An infamous thief hides in the countryside—where cunning Cornelia Van Gorder picks up the trail—in a mystery from the #1 New York Times–bestselling author.
 For months, the city has lived in fear of the Bat. A master criminal hindered by neither scruple nor fear, he has stolen over one million dollars and left at least six men dead. The police are helpless, the newspapers know nothing—even the key figures of the city’s underworld have no clue as to the identity of the Bat. He is a living embodiment of death itself, and he is coming to the countryside.
There, he will encounter the only person who can stop him: adventurous sixty-five-year-old spinster Cornelia Van Gorder. Last in a long line of New York society royalty, Cornelia has found old age to be a bore, and is hungry for a bit of adventure. She’s going to find it—in a lonely old country house where every shadow could be the Bat.
