“Inter-what?” When advertising executive Conrad Maddox returns from a redeye flight and finds a mysterious locker key waiting in his rental car, he discovers a briefcase loaded with guns and money. Several hours later, his entire life tumbles down a rabbit hole when he meets Dandine, owner of the case and former contract assassin for a shadowy organization called Norco, which is now out to nail both of them.

“Internecine” means conflict, mutual destruction, and slaughter—or, as Dandine tells Conrad, they are now inadvertently at play in a field of “terrorism, counter-assassination, military coups, dirty tricks, Watergate, spy vs. spy, murky secret organizations, that sort of thing.” A world in which being innocent can’t save you, the police can’t help you, and your only hope of getting out alive is to risk unheard-of dangers against opponents with nearly unlimited power. To free themselves from the spider web of black ops, murder, madness and betrayal, Dandine and Conrad must delve ever-deeper into the spiraling, dangerous maze that is Norco, where everyone seems to be in on the most lethal of games…except you.
