Answer the above question based on the context below:  Holland is a former CIA assassin who lives quietly and peacefully on the Cayman Islands. He is persuaded out of retirement by the death of Jorge Hidalgo, a friend and dissident journalist. Hidalgo was murdered by Clement Molloch, a Welsh doctor who lives in Guatemala. Molloch is an expert in the science of torture and sells his knowledge and skills to any government that can pay his price. He lives under government protection in Guatemala. Holland is hired by Hector Lomelin, a professor and friend of Hidalgo. He poses as a family man and is accompanied to Guatemala by Hidalgo's widow Rhiana and daughter Sarah. Holland kills several of Molloch's men, and then kidnaps his sister Claire, allegedly for ransom. She is killed during a chase by thugs hired by the US ambassador, who has used Molloch for his own purposes in the past. Molloch, believing his sister is still alive, meets Holland at a remote location to pay the ransom. He's kidnapped Hidalgo's daughter Sarah and holds her in exchange for his sister. Local miners know that Molloch has tortured their family members and attack him with pick and shovel. Sarah, her mother Rhiana, and Holland leave his death in the hands of the local people.
