Of course Peter Henderson is a character in Tom Clancy Novels. That character uses a alias of "Cassius"

Cassius was a Roman Senator who was involved in teh assassination of Caesar. Coincedence he chose that name?

"Gaius Cassius Longinus (3 October, c. 86 BC – 3 October 42 BC), often referred to as simply Cassius, was a Roman senator and general best known as a leading instigator of the plot to assassinate Julius Caesar on March 15, 44 BC"
