ensued which not only disunited their lives but sent them to opposite sides of the globe never to return again. At least, that was the inference drawn from the peculiar circumstances attending the event. On the morning of one never-to-be-forgotten day, John Van Broecklyn, the grandfather of the present representative of the family, found the following note from his son lying on the library table:
"Father:
"Life in this house, or any house, with her is no longer endurable. One of us must go. The mother should not be separated from her child. Therefore it is I whom you will never see again. Forget me, but be considerate of her and the boy.
"William."
Six hours later another note was found, this time; from the wife:
"Father:
"Tied to a rotting corpse what does one do? Lop off one's arm if necessary to rid one of the contact. As all love between your son and myself is dead, I can no longer live within the sound of his voice. As this is his home, he is the one to remain in it. May our child reap the benefit of his mother's loss and his father's affection.
"Rhoda."
Both were gone, and gone forever. Simultaneous in their departure, they preserved each his own silence and sent no word back. If the one went East and the other West, they may have met on the other side of the globe, but never again in the home which sheltered their boy. For him and for his grandfather they had sunk from sight in the great sea of humanity, leaving them stranded on an isolated and mournful shore. The grandfather steeled himself to the double loss, for the child's sake; but the boy of eleven succumbed. Few of the world's great sufferers, of whatever age or condition, have mourned as this child mourned, or shown the effects of his grief so deeply or so long. Not till he had passed his majority did the line, carved in one day in his baby forehead, lose any of its intensity; and there are those who declare that even later than that, the midnight stillness of the house was disturbed from time to time by his muffled shriek of "Mother! Mother!" sending the servants from the house, and adding one more horror to the many which clung about this accursed mansion.
Of this cry Violet had heard, and it was that and the door—But I have already told you about the door which she was still looking for, when her two companions suddenly halted, and she found herself on the threshold of the library, in full view of Mr. Van Broecklyn and his two guests.
Slight and fairy-like in figure, with an air of modest reserve more in keeping with her youth and dainty dimpling beauty than with her errand, her appearance produced an astonishment which none of the gentlemen were able to disguise. This the clever detective, with a genius for social problems and odd elusive cases! This darling of the ball-room in satin and pearls! Mr. Spielhagen glanced at Mr. Carroll, and Mr. Carroll at Mr. Spielhagen, and both at Mr. Upjohn, in very evident distrust. As for Violet, she had eyes only for Mr. Van Broecklyn who stood before her in a surprise equal to that of the others but with more restraint in its expression.
She was not disappointed in him. She had expected to see a man, reserved almost to the point of austerity. And she found his first look even more awe-compelling than her imagination had pictured; so much so indeed, that her resolution faltered, and she took a quick step backward; which seeing, he smiled and her heart and hopes grew warm again. That he could smile, and smile with absolute sweetness, was her great comfort when later—But I am introducing you too hurriedly to the catastrophe. There is much to be told first.
I pass over the preliminaries, and come at once to the moment when Violet, having listened to a repetition of the full facts, stood with downcast eyes before these gentlemen, complaining in some alarm to herself:
"They expect me to tell them now and without further search or parley just where this missing page is. I shall have to balk that expectation without losing their confidence. But how?"
Summoning up her courage and meeting each inquiring eye with a look which seemed to carry a different message to each, she remarked very quietly:
"This is not a matter to guess at. I must have time and I must look a little deeper into the facts just given me. I presume that the table I see over there is the one upon which Mr. Upjohn laid the manuscript during Mr. Spielhagen's unconsciousness."
All nodded.
"Is it—I mean the table—in the same condition it was then? Has nothing been taken from it except the manuscript?"
"Nothing."
"Then the missing page is not there," she smiled, pointing to its bare top. A pause, during which she stood with her gaze fixed on the floor before her. She was thinking and thinking hard.
Suddenly she came to a decision. Addressing Mr. Upjohn she asked if he were quite sure that in taking the manuscript from Mr. Spielhagen's hand he had neither disarranged nor dropped one of its pages.
The answer was unequivocal.
"Then," she declared, with quiet assurance and a steady meeting with her own of every eye, "as the thirteenth page was not found among the others when they were taken from this table, nor on the persons of either Mr. Carroll or Mr. Spielhagen, it is still in that inner room."
"Impossible!" came from every lip, each in a different tone. "That room is absolutely empty."
"May I have a look at its emptiness?" she asked, with a naïve 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.
With difficulty Violet preserved her show of composure. "The door!" she murmured to herself. "I have found it. The great historic door!" But her tone was light as she ventured to say:
"Then it can no longer be opened by your hand or any other?"
"It could not be opened with an axe."
Violet sighed in the midst of her triumph. Her curiosity had been satisfied, but the problem she had been set to solve looked inexplicable. But she was not one to yield easily to discouragement. Marking the disappointment
