Both Ends of the Night

The extraordinarily popular Sharon McCone, the female private eye who showed Sara Paretsky, Sue Grafton, and company how it's done, takes on a deadly missing persons case. Sharon McCone's flight instructor Matty confides that her boyfriend, John Seabrook, is missing and asks Sharon to find him. Shortly afterwards, Matty is killed in an "accidental" plane crash. More determined than ever, Sharon discovers that, a decade ago, Seabrook was placed in the Federal Witness Protection Program after testifying against a man who has been missing for the last 10 years.
Following sinister leads, Sharon travels to a frozen wilderness -- and comes face-to-face with Matty's killer.
