Angel of Vengeance

Preston & Child continue their #1 bestselling series featuring FBI Special Agent Pendergast and Constance Greene as they take a final stand against New York's deadliest serial killer: Pendergast's own ancestor and Constance's greatest enemy. A desperate bargain is broken as Constance Greene confronts Manhattan's most dangerous serial killer, Enoch Leng, bartering for her sister's life but is betrayed and turned away empty-handed, incandescent with rage. A clever trap is set. Unknown to Leng, Pendergast's brother, Diogenes, appears unexpectedly, offering to help for mysterious reasons of his own. Disguised as a cleric, Diogenes establishes himself in New York's notorious Five Points slum, manipulating events like a chess master, watching Leng's every move and awaiting his own chance to strike. A vengeful angel will not be deterred. Meanwhile, as Pendergast focuses on saving the unstable Constance in her fanatical quest for vengeance, she strikes out on her own to rescue her beloved siblings from a tragic fate and take savage retribution on Leng. But Leng is one step ahead and has a surprise for them all.
