John Strangways, the British MI6 Station Chief in Jamaica, and his secretary, Mary Trueblood, are ambushed and killed. The assassins steal documents related to "Crab Key" and "Doctor No". In response, M, the head of MI6, instructs agent James Bond to investigate Strangways' disappearance and to determine whether it is related to his co-operation with the American Central Intelligence Agency (CIA) on a case involving the disruption of rocket launches from Cape Canaveral by radio jamming.
