It was about eight o'clock in the evening when Frank knocked at the door of the house in which Mrs. Archer resided, and he was admitted by the mercenary landlady who figured not very creditably upon a former occasion. She immediately recognized the young gentleman, who was dressed in the garments of a laborer; and very civilly informing him that the young lady was at home, requested him to walk upstairs to her room. Our hero assumed a disguise upon that occasion, for this reason: he did not know but that the house was publicly regarded as a brothel; and he therefore did not wish to hazard his reputation by being recognized either while entering or leaving the place. He ascended the stairs and knocked gently at the chamber, which was immediately opened by Mrs. Archer, who pressed his hand with all the warmth of a grateful heart, and placed a chair for him near the fire.--Glancing around the room, Frank saw that she had made every arrangement for her departure: bandboxes and trunks were in readiness for removal, and all her little effects were heaped together in one corner. She herself was dressed with considerable elegance and taste; a close fitting dress of rich silk displayed the fine proportions of her symmetrical form to advantage. 'I know not how to thank you, Mr. Sydney,' she said, seating herself--'for your generous interest in my welfare; but oh! believe me, I am grateful for your kindness.' Frank assured her that he had derived much satisfaction from what services it had been in his power to render, tending to her benefit. He then related to her all that had occurred on the night of the attempted robbery at his house--how her husband had made his escape, and was probably lurking in the Dark Vaults. 'Then he is still at large,' said Mrs. Archer, shuddering--'and I am not yet safe.' 'Fear nothing,' said her benefactor--'he dare not intrude into the respectable and quiet asylum where you are to be placed. No harm can reach you there.' 'God grant it may be so!' fervently ejaculated the young lady; and at that instant some one was heard stealthily ascending the stairs. 'It is Frederick!' she whispered--'you had better conceal yourself, to avoid useless altercation.' Frank quickly secreted himself behind the curtains of the bed, his former hiding place: and in another moment Fred Archer entered the room, and closed the door with extreme caution. 'Maria,' he said, roughly--'I must have money from you to-night; the affair which I spoke to you about, when I was last here, failed most infernally. One of the very fellows who were to assist me in the job, proved to be the owner of the house which we were going to plunder. He had a trap prepared for us, and two of my pals were taken, while I escaped just by a miracle. I dare not go abroad in daylight, for fear of being arrested; and I need money--give it to me!'
