Half an hour more brought her to the limits of the time which she could venture to allow herself in the open air. In that interval she had searched the sheds from first to last, and had found five more keys. “Five more chances!” she thought to herself, as she hid the keys, and hastily returned to the house.

After first reporting herself in the housekeeper’s room, she went upstairs to remove her bonnet and shawl; taking that opportunity to hide the keys in her bed-chamber until night came. They were crusted thick with rust and dirt; but she dared not attempt to clean them until bed-time secluded her from the prying eyes of the servants in the solitude of her room.

When the dinner hour brought her, as usual, into personal contact with the admiral, she was at once struck by a change in him. For the first time in her experience the old gentleman was silent and depressed. He ate less than usual, and he hardly said five words to her from the beginning of the meal to the end. Some unwelcome subject of reflection had evidently fixed itself on his mind, and remained there persistently, in spite of his efforts to shake it off. At intervals through the evening, she wondered with an ever-growing perplexity what the subject could be.

At last the lagging hours reached their end, and bed-time came. Before she slept that night Magdalen had cleaned the keys from all impurities, and had oiled the wards, to help them smoothly into the locks. The last difficulty that remained was the difficulty of choosing the time when the experiment might be tried with the least risk of interruption and discovery. After carefully considering the question overnight, Magdalen could only resolve to wait and be guided by the events of the next day.

The morning came, and for the first time at St. Crux events justified the trust she had placed in them. The morning came, and the one remaining difficulty that perplexed her was unexpectedly smoothed away by no less a person than the admiral himself! To the surprise of every one in the house, he announced at breakfast that he had arranged to start for London in an hour; that he should pass the night in town; and that he might be expected to return to St. Crux in time for dinner on the next day. He volunteered no further explanations to the housekeeper or to any one else, but it was easy to see that his errand to London was of no ordinary importance in his own estimation. He swallowed his breakfast in a violent hurry, and he was impatiently ready for the carriage before it came to the door.

Experience had taught Magdalen to be cautious. She waited a little, after Admiral Bartram’s departure, before she ventured on trying her experiment with the keys. It was well she did so. Mrs. Drake took advantage of the admiral’s absence to review the condition of the apartments on the first floor. The results of the investigation by no means satisfied her; brooms and dusters were set to work; and the house-maids were in and out of the rooms perpetually, as long as the daylight lasted.

The evening passed, and still the safe opportunity for which Magdalen was on the watch never presented itself. Bed-time came again, and found her placed between the two alternatives of trusting to the doubtful chances of the next morning, or of trying the keys boldly in the dead of night. In former times she would have made her choice without hesitation. She hesitated now; but the wreck of her old courage still sustained her, and she determined to make the venture at night.

They kept early hours at St. Crux. If she waited in her room until half-past eleven, she would wait long enough. At that time she stole out on to the staircase, with the keys in her pocket, and the candle in her hand.

On passing the entrance to the corridor on the bedroom floor, she stopped and listened. No sound of snoring, no shuffling of infirm footsteps was to be heard on the other side of the screen. She looked round it distrustfully. The stone passage was a solitude, and the truckle-bed was empty. Her own eyes had shown her old Mazey on his way to the upper regions, more than an hour since, with a candle in his hand. Had he taken advantage of his master’s absence to enjoy the unaccustomed luxury of sleeping in a room? As the thought occurred to her, a sound from the further end of the corridor just caught her ear. She softly advanced toward it, and heard through the door of the last and remotest of the spare bed-chambers the veteran’s lusty snoring in the room inside. The discovery was startling, in more senses than one. It deepened the impenetrable mystery of the truckle-bed; for it showed plainly that old Mazey had no barbarous preference of his own for passing his nights in the corridor; he occupied that strange and comfortless sleeping-place purely and entirely on his master’s account.

It was no time for dwelling on the reflections which this conclusion might suggest. Magdalen retraced her steps along the passage, and descended to the first floor. Passing the doors nearest to her, she tried the library first. On the staircase and in the corridors she had felt her heart throbbing fast with an unutterable fear; but a sense of security returned to her when she found herself within the four walls of the room, and when she had closed the door on the ghostly quiet outside.
