Elusive Isabel

Elusive Isabel is a novel by Jacques Futrelle first published in 1909. Set in Washington, D.C., it is a spy novel about an international conspiracy of the "Latin" countries against the English-speaking world with the aim to take over world control. Isabel Thorne, is a young woman, half British, half Italian, who works for the Italian secret service and who has been commissioned to bring about the signing of the secret contract right in the capital of the enemy by representatives of all countries involved, both European and American. Her brother, an inventor, has devised a secret weapon by which missiles can be fired from submarines (see also depth charge) which will, it is hoped, secure military dominion over the rest of the world.
