The Pharaoh's Ghost / The Time Terror

The Pharaoh's Ghost
Originally published with the misspelled title, The Pharoah's Ghost.

In the mysterious land of the sphinx, Doc Savage and his crew confront a sinister foe — who uses a pharaoh’s curse and machine guns to carry out his evil will. Doc trails the malevolent genius to his remote hideout, just as his friends are scheduled for sacrifice to bloodthirsty gods!

The Time Terror
The monstrous winged lizard swooped out of the sky bringing terror and destruction. Was this horrible creature just a freak of nature? Or did it spell the end of humanity? Doc and his aides didn't have time to wonder. They had to push forward-into a lost valley of prehistoric beasts and men!
