For readers who prefer their pulp in smaller bites: the anthology!
For the girls.
And for the boys.

Some backstory: this image is the "colorized" version of the original black and white that was collected by the FBI back in the inter-war period when a couple of curious agents were poking about and adding things to their files, marked "U" because they were unsolved, or - unexplained.
There's more about these things on the Artifacts Page. How the hell Vantage Pointe Books got the original from the FBI is as much a mystery as what happened after the photograph was taken.
