Witness For The Defense is a role-playing module/adventure for FASA's Star Trek: The Role-Playing Game. It was FASA's second adventure book released separately from the box set, one of three (along with "The Vanished" and "Denial of Destiny") published in 1983, and the third of four adventures involving the crew of the USS Enterprise. It was a sequel to TOS episode & Star Trek 4 novelization: The Devil in the Dark.

In this adventure, players assumed the role of the crew of the Enterprise to solve a murder mystery.


The crew of the Enterprise returns to Janus VI, scene of their adventure with the Horta ("The Devil in the Dark"), and finds tragedy. A young miner stands accused of murder and genocide. Will he be convicted by the swift justice of the final frontier, or can Captain Kirk, Mr. Spock and Dr. McCoy find evidence to clear him? And if they do, where is the real killer, and will he strike again — bringing disaster to the mining colony of Janus VI?
