Memoirs of an Arabian Princess is a classic royal biography by Emilly Ruete. IT WAS at Bet il Mtoni, our oldest palace in the island of Zanzibar, that I first saw the light of day, and I remained there until I reached my seventh year. Bet il Mtoni is charmingly situated on the seashore, at a distance of about five miles from the town of Zanzibar, in a grove of magnificent cocoanut palms, mango trees, and other tropical giants.
