She opened her bag, took out an envelope, removed the letter and passed it across to the interested young man. It was written on the note-heading of Gossip's Corner, but the address had been scratched out by a stroke of the pen. It ran:
"Dear Madam,—
"Certain very important information has come into my possession regarding the relationships between yourself and Captain Brackly. I feel sure you cannot know that your name is being associated with that officer. As the daughter and heiress of the late Sir George Billk, you may imagine that your wealth and position in society relieves you of criticism, but I can assure you that the stories which have been sent to me would, were they placed in the hands of your husband, lead to the most unhappy consequences.
"In order to prevent this matter going any further, and in order to silence the voices of your detractors, our special inquiry department is willing to undertake the suppression of these scandal-mongers. It will cost you £10,000, which should be paid to me in notes. If you agree, put an advertisement in the agony column of the Morning Mist, and I will arrange a meeting where the money can be paid over. On no account address me at my office or endeavour to interview me there.
"Yours very truly,
"J. Brown."
Poltavo read the letter and now the function of Gossip's Corner was very clear. He refolded the letter and handed it back to the girl.
"I may not be very clever," said the visitor, "but I think I can understand what blackmail is when I see it."
Poltavo was in a quandary, but only for a moment.
"I did not write that letter," he said suavely; "it was written without my knowledge. When I said that I was the editor of this paper, I meant, of course, that I was the acting editor. Mr. Brown conducts his business quite independently of myself. I know all the circumstances," he added hastily, since he was very anxious that the girl should not refuse him further information in the belief that he was an inconsiderable quantity, "and I sympathize with you most sincerely."
