Death in the abstract
(Book)

Retired police chief Katherine Sullivan moved away from Edina, Minnesota to feed her artistic soul in New Mexico. But when she receives an urgent call, her serenity is shattered. Nathan Walker, her best friend and former colleague from her days on the police force, is missing and his crew of security experts hasn't seen him in days. Now it's up to Katherine to fly home and track him down. Meanwhile, Edina is reeling from the murder of a local woman, which looks more and more like it could have a connection to Nathan's disappearance. And as Katherine digs deeper into the investigation, locating Nathan's abandoned car and compiling a list of potential kidnappers, another body is found--and Katherine fears time is running out for her friend.
