"Thank you," she said. "Lucy told me you had returned, Mr. Royce," she went on, a little tremulously, "and I was anxious to know if you had any news."

"Not yet. Mr. Curtiss was just telling Mr. Lester--"

"Yes," she interrupted, "I saw how he was suffering and I wished to spare him, if I could."

"My dear Mrs. Lawrence," broke in Curtiss, "you must think only of sparing yourself."

"Still," I suggested, "it's possible that Mrs. Lawrence can help us a great deal, if she will."

She was holding herself admirably in hand, and I thought her in much less danger of breaking down than Curtiss himself. Perhaps the old sorrow had taught her how to bear the new one.

"I shall be glad to help you all I can," she said, and smiled a faint encouragement.

It seemed brutal to question her at such a time, but I saw it must be done and I nerved myself to do it.

"Mrs. Lawrence," I began, "has any possible explanation of your daughter's flight occurred to you?"

"No," she answered quickly, and with an emphasis that rather startled me. "It seems to me utterly unexplainable. Even yet, I can scarcely believe it!"

"She left no message for you?"

"Not a word; she simply disappeared."

"And you had no warning?"

"Warning?" she repeated, facing around upon me. "No!"

"Nor suspected that there was anything amiss?"

"Not for an instant."

"Since there was something amiss, why did your daughter not confide in you?"

"I have asked myself the same question. I am utterly unable to answer it."

"She was in the habit of coming to you with her troubles?"

"Always. There was the most perfect confidence between us."

"And yet she concealed this?"

"She did not conceal it!" she protested. "She could not have concealed it from my eyes, even had she wished to. There was nothing to conceal. There was absolutely nothing wrong the last time I saw her."

"And that was?"

"Only a few minutes before she disappeared."

"Will you tell me just what happened?" I suggested, as gently as I could. "Every detail you can remember."

She sat for a moment with compressed lips, steadying herself.

"There's very little to tell," she began. "She was quite her usual self this morning, so far as I could see, and very happy. Two or three of her girl friends came in to see her for a moment, to talk over the final arrangements, and she was giving some directions about the decorations when Mr. Curtiss called. After he had gone, she made a last trip through the house to see that all was right, and then started upstairs to dress. Half an hour later, she came to my room in her wedding-gown to ask how she looked, and I had never seen her looking more beautiful. Only perfect happiness can give such beauty to a woman. I remember thinking what a joy it was to me that she had found a man whom she could love as she loved--"

A half-stifled, choking sob from Curtiss interrupted her. She turned and stretched out her hand to him, with a gesture of infinite affection.

"I finished dressing," she continued, "and then went to Marcia's room, but she wasn't there. Her maid said she'd been called downstairs for a moment. I came down, and found that the decorator had wanted her opinion of the final touches. She had left him, to go upstairs again, as he supposed. It was then nearly half-past eleven, and the bridesmaids began to arrive. I supposed Marcia was in the grounds somewhere, and sent two of the servants to look for her and to tell her it was time to start for the church. They came back saying she was not to be found. Then I began to be alarmed, thinking that she had perhaps been taken suddenly ill, and we searched the house and grounds systematically, but found no trace of her. At last, it seemed just possible that she had gone on to the church, and the bridesmaids hurried into the carriages and drove away-but she wasn't there-only Burr waiting for her--"

She stopped with a sudden tremulousness.

"Thank you," I said. "There's one question I must ask, Mrs. Lawrence, before I can go to work intelligently. You will pardon it. Had your daughter ever had any attachment previous to this one?"

I saw Curtiss glance at her quickly. That solution of the problem had occurred to him, then, too!

"Not the shadow of one," answered Mrs. Lawrence instantly, and perhaps it was only my fancy that the accent of sincerity was a trifle forced. "I have been Marcia's companion and confidante all her life, and I am sure that no man ever distinctly interested her until she met Mr. Curtiss."

"But she no doubt interested many men," I suggested.

"Yes, but never with intention."

"That only makes the case more desperate sometimes."

"I don't believe there were any desperate cases. You will remember," she added, "that we lived much abroad, and so had few intimate acquaintances. Besides, Marcia was-well-extremely patriotic. She often said that she would marry only an American-and an American who lived at home and was proud of his country. One doesn't meet many of that kind in Europe."

"No," I agreed. Whatever my doubts might be, it was clearly impossible at present to proceed any further along that line of inquiry.

And what other line lay open? It seemed to me that I had come to an impa.s.se-a closed way-which barred further progress.

I sat silent a moment, pondering the problem. Perhaps Mrs. Lawrence held the key to it, and I turned to look at her. She was seemingly sunk in reverie, and her lips moved from time to time, as though she were repeating to herself some fragmentary words. She seemed more self-possessed in the presence of this catastrophe than one would have expected. Perhaps she knew where her daughter was; perhaps Miss Lawrence had not really fled. There was nothing to show that she had left the house. It seemed impossible that a woman clad as she had been could have fled, in broad day, without attracting some one's notice. But whether she had fled or not, I reflected, the mystery remained the same. Certainly, she had not appeared at the altar to keep her promise to Burr Curtiss.

"Mrs. Lawrence," I asked, "what reason have you to believe that your daughter left the house?"

She started from her reverie, and sat staring at me as though scarce understanding.

"Why," she said at last, "what else could she have done? She has disappeared--"

"You're sure she isn't concealed somewhere about the place?"

"Concealed?" and she paled a little under my eyes. "Oh, no; that's impossible! We've searched everywhere!"

"And you think she went of her own free will?"

"She could scarcely have been abducted," she retorted. "Marcia is a strong girl, and a single scream would have alarmed the house."

"That's true," I agreed. "Your room is near hers?"

"Just across the hall."

The wish flashed into my brain to look through the house; perhaps I should be able to arrange it.
