The Cipher Code Book

I have located some interesting evidence that Andrews had left that I don't think has been reported here or any other printed articles. (1) The following statement comes from a police report and was reported in a San Francisco newspaper.

"Everything that could lead to a positive identification had been destroyed or taken away by Brush and the woman. He left, however, what apparently a telegraph cipher code, a private code, and written in pencil in a vest pocket memorandum book, which is accepted as evidence that he is one of a gang."

So possibly this code was used to send telegrams in code and also to make anagrams. Sending a telegram in code requires words that have some meaning that can be spoken and not just a bunch of scrambled letters, otherwise it would have drawn suspicion. This is a pattern that Andrews used; scrambled names an aliases such as Nulda Petrie=Edna Little etc.

If there was a way to search old telegrams there could be some more clues to who Erdnase really was.

Also if Andrews used codes he may have a secret message in Expert!

Notes: (1) Whaley may have found this info but I don't think it was examined to any degree in TMWWE. Gardner was not aware of this information at all.
The codes were very common in those days. Here is a link to Pinkerton's http://www.pimall.com/nais/pivintage/telegraphcipher.html

All these facts about Andrews are strictly speculation and theories, which are fun to explore without drawing a definitive conclusion.

It is just interesting that this private code has never been discussed since it was found in his personal articles.
