Empire of the Black Pharaoh

From the publisher's website:

"The end is nigh!

Guarding a starlet on a movie set isn’t really heroic work, but the pay is good and it’s a free vacation. But what begins as a babysitting gig soon turns into something far more sinister, as villains equipped with weird science devices attack the starlet. Is her Egyptian style necklace the reason?

The final installment of the Daring Tales of Adventure line involves two of pulp’s greatest staples—weird science and the ancient world. From the dusty tombs of ancient Egypt to the Acropolis of Athens, the heroes are plagued by dastardly villains with strange powers whose master, the mysterious Black Pharaoh, intends to conquer the world by manipulating the flow of time!"
