The Fantastic Adventures of Doc Savage.

Doc Savage investigates a strange fainting sickness and a shadowy white-haired man named McCain.

Into a subterranean world of red-hot lava, Doc Savage and his fantastic five descend -- to face the most fiendish foe of his career. Awaiting Doc is an irresistible power that can level mountains... that can enslave the world... and that threatens to make Doc's most dangerous adventure his very last...

To the world at large, Doc Save is a strange, mysterious figure of glistening bronze skin and golden eyes. To his amazing co adventurers the five greatest brains ever assembled in one group – he is a man of superhuman strength and protean genius, whose life is dedicated to the destruction of evil doers. To his fans he is the greatest adventure hero of all time, whose fantastic exploits are unequalled for hair raising thrills, breathtaking escapes and bloodcurdling excitement. The deep mysteries of Doc Savage are finally revealed! John Sunlight, poetic genius of evil, gruesome master of a thousand elements of creaming terror, discovers the innermost secrets of The Man of Bronze. Doc Savage finds himself enmeshed in a diabolical web of dark horror as he valiantly battles the appealing machines of destruction he himself has invented.

Doc Savage is jailed, but all the prison bars in the world could not hold him when he was on his way to dispelling the madness in the desert that changes people into other identities.

One by one the rich nitrate miners of Antofagasta, Chile, were being hideously crushed to death by falling boulders. Then the Man of Bronze saw the evil hand of The Mad Earth Shaker -- and uncovered his terrifying plot to control the world!

There was only one clue to the bloody enigma of TAZ--the illegible, dying scrawl of a horribly mutilated sailor. Held captive aboard a tramp steamer, the Man of Bronze and his allies wrestle with the dread riddle of TAZ and the mystery of Captain Flamingo.

A ruthless attempt on the life of one of Doc’s crew thrusts the Man of Bronze and his incomparable companions into a chilling new adventure. From the ancient, skull-lined catacombs of Alexandria to a fantastic sea of floating primitive life where they unravel the centuries-old mystery of the Sargasso, Doc Savage and his men once more pursue the perverse agents of evil!

Men by the name of Smith are being killed all over town. They are killed by lightning that enters the room without leaving any marks, on a day when there was no lightning.
