 A healthy 53-year-old woman is found dead in bed. After performing an autopsy and taking blood and tissue samples, Dr. G cannot find the cause of death. Through conversations with the woman s husband, Dr. G finds out that the woman was suffering from symptoms of a hormonal imbalance and taking over forty dietary supplements a day. Dr. G must find which, if any, of these supplements may have caused her death. After a night of drinking, a 60-year-old man leaves a friend s house on his bicycle and is later found dead in a ditch by the side of the road. It is up to Dr. G to find out whether he fell off his bike or died some other way.
