers again. That's twice this month. 

MILLINGTON: 

Can we crack them? 

JUDSON: 

Hmm. It may take a few days longer. 

Oh, they're using SIX rotors now instead of five. 

MILLINGTON: 

Get inside The  Nazi Mind, Judson. 

Learn to Think The Way They Think. 

It's the only way to understand their ciphers. 

JUDSON: 

The Machine can do it, if you'd be so kind as to authorise it, sir. 

Thank you.
