Armchair fiction presents large paperback editions of the best in classic science fiction novels. “The Mystery Message” by T. C. Bridges is the 57th installment of our "Lost World-Lost Race Classics" series. It was a mad race through a snake-infested jungle. Jim Selwyn and Sam Lusty were two teenagers who were itching for more adventure in their lives. That opportunity came when a Morse coded message for help came to them from Brazil through Jim’s wireless device. Alan Upton, an explorer and adventurer himself, was reaching out in desperation for help. Upton had discovered a lost city in the wilds of Brazil, populated with the descendants of Atlantis. These Atlantean survivors, called Hulas, guarded over their ancient city of Hulak, which was rich with gold and jewels. But the Hulas were in grave danger from a vicious native tribe called the Bakaïri, who, if successful, planned to conquer the Hulas and throw their entire race into slavery. Upton implored the two lads to contact the esteemed Professor Thorold, his uncle. And before long the Professor and his two teenage companions were off to South America into the steamiest, most dangerous and snake-infested expanse in all Brazil.
