this be a strange and lukewarm chiller that arguably for the first time in the movie have a corpse tell the story of her mysterious death by way of flashback from a lab in cold storage . this be also the only movie that bela lugosi play in that be release in color . the mysterious green mask that keep appear in the window do fit into the weird story line . albeit this 65 minute mystery or drama be more odd than horror . beside lugosi and very familiar face show up in the cast represent george zucco and roland varno and nat pendleton be aid by molly lamont and gladys blake .
