Jack the Ripper - Codes lead to Germany

Motive, organizer, killer are coded in angles, distances, London names. The crime seems to be cleared up. A second serial killer caused damage in and around Chicago. He lived only 5 miles away from the possible Jack the Ripper, whose life from 1841 to 1896 can be well traced on the basis of many documents. Causes for the murders are possibly two conflicts at the beginning of 1888 in southwest Germany.
