Here's a little something different for you for Friday. This is the tale of a cowboy, riding alone in Mexico, who unexpectedly faces a deadly choice. Should he give "el tiro de gracia" — the mercy shot?
This story is actually dated after 1923. "What's up with that?" you wonder. Well, it's simple. Back in the day, the author or copyright holder had to renew the copyright on a story after a certain period of years in order to keep it. This copyright was not renewed, for whatever reason, and has therefore fallen into the public domain.
I found this story through pulpgen.com, a wonderful resource for sampling public domain "pulp fiction". (As opposed to the fiction found in more expensive magazines that used more expensive paper — the "glossies".) But you can also find it on blackmask.com.
