cannot, for two reasons,” he replied. “The first is, because I am not aware of the whole of the circumstances; the second, because I have given her my promise to reveal nothing. Hence my lips are sealed.

I must see her, for I promised her assistance, and am ready to give it in whatever manner she desires.” “You know the conditions,” he said, sauntering carelessly back to me,
