When Mack attends a reunion of prep school friends at a hotel where Holli is coincidentally on a romantic getaway, some of his friends are murdered for which infidelity or business betrayal could be the motive.
A single young, terminally ill mother dies in the emergency room, leaving behind an 8 year old daughter. The mother died because of a lethal dose of poison that produced toxic fumes, causing the medical personnel around her to collapse to the floor. Dr. Holliday suspects foul play. As she seeks to find the poison responsible, she recalls her childhood memories of when her own mother died when she was just 8 years old.
Holli believes that the wife of a policeman who was convicted for the husband's murder before Holli was the medical examiner and who recently escaped from prison acts in a way which suggests the woman might be innocent.
Halli flies to Samoa with Mack to assist in an open case. She falls for a dashing Samoan, who is mixed up in a smuggling ring with a Hong Kong inspector and a female international thief. The object of the ring is to recover the Romanoff jewels and gold, originally stolen during the Russian revolution. An interesting vignette includes the home Robert Louis Stevenson lived in while writing Treasure Island, and Dr. Jekyll and Mr. Hyde.
Mack is selected as part of a security team to protect the Vice President of the United States while on tour of New Zealand. He is also picked by a subversive team of operatives opposed to the V.P's environmental policies to be framed as his assassin. The frame, elaborately, moves from Samoa to New Zealand, and incorporates a number of odd characters and murders. The plot runs similar to the Edmund O'Brien film "D.O.A".
