In one corner of the library stood a tall, brass-mounted chiffonier filled with papers, and above it hung an engraving. Behind, and entirely concealed, was a door opening into a small bathroom that formed an alcove in the senator's apartment. After an hour had passed, Mrs. Mitchell placed her shoulder against the chiffonier, that rolled easily on its castors, and she slipped behind it. There was no key in the lock, but a slender steel bolt slid horizontally under her hand, and the door opened a few inches only, barred by a table, which she succeeded in pushing aside. Lifting the portiere inside, she entered the sleeping-room, and found the _robe de chambre_ hanging over the back of a chair. The pockets were empty, the drawers of the bureau locked, but under the pillow on the bed she thrust one hand and drew out the object of her search. It contained neither date nor signature, and was type-written in purple ink on thin paper bearing no water-mark. "A friend to you and to yours believes it a genuine kindness to inform you that the identity of 'Ely Twiggs' has been discovered, and hopes an early knowledge of this fact may be useful to you." She replaced the note beneath the pillow, returned to the library, and rolled back the chiffonier. After all, she had ended her quest in a cul-de-sac. Turning the gas jets low, she sat watching the blue flicker that danced like witch-lights in the grate, and once she smiled at her own discomfiture, realizing that her attempt was futile as would be the trial of a Yale key to open a "combination" vault lock, the arrangement of which was unknown. Keenly alert, she heard the rattle of the night-latch, the closing of the front door, and, after a moment, Judge Kent came slowly into the room. At first he did not notice her presence, and in this brief unguarded interval she saw the countenance without its habitual mask--a face gloomy, perturbed, unnaturally flushed, with restless eyes gleaming like those of a jaded, hunted forest animal. "Ah--Mrs. Mitchell! Sitting up for Eglah? Didn't she tell you she was going from the dinner to the cotillon? Herriott will see her home. It is a shame to have kept you up, but girls are so thoughtless." "Eglah is never that, and I knew she would be late at the cotillon. I waited downstairs solely to see you." "Very kind, I am sure; but I feel much better, thank you. Indeed, I may say I have fully recovered from that sudden, intolerable spell of nausea. You are very good to worry over that little attack, but pray think no more about it. I shall abjure Welsh rarebit and oysters in future. At my time of life, pneumogastric nerves get their innings." Brightening the light in the gas globe over the mantel, she approached and confronted him.
