The final volume in a trilogy beginning with Umbrella and followed by Shark, Phone tells the story of two men, Zack Busner and Jonathan De’Ath. Busner is a psychiatrist who has made his name through his unorthodox treatment of psychological damage, such as administering LSD to World War II PTSD sufferers.
