obdurate to anyone else who had been in a position to unbolt the door which offered the only chance of escape from her prison. The house of mystery, she informed me, belonged to a person styling himself Yûssuf of Rosetta (a name that sounded factitious) and she hated him. For two months, I gathered, she had been in Cairo, during which time she had never passed beyond the walls of the neighboring courtyard. And the object of her nocturnal adventure was innocent enough; she wanted to see the European shops and the tourists passing in and out of the big hotels in the Shâria Kâmel Pasha!
