Project MK-ZODIAC appreciates that the Bancroft Library at the University of California, Berkeley has permitted these images of "The Red Phantom" by Eloise Keeler to be made available for the general public to view for research purposes.

These images are used with explicit permission from the Bancroft Library at the University of California, Berkeley.

These images may not be distributed beyond this website.

The resolution of these images is 480 x 640 pixels, 72 dots per inch.

As explained in a separate report, the Zodiac may or may not have written a communication mailed from San Rafael, California on July 8, 1974.

There have been various theories about the reason the writer of this communication signed it as "the Red Phantom".

Now there is another possible clue which may be linked to the origin of reference to the Red Phantom.

The Red Phantom circa 1939

"The Red Phantom" is a play which was written in 1939.

Eloise Keller was the author of "The Red Phantom". 

Luke68, a member of the internet forum, discovered that this play had been published as a book in 1939.

The only known copy of this book is in the restricted collection of the Bancroft Library at the University of California, Berkeley.

In November, 2012, two other researchers, Sandy Betts and Zamantha, went to the Bancroft Library at the University of Berkeley, California which granted them permission to obtain copies of this play to be posted on this website only.

Speculation about "The Red Phantom" by Eloise Keeler

This play is a murder mystery which may have been of interest to a killer such as the Zodiac.

There are references to knives, ropes, guns, and torches in the play which may evoke the references to "by fire", "by gun", "by knife", and "by rope" which were included on the Halloween card sent by the Zodiac on October 27, 1970.

Red Hand

This play specifically mentions the "Red Hand" of the killer "clutching a knife".

In connection with the 1966 murder of Cheri Jo Bates which may have been committed by the Zodiac, there was a poem found on a desk in the library at Riverside City College which was signed "rh".


Could "rh" have been inspired as an abbreviation for "Red Hand"?

The message sent from the Red Phantom was mailed from San Rafael on July 8, 1974.

Tamalpais Valley is near Mill Valley.

Eloise Keller was a prolific writer.  She wrote many plays, radio and television scripts, magazine and newspaper articles, etc..

Eloise Keeler was the writer of the Pet Column for the San Francisco Examiner for many years.

It is possible that she knew other contemporary columnists and reporters, such as Herb Caen, Count Marco, and Paul Avery who have been linked to the Zodiac.

Eloise Keeler was a member of the Sierra Club.

A communication which may have been sent by the Zodiac on March 21, 1971 included the words “Sierra Club” for an unknown reason.
