Reliquary (novel)

Reliquary is a novel by Douglas Preston and Lincoln Child first published in 1997. It is the sequel to Relic and the second in the series of novels fan-named the Agent Pendergast series.

It has been eighteen months since the infamous Museum Beast Murders at the New York Natural History Museum. Most of the players have moved on with their lives and left that horrible time as a distant nightmare. They are all dragged back into the horror when two skeletons are dug out of the river with chillingly familiar wounds, including missing heads.

Tropes used in Reliquary (novel) include:

Absurdly Spacious Sewer: Justified in that all the tunnels and spaces below Manhattan actually exist, even with the liberties of placement, names and exact size taken by the authors. It's estimated that there's enough room down there that several thousand people make it their homes.
A God Am I: Frock, as Pendergast notes, was setting himself up to be one.

He wanted to be God - his God, the God of evolution.

- A much more benign example is Mephisto, considering himself king of the underworld.

Chekhov's Gun/Chekhov's Classroom: A SEAL Team member explains to Snow how to use the M16's grenade launcher.

Crazy Homeless People: Mephisto and his underground community.
Dressing as the Enemy: Vaguely. Pendergast and D'Agosta infiltrate the homeless community disguised as hobos to try and get any leads on the murders.

Gone Horribly Wrong: Kawakita prematurely begins taking the modified reovirus and suffers horrible deformity and an allergy to vitamin D. When he reaches out to Dr. Frock for help, it gets him killed for his trouble.
Gonk: The wrinklers, who resemble naked mole rats with reptilian eyes.
Hand Cannon: Inverted when Pendergast recons the tunnels again: he brings along an incredibly small pistol with a round that could "send a bullet through an elephant. Lengthwise."

Heroic Sacrifice: Mephisto takes out Frock and a mass of wrinklers by blowing himself up with a landmine. He saves the others and ensures the safety of his community.

Title Drop: Pendergast calls the reconstructed skull hut in the Crystal Pavilion a reliquary.
