Thus attired, he fumbled beneath in his pocket, and then noiselessly ascended the two flights of stairs to an attic door upon which was the circular brass plate of a Yale lock. This he opened, and passing within, closed the door softly behind him. Bernard Boyne naturally believed himself alone in the house with old Mrs. Felmore sound asleep—but, truth to tell, _he was not_! As he ascended the stairs, Marigold’s pale face peered around the corner. The shock of seeing such a hideous ghostly form moving silently upstairs proved almost too much for her. But clinging on to the banisters, she managed to repress the cry of alarm which rose to her lips, and she stood there rooted to the spot—full of wonder and bewilderment. She listened breathlessly, still standing in the dark passage which led to the kitchen stairs. Then she detected the sound of the key going into the lock of the upstairs room where she knew Mr. Boyne kept his private papers. But was it Mr. Boyne? Or was it an intruder who had adopted that garb in order to frighten any person he might encounter? Besides, why should Mr. Boyne assume such a strange disguise before entering the room where his business papers were stored? Now upon that summer night Marigold had called about nine o’clock to visit her aunt, who had in years past been as a mother to her, to have a snack of supper, as she often did. Afterwards she had helped her aunt to prepare Mr. Boyne’s frugal meal. Then old Mrs. Felmore, feeling rather unwell, had gone to bed, leaving her niece in the kitchen to write an urgent letter to Gerald, which she wanted to post before midnight. As she finished the letter, she had heard someone enter, and not desiring that Mr. Boyne should know of her presence there at that hour, she had moved about quietly, and was just about to escape from the house when she had seen that strangely-garbed figure ascending the stairs. The girl’s first impulse had been to waken her aunt and raise an alarm that an intruder had entered the place. But on seeing that the supper had been eaten, and that Mr. Boyne’s hat and coat lay upon the sofa, she at once decided that the figure that had ascended the stairs to the locked room was actually that of the master of the house. "Why is he dressed like that?" she asked herself in a whisper, as she stood in the front parlour. "What can it mean?" She glanced around the room. The cupboard beside the fireplace, which stood open, and from which Boyne had taken his strange disguise, caught her eye. She had never before seen that cupboard open, for her aunt had always told her that Mr. Boyne kept some of his important insurance papers there. Therefore, with curiosity, the girl approached it, finding it practically empty, save for a woman’s big racoon muff, and with it a photograph—that of a handsome, well-preserved woman of about forty, across the front of which had been scrawled in a thin, feminine hand the signature, "Lilla, January, 1919."
