Pulpy goodness

Here is another case of; What the Rory Calhoun is going on here? We have a Depression era Gopher/Isaac aboard the Not-so-Lovable Boat shooting what appears to be a motorcycle cop and whom we can only assume is his partner falling out of a deck chair after dropping a sawed off shotgun. I suppose that somewhere between the covers is the reason for illegally armed motorcycle cops to be aboard some ship with a killer yeoman purser/ bartender but if anyone out there cares to venture a guess we are all ears.
