The faces of evil
Rumours and accusations are reaching Stargate Command, and nothing is making sense. When SG-1 is met with fear and loathing on a peaceful world, and Master Bra'tac lays allegations of war crimes at their feet, they know they must investigate.
But the investigation leads the team into a deadly assault and it's only when a second Daniel Jackson stumbles through the Stargate, begging for help, that the truth begins to emerge. Because this Daniel Jackson is the product of a rogue NID operation that spans the reaches of the galaxy, and the tale he has to tell is truly shocking.
Facing a cunning and ruthless enemy, SG-1 must confront and triumph over their own capacity for cruelty and violence in order to save the SGC - and themselves...

Jack had never heard Bra'tac express mistrust of the Tauri since those very earliest days. The hair rose on the back of his neck. "Bra'tac, what the hell are you talking about?"
"I am speaking of the massacre which occurred on Eshet yesterday - the massacre led by your team in pursuit of technology owned by the people of that world."
