The Hunt for the Death Valley Germans (2012) (otherhand.org)

This is an excellent real life detective adventure vividly recounted by the author.

To those familiar with his work, did he retire from writing? There was no update after Bill Ewasko was found.

This was published quite a few years ago, possibly 2012, the last date mentioned near the end. I remember reading it a while back. I clicked this link hoping there was an update.
