Agent Pendergast investigates a series of strange murders and rumours of a murderous beast in the New York Museum of Natural History. The New York Museum of Natural History is built over a subterranean labyrinth of neglected specimen vaults, unmapped drainage tunnels and long-forgotten catacombs. And there's something down there. When the mutilated bodies of two young boys are discovered deep within the museum's bowels, Lieutenant Vincent D'Agosta of the NYPD fears a homicidal maniac may be at large . FBI agent Aloysius X.L. Pendergast believes they may be facing something much worse . As the death toll mounts, and with the opening of the museum's new 'Superstition' exhibition just days away, the two men must work together to prevent a massacre .
