Fatal Voyage by Kathy Reichs

Forensic anthropologist Temperance Brennan is returning home when there is a major plane crash involving 88 passengers and crew in the mountains nearby. Given verbal authority to help with assisting with body recovery and identification, she proceeds to do so. Concerned that her daughter might have been one of the passengers, Tempe digs in trying to help solve the cause of the accident. When she discovers a disembodied foot nearby and analysis indicates it could not be from a passenger, Tempe decides to do a little detecting on her own. Coming upon a hidden lodge, forensic evidence indicates there may indeed have been a body on the ground, but it is no longer there. Returning to civilization she seeks help with retrieving evidence and finds doors normally open to her being slammed shut. Makes for a really good mystery and her conclusions certainly make sense. Lots of information about forensics analysis. Sandy Penton
