Sandra’s former chief of security, Solomon Hart, was sent skyward to investigate, but only given 24 hours aboard the Delta One to make his case. Though it was officially ruled an accident, he suspects there’s more to this story than meets the eye. In order to solve this cold case murder mystery game you’ll need to find 3 separate clues.
