Madame Yamilah is a travelling stage performer.
She preforms in act with Ragdalam the Fakir as a clairvoyant and is depicted performing after Bianca Castafiore, where after some novelty predictions, Ragdalam asks her to tell him information about a woman in the audience, Mrs. Clarkson. She correctly states that her husband is a photographer on the Sanders-Hardiman Expedition, and that he has been struck down by the curse of Rascar Capac. She then faints upon telling her the prophecy, falling into Ragdalam's arms. Her act is then followed by General Alcazar. She then appears at Rastapopoulos's act in Alph-Art.
