Mr. Moore, who was staring out another window at the barely visible glimmer of the Hudson River in the distance, turned to Cyrus and beamed with a little smile of his own. “ ‘Shenandoah,’ ” he murmured quietly, as if to rightly say that Cyrus had found the perfect tune to summarize the strange and melancholy feelings what had only grown stronger in each of us at the sight of the room.

In another shadowy corner, I could see that Miss Howard had made an addition to the furnishings: an enormous Japanese screen, its five panels fully open. Peering out from behind one end of the screen was a section of a large black standing chalkboard, bordered in oak: the board, as we’d always known it. How long had it been hidden away? I wondered.

Miss Howard, having given us a few minutes to adjust to our return, now rubbed her hands in anticipation and again spoke with a kind of hesitation what was unusual for her.

“Señora Linares is in the kitchen, having tea. I’ll just get her.”

She glided back toward the rear of the building, where a dimly lit doorway indicated some sign of life. Again automatically, I walked over and jumped onto one of the windowsills that overlooked the church garden-my accustomed roost in this place-and took a small knife out of my pocket, using its blade to trim my fingernails as Cyrus continued to play and we heard the seemingly faraway sound of the two women’s voices in the kitchen.

Soon a pair of silhouettes appeared against the faint light in the kitchen doorway, and even in the near darkness I could see that Miss Howard was helping the other lady walk-not so much because the woman was physically unable to stand on her own (though she did seem in some pain) but more to help her overcome what I sensed was a kind of terrible dread. As they came into the center of the room, I could see that the woman had a fine figure and was richly dressed in black: layer upon layer of satin and silk, all of it crowned by a broad hat from which drooped a heavy black veil. She held an ivory-handled umbrella in one hand, and as Sara let go of her arm she steadied herself on it.
