At the destroyed horse ranch, Hastings looks round at the request of the sheriff, and once again finds pools of the strange, thick liquid. He decides an analysis could solve the mystery, so he takes samples and flies them to the university in Phoenix. The substance is determined to be tarantula venom, but in such a quantity that only a monster arachnid could produce. After being shown a film demonstrating the predatory ferocity of a normal tarantula, he calls Dr. Deemer, but is told by Steve that he is sick in bed. Deemer suddenly appears behind her and the phone call is cut dead. Hastings immediately flies back to Desert Rock.
