This is billed (front cover) as "A Joe Pike Novel". Don't worry, Elvis fans: he's here, he does important stuff too, despite his rocky recovery from the horrors in the previous book. But the interesting stuff, character-wise is Pike.
In a different previous book, Pike promised a future favor to Jon Stone: Stone would offer Pike a gig,
and Pike would have to accept it. That promise comes due here. The FBI has a witness to the presence and
activity of a wanted terrorist. That witness is the very spoiled, insanely rich heiress
sorry, Larkin Connor Barkley. The normal witness-protection procedures ain't working. Squads of Ecuadorian
gangsters keep showing up at the "safe" houses, apparently trying to kill her.
Worse, once Pike takes over, Ecuadorian gangsters show up at his safe house, and it's all Pike can do to kill a few of them, and take off. Obviously there's a mole somewhere, but who?
The best defense is a good offense, and Elvis and Joe take it upon themselves to discover the truth about what Larkin saw, and why people want to kill her for it. Larkin is a lot to handle, but she's never met anyone like Pike before. Diligent detective work soon determines that one of the FBI guys is lying to them; does that mean he's the mole? It's not safe to assume that.
As usual, a suspenseful and action-packed climax.
