Double Enemies

Professor Joan Vicente offers a unique seminar, where conferees get involved in total lifestyle living far from civilization. What nobody anticipates is terror and deadly deeds. The story opens with a killing, as a professor serving as mentor to an assistant professor loses control. Joan’s mom, Aggie, in her bumbling absentminded way, stumbles across this plot that is now past-tense, but nearly misses the signs that point to the killer.
Meanwhile, in Germany Aggie unwittingly befriends a thug who steals his roommate’s identify. This guy seeks a way to get transportation to America, where he plans to link up with a terrorist cell. He also needs introductions, however, and Agatha, the true-blue American, not only provides him with free passage, she also pleads with Joan to enroll the chap in her mountain retreat, the scene of ultimate mayhem.
