Angel Fire

by Lisa Unger

Published 1 January 2002
The childhood murder of Lydia Strong’s mother has turned her into a woman obsessed with bringing brutal killers to justice. The reclusive, bestselling true-crime writer and investigative consultant has made a life out of chasing monsters. And her powerful intuitions rarely fail her. 
When three adults—loners, drifters—go missing, no one seems to notice except for Lydia. Enlisting the help of her friend, former FBI agent Jeffrey Mark, Lydia starts an investigation of her own. But when someone raises the stakes and goes after Lydia—just as fifteen years ago when she put the FBI on the trail of her mother’s killer—the real hunt begins.

Book Three in Lisa Unger's Lydia Strong series
 
Acclaimed artist Julian Ross has just been found standing over her husband’s bloody corpse in their New York City apartment. Julian claims that she slept peacefully beside him while he was violently stabbed in their bed. But police are skeptical, especially since Julian’s first husband was killed and mutilated in exactly the same way. Julian turns to the tough-as-nails crime writer Lydia Strong, who plunges into the case with her signature grit and the help of her partner, P.I. Jeffrey Mark.       

Meanwhile, Lydia learns that Jed McIntyre, the serial killer who murdered her mother, is on the loose in New York. McIntyre is out for Lydia’s blood, and his presence forces her to confront the evils of her past while solving her toughest murder case yet.
