Episodes

 * Ep 1 The Drum Speaks (4 October 1937) "“Where no white man has set foot” ... So said the explorer, Roger Trelawney, to his daughter Jill, before leaving on his last expedition to Africa—an expedition from which he did not return. Had he ventured there unwillingly, answering to the mysteriously insistent voice of the Sounding Drum, that stained ivory talisman of the Fan-leh-len-do? Edward Gordon and Lord Terry Truscott may have raised doubting eyebrows; that is. until they themselves heard."
 * Ep 2 The First Trick (11 October) "Acting on the precept that surprise is the key-note of attack, Doctor Vaughan strikes with startling suddenness, and in an unexpected quarter. What connection can the color of Lord Truscott’s valet’s hair have with the disappearance of  Roger Trelawney in Central Africa? Apparently none... but  Doctor Vaughan plays the double game—and his first card is  an Ace!"
 * Ep 3 The Flower of Death (15 October) - "The kidnapping of 9am Hackitt shows Doctor Vaughan has yet not all the cards in it. Perhaps the scientific wisdom of Professor Hercules Mosstien will pierce the seemingly impenetrable mystery that surrounds the history of the Sounding Drum.

What it contains brings Jill Trelawney and her friends a little nearer  the truth, but even then it is still just out of reach."

 * Ep 5 Brotherhood of the Ghost Man - "The shrilling of phantom flutes cuts across the brooding African night. . . .

The boma is surrounded with invisible enemies... the party reckoned without  the treachery of Doctor Vaughan."
