Crime-solving means high ratings for Minnesota TV reporter Riley Spartz when she nails the culprit behind Silencing Sam ("Sexy, sinister." -Linda Fairstein). But the stakes rise when Riley must piece together a serial killer's murderous motive for Killing Kate. Channel 3's news director sends Riley on a dog rescue story sure to win over Minneapolis-St. Paul's viewers. But when the Twin City's latest murder victim is someone from Riley's past, she can't stay away. Kate Warner was her college roommate's sister, and the killer's signature-a chalk outline of a winged angel-links him to a string of homicides across the Midwest. Unearthing his agenda leads Riley to the legendary Black Angel statue in an Iowa cemetery-and may lead to a twisted trap designed just for her by the angel killer himself.
