THE RADIO DETECTIVES IN THE JUNGLE

?To those who have followed the Radio Detectives through their previous adventures the group upon the crippled destroyer?s decks will need no introduction. There was the trim, spick-and-span Commander Disbrow, the deep-sea diver, Rawlins, Mr. Pauling and his friend Mr. Henderson and the two boys, Tom Pauling and his chum Frank. But for the benefit of those who now meet the Radio Detectives for the first time a few words of explanation will be needed. Months before the story opens, Tom Pauling and Frank had discovered a most astounding plot by means of their radio telephones and thereby enabled Tom?s father and his associate, Mr. Henderson, who were federal officers in the Secret Service, to make prisoners of a number of members of an international gang of scoundrels whose activities included the distribution of Bolshevist literature, the destruction of property, smuggling contraband liquor into the United States and conducting a widespread series of holdups, robberies and other crimes."
