“May I have a look at its emptiness?” she asked, with a naive glance at Mr. Van Broecklyn.

“There is positively nothing in the room but the chair Mr. Spielhagen sat on,” objected that gentleman with a noticeable air of reluctance.

“Still, may I not have a look at it?” she persisted, with that disarming smile she kept for great occasions.

Mr. Van Broecklyn bowed. He could not refuse a request so urged, but his step was slow and his manner next to ungracious as he led the way to the door of the adjoining room and threw it open.

Just what she had been told to expect! Bare walls and floors and an empty chair! Yet she did not instantly withdraw, but stood silently contemplating the panelled wainscoting surrounding her, as though she suspected it of containing some secret hiding-place not apparent to the eye.

Mr. Van Broecklyn, noting this, hastened to say:

“The walls are sound, Miss Strange. They contain no hidden cupboards.”

“And that door?” she asked, pointing to a portion of the wainscoting so exactly like the rest that only the most experienced eye could detect the line of deeper colour which marked an opening.

For an instant Mr. Van Broecklyn stood rigid, then the immovable pallor, which was one of his chief characteristics, gave way to a deep flush as he explained:

“There was a door there once; but it has been permanently closed. With cement,” he forced himself to add, his countenance losing its evanescent colour till it shone ghastly again in the strong light.
