Arethusa by F. Marion Crawford

Rustan stayed behind to shut the outer door, and Zoe felt that she was carried as much as twenty paces forward and upwards before the bearers stood still at last. Then the sliding panel opened, letting in light, and a strange voice told her to get out. She turned inside the palanquin and thrust out her naked feet. As she put them down, expecting to touch bare earth or a stone pavement, they rested on a rough carpet; at the same instant she sat on the edge of the litter bending her head to get out of it and looking round curiously.

Rustan was not there, and in his place she saw a huge young negress with flaming red hair and rolling eyes, who roughly ordered the porters to take away the palanquin and at the same time caught Zoe's wrist, whether to help her to stand upright or to secure her person it was hard to say. The girl was much more fearless than Omobono, the Venetian secretary, and she was not frightened by the gigantic woman's appearance, as he had been. In getting out she had managed to gather the cloak round her, so that the men should not see her in her rags; for there was light in the large room where she found herself, and now that she could look about her she saw a dozen or more girls and young women standing in small groups a few paces behind the negress. They surveyed the new arrival curiously, but with different expressions.
