Though Embree discovered the right poison, the CIA still needed a delivery method that would allow an operative to literally get away with murder. Dr. Nathan Gordon, a researcher at Fort Detrick, Maryland, discovered that mixing the toxin with water and freezing it would allow a poison dart the width of a human hair and a quarter of an inch long to be fired from a modified M1911.Once in the body, the victim experiences paralytic shellfish poisoning, which can present as a tingling sensation, followed by shortness of breath, abdominal pain, choking and lack of coordination. The victim is paralyzed before dying of respiratory failure in a process that can take seconds. The only evidence of foul play would be a small red puncture wound, one not easily found by a coroner not looking for it. The cause of death would appear to be a heart attack, even to a medical examiner.
