When we had watched her vanish within the walls of the opposite building, Miss Ross—for 'Aunt Ann' was a spinster—deliberately arose and took the place beside me.

'We can talk better so,' she said placidly, 'and I want to talk with thee.' And she began to roll up her knitting with care.

As we sat there I was almost hidden from view from the streets, because of the thick vine tendrils that fell like a curtain between me and the passers-by, while it did not prevent my looking through the green drapery at my pleasure. But Aunt Ann had placed herself where she was plainly visible to all who passed.

'Now,' she began, having put away her knitting, 'I ask thee honestly, sir, does thee think my niece in real danger of any sort? I cannot understand this strangeness.'

'Truly, Miss Ross,' I answered, 'I know no more than you have heard; but I could do no less than warn the young lady, knowing what I did.'

She bent toward me and scrutinized my face closely, keenly.

'Thy face is a good face,' she said then, 'and I like thy voice; but, young man, I am only a woman, and I have no right to do rashly. My niece trusts thee, but she is but a girl, with all her self-reliance. Forgive an old woman's caution, and—tell me what is thy reason for the interest thee takes in my niece? Cannot thee give me some credential, some voucher for thy good faith, before I say to thee what I wish to say?'

Again I found myself forced to a sudden decision. In my experience as a detective I had found myself in many strange situations, but never before had I felt that I must speak the truth, or not at all, in a position like this. I answered, with scarce a moment's hesitation:

'You are right and wise, madam, and I am sure that I can confide to you the truth concerning my business at the Fair—only asking, because others are concerned with myself, that you regard my information as confidential.'

'Surely,' she said quietly. 'Thee may trust a Friend. We are not given to overmuch speaking. Of course thee has my promise.'
