The Trollenberg Terrors storyline concerns United Nations troubleshooter Alan Brooks, later joined by journalist Philip Truscott, investigating unusual accidents occurring in the area of a resort hotel on the fictional Mount Trollenberg in Switzerland. Brooks suspects that these deaths are related to a series of similar incidents which occurred three years earlier in the Andes Mountains, which involved an unexplained radioactive mist and an odd cloud formation believed by locals to be inhabited. Plot On the Swiss mountain Trollenberg, one of three student climbers is suddenly killed, his head ripped from his body. Two sisters, Anne and Sarah Pilgrim, a London mind-reading act, are travelling by train to Geneva when Anne faints as the train passes the mountain. Upon waking, Anne insists that they must get off at the next stop. UN troubleshooter Alan Brooks, in the same train compartment as the sisters, is going to Trollenberg's observatory to meet with Professor Crevett. Crevett goes on to explain that, despite many climbing accidents, no bodies are ever found, and an always-stationary radioactive cloud is regularly observed on the mountain's south face. Brooks mentions similar incidents that took place in the Andes three years earlier, just before a similar radioactive cloud vanished without a trace. Local rumors circulated that something was living in the heavy mist. Anne is giving a mind-reading demonstration at the nearby hotel when she "sees" two men in a base camp hut on the mountain. Dewhurst is asleep when the other man, Brett, under some kind of mental compulsion, walks outside as the cloud
