Felix Leech

From Memory Alpha, the free Star Trek reference.

Felix Leech was one of Cyrus Redblock's employees in the Dixon Hill stories. He was well known to historians such as Whalen.

In 2364, when the USS Enterprise-D's holodecks were malfunctioning, the senior staff was held at gunpoint by a hologram of Felix Leech. Leech shot the historian Whalen and was chased out of Dixon Hill's office by Captain Picard. He returned with the hologram of Cyrus Redblock. When the holodecks were restored, both Leech and Redblock attempted to exit, but were immediately dematerialized. (TNG: "The Big Goodbye")

Felix Leech was played by actor Harvey Jason.
