This self-appointed guide was no negro, no mulatto, of that Manuel was sure. The money had been received without that wide answering grin of pleasure characteristic in almost all negro types. Moreover, the palms of the boy's hands were the same color as the rest of his skin. The Cuban knew well that a certain dirty pallor is always evident on the palms of the hands of even the blackest negroes.

The boy's reference to the "Citadel of the Black Emperor" showed that he was aware of this secret meeting of conspirators.

This was grave.

More, he was disguised.

This was graver still.

Was this boy, too, afraid of Haiti, that savage land at the doors of America; that abode where magic, superstition and even cannibalism still lurk in the forests; that barbarous republic where the white man is despised and hated, and the black man dominates? That land where the only civilizing force for a century has been a handful of American marines!

That this boy was disguised suggested that he was in fear for his life; but, if so, why was he there? How did he come to know the pass-word of the conspiracy? For what mysterious reason did he offer himself as a guide to the haunted place of meeting?

Who was this boy?

Manuel turned into the Café de l'Opéra, a tumble-down frame shack with a corrugated iron roof, to order a cooling drink and to puzzle out this utterly baffling mystery.

The Cuban's first impulse was to flee. Had anything less imperious than this all-important meeting been before him, Manuel would have made his escape without a moment's delay.
