I have been in Istanbul, partly to research a French-born collateral ancestor of mine, Aimée Dubucq, who, according to legend, was captured by Corsairs in 1778 and presented to the Sultan of Turkey as a gift. Known in captivity as Naksh, or ‘The Beautiful One’, she was 19 when she was taken by boat to Seraglio Point, where stands the Topkapi Palace, the most exquisite and imposing royal residence in the world. The chief black eunuch, Son Altesse Noir, inspected every new arrival to the Harem, and he would have escorted Aimée through its kiosks, pavilions and gardens of splashing fountains, past the sound of parakeets squawking and, less happily, the cries of miscreants in the dungeons. Not even Turkish scholars know what really happened in the Harem.
