The city's answer, to flood its nether vaults, turns out to threaten a global catastrophe that only Pendergast and company, aided by Navy SEALS, can avert. Forays by these principals into the kingdom of the Mole People (underground homeless), plus some forensic breakthroughs, point to a race of mini-Mbwun at work in an escalating series of savage killings that incite the city's upper crust to civil disobedience. They're soon joined by the novels' Sherlock Holmes figure, the irresistibly cool Special Agent Pendergast of the FBI. The corpses are sent to the museum's lab for analysis, which brings a number of returnees from Relic-burly homicide cop Vincent D'Agosta, anthropologist Margo Green, New York Post crime reporter Bill Smithback-to the case. The sequel, set 18 months after Mbwun was destroyed, opens with a police diver finding the headless bodies of two people apparently killed by underground cannibals. In the earlier novel, Mbwun, a ferocious creature that seemed part reptile, part human, rampaged through the museum killing people. The netherworld of New York City-its subways, aqueducts, sewers and the homeless who inhabit them-proves as shuddery a setting for the authors' latest scientific monster mash as the American Museum of Natural History did for their bestselling Relic, to which this is the sequel.
