# Forbidden Worlds #71 This issue contains two main stories. "The Iron Brain" depicts a giant robot that breaks free from its controls and begins causing destruction; the story questions what happens when a robot can think independently. The second story follows a doctor investigating a mysterious disease affecting multiple patients, including a boxer named Burke, whose symptoms baffle medical experts until it's revealed the patients are infected with a completely new and unknown strain of microbe, which the government must keep secret to prevent panic.
