The Cabinet of Curiosities (Pendergast, Book 3)

In one of NPR's 100 Best Thrillers Ever, FBI agent Pendergast discovers thirty-six murdered bodies in a New York City charnel house . . . and now, more than a century later, a killer strikes again.
In an ancient tunnel underneath New York City a charnel house is discovered.

Inside are thirty-six bodies -- all murdered and mutilated more than a century ago.

While FBI agent Pendergast investigates the old crimes, identical killings start to terrorize the city.

The nightmare has begun.

Again.
