Here is an entirely new kind of murder mystery -- with a whole nation as the victim. Imagine a sudden mysterious atomic attack on the United States. Imagine one third of the nation destroyed in forty minutes. Imagine being unable to determine the location of the enemy. In a series of thrilling climaxes, Sam Burton and his cohorts in Burrow 89, operating under imminent danger of being blown to bits, manage to discover the murderer, and end the holocaust. Will F. Jenkins (better known in science fiction circles as Murray Leinster) has here turned his pen to the problem of atomic war, has presented the probable defenses, and at the same time has created one of the most dramatic and exciting detective yarns ever written.
