The perfect murder

In trying to unravel the truth behind the murder of his ex-wife and son, Sebastian Costas has followed a ghost of a lead all the way to Sacramento. The evidence suggests a murder-suicide, but something he heard a week before the killing won't allow him to accept that. He believes her second husband - a cop - killed them and then faked his own death. But proving it isn't easy. Then he gets a call from Jane Burke, an investigator with The Last Stand.
