He rose.
"That finishes our interview. You will come here to-morrow morning and let yourself in. Here is the key of the door and a key to the safe in which I keep all correspondence. You will find much to incriminate society and precious little that will incriminate me. I expect you to devote the whole of your attention to this business," he said slowly and emphatically.
"You may be sure – " began Poltavo.
"Wait, I have not finished. By devoting the whole of your attention to the business, I mean I want you to have no spare time to conduct any investigations as to my identity. By a method which I will not trouble to explain to you I am able to leave this building without any person being aware of the fact that I am the editor of this interesting publication. When you have been through your letters I want you to translate those which contain the most important particulars and forward them by a messenger who will call every evening at five o'clock. Your salary will be paid regularly, and you will not be bothered with any editorial duties. And now, if you will please go into the outer room and wait a few moments, you may return in five minutes and begin on this accumulation of correspondence."
Poltavo, with a little bow, obeyed, and closed the door carefully behind him. He heard a click, and knew that the same electric control which had opened the outer door had now closed the inner. At the end of five minutes, as near as he could judge, he tried the door. It opened readily and he stepped into the inner office. The room was empty. There was a door leading out to the corridor, but something told the new assistant that this was not the manner of egress which his employer had adopted. He looked round carefully. There was no other door, but behind the chair where the veiled man had sat was a large cupboard. This he opened without, however, discovering any solution to the mystery of Mr. Brown's disappearance, for the cupboard was filled with books and stationery. He then began a systematic search of the apartment. He tried all the drawers of the desk and found they were open, whereupon his interest in their contents evaporated, since he knew a gentleman of Mr. Brown's wide experience was hardly likely to leave important particulars concerning himself in an unlocked desk. Poltavo shrugged his shoulders, deftly rolling a cigarette, which he lit, then pulling the chair up to the desk he began to attack the pile of letters which awaited his attention.
For six weeks Mr. Poltavo had worked with painstaking thoroughness in the new service. Every Friday morning he had found on his desk an envelope containing two bank notes neatly folded and addressed to himself. Every evening at five o'clock a hard-faced messenger had called and received a bulky envelope containing Poltavo's translations.
The Pole was a keen student of the little paper, which he bought every week, and he had noted that very little of the information he had gleaned appeared in print. Obviously then Gossip's Corner served Mr. Brown in some other way than as a vehicle for scandal, and the veil was partly lifted on this mysterious business on an afternoon when there had come a sharp tap at the outer door of the office. Poltavo pressed the button on the desk, which released the lock, and presently the tap was repeated on the inside door.
The door opened and a girl stood in the entrance hesitating.
"Won't you come in?" said Poltavo, rising.
"Are you the editor of this paper?" asked the girl, as she slowly closed the door behind her.
Poltavo bowed. He was always ready to accept whatever honour chance bestowed upon him. Had she asked him if he were Mr. Brown, he would also have bowed.
"I had a letter from you," said the girl, coming to the other side of the table and resting her hand on its edge and looking down at him a little scornfully, and a little fearfully, as Poltavo thought.
He bowed again. He had not written letters to anybody save to his employer, but his conscience was an elastic one.
"I write so many letters," he said airily, "that I really forget whether I have written to you or not. May I see the letter?"
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.
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."
A little smile curled the lips of the visitor.
Poltavo was ever a judge of men and women, and he knew that this was no yielding, timid creature to be terrified by the fear of exposure.
"The matter can be left in the hands of Captain Brackly and my husband to settle," she said. "I am going to take the letter to my solicitors. I shall also show it to the two men most affected."
Now the letter had been written four days earlier, as Poltavo had seen, and he argued that if it had not been revealed to these "two men most affected" in the first heat of the lady's anger and indignation, it would never be shown at all.
"I think you are very wise," he said suavely. "After all, what is a little unpleasantness of that character? Who cares about the publication of a few letters?"
"Has he got letters?" asked the girl quickly, with a change of tone.
Poltavo bowed again.
"Will they be returned?" she asked.
Poltavo nodded, and the girl bit her lips thoughtfully.
"I see," she said.
She looked at the letter again and without another word went out.
Poltavo accompanied her to the outer door.
"It is the prettiest kind of blackmail," she said at parting, and she spoke without heat. "I have only now to consider which will pay me best."
The Pole closed the door behind her and walked back to his inner office, opened the door and stood aghast, for sitting in the chair which he had so recently vacated was the veiled man.
He was chuckling, partly at Poltavo's surprise, partly at some amusing thought.
"Well done, Poltavo," he said; "excellently fenced."
"Did you hear?" asked the Pole, surprised in spite of himself.
"Every word," said the other. "Well, what do you think of it?"
Poltavo pulled a chair from the wall and sat down facing his chief.
"I think it is very clever," he said admiringly, "but I also think I am not getting sufficient salary."
