Walking with Superman: Day 293

There's been a strange rash of fires in and around Meeker, Oklahoma recently, and no one has been able to track down a culprit, or even a motive. Pranks? Accidents? Arson? The local police have been scratching their heads. That is, until one of the repeat fire victims set up a surveillance camera to catch the culprit. What he saw instead was his wife spontaneously combusting, then quickly returning to normal, though not without some collateral damage. And the fiery ailment seems to be spreading, which leaves the Man of Steel to find out why the citizens are flaring up before the whole town burns down!
