WHEN EVERYTHING FAILS, TRY THIS a novel by JOHN VESPASIAN. When a Belgian industrialist is diagnosed with cancer and told that he doesn't have long to live, he decides to bet his fortune on Prof. Zirkovsky's research. He convinces Zirkovsky to quit his teaching position in Brussels and set up a laboratory in Charlerois, a small town, in order to conduct experiments with monkeys. When Zirkovsky's research shows the first signs of success, animal-rights activists demand him to abandon his experiments. A series of violent attacks against the lab lead the industrialist to call his insurer, Alfred Grail, a Vietnam veteran living in Switzerland. What Alfred Grail will find in Belgium will shake his beliefs and make him change his life.
