Read chapter fourteen, “Duel in the Ether: The Axis.”  Pay attention to pages 440 to 443 for a description of how to apply the difference method on encicode to deduce the placode.  The rest of the chapter is just history of axis WWII cipher and breaks.  One can see how the SYKO system worked by reading to pages 463-464.  Takes about 2 hours to read.
