Hoodlums steal a worthless painting, and Kent Murdock wants to know whyA collection of valuable Italian paintings finds its way to Boston, placed in the care of Professor Andrade. Before passing them to a museum, the professor hires newspaper photographer Kent Murdock to document them. On his way to the assignment, Murdock is stopped by a gunman named Erloff, who steals the reporter’s identification—and pays his own visit to the professor. But Erloff is not after the expensive stuff. He cracks Andrade on the skull and leaves with nothing but a worthless painting of a green-hued Venus. Murdock is perplexed. Why all the trouble for an ugly piece of modern art? But the jade Venus holds a terrible secret—and blood will flow before it comes to light.
