intolerable, and the rector within the chancel was not so impatient as alarmed.

A few minutes later the organist stopped altogether. The rector joined the wedding party in the vestibule. Clara had been taken to a room in the vestry by her guardian.

"If he should come now," said Mr. Pembroke, gravely, "I don't believe we could go on. The strain has been too great for Clara."

Dr. Merrill spoke to her as only a clergyman can speak to a parishioner, and minutes dragged along.

At last when an hour had passed, and there was yet no word from Ivan, the rector dismissed the congregation, and the members of the wedding party went homeward, wondering and sorrowful.

CHAPTER II.

AN EXPLANATION SUGGESTED.

"Wait for me a moment, Paul," said Ralph Harmon as the people began to pour out of the church.

He went to the room in the vestry where Clara Hilman sat pale and tearless. With her were Mr. Pembroke, his daughter Louise, and two or three other young ladies who were intimate friends of the unfortunate bride. Ralph did not approach the group, but paused at the door and looked significantly at Miss Pembroke. She went to him at once, and, unseen by the others, he took both her hands in his and said:

"I am going to Strobel's room and shall take Palovna with me. If I find any trace or news, as I undoubtedly shall, I will go directly to your house and report. You may tell Miss Hilman so if you think it will relieve her."

"Clara, dear!" exclaimed Miss Pembroke, impulsively, "Ralph is going to find Ivan, and will come back as quickly as he can to tell you."

For several minutes the bride had been sitting as if petrified, making no answer to the well-meant questions of her friends, unconscious apparently of their tearful sympathy, but at this announcement her eyes were lit by just a gleam of gratitude and she tried to speak to Ralph. Her lips quivered with unformed words, and she turned appealingly to her uncle.

"Come," she faltered, "let us go home."

Ralph bowed and returned immediately to the vestibule, where Paul Palovna waited for him. Both were accosted by many of the outgoing audience, but they shook their heads and hurried down the steps and up the street to the nearest line of cars. They said little to each other on the way to Ashburton Place, for they were oppressed with forebodings, and the consciousness that they had nothing upon which to base speculation.

Once Ralph exclaimed desperately, "What can have happened!" and Paul answered, "He must have fallen violently ill." Both hoped that this might be the case, and neither believed it. Mrs. White knew them both, for they were frequent callers upon her lodger, and her surprise, therefore, passed all bounds when she met them at the door and heard them ask as with one voice, "Where is Strobel?"

"Where?" she repeated, "where should he be? Haven't you seen him?"

"No," replied Ralph, "he did not come to the church, and the rector dismissed the congregation."

Mrs. White threw up her hands and sank into a chair. "Why—why—" she stammered, "he left here all dressed and gay as could be."

"Did he seem quite well?" asked Paul.

The good lady remembered her surprise and disappointment at finding Ivan's eggs unbroken, his breakfast almost untasted and she told the young men about it.

"That signifies nothing," said Paul; "I don't wonder he didn't care to eat. Did he appear to be troubled about anything?"

"Not when he went away," answered Mrs. White; "I thought he seemed put out when the strange gentleman called."

"There we have it!" exclaimed Paul, eagerly. "Who was the caller and what was his business, if you happen to know?"

"I don't know either. I never saw the gentleman before. He was here only a few minutes. He sent up his card, and though I looked at the name, I couldn't remember it, for it had a strange look, something like yours."

"May we go to his room? The card may still be there."

"I don't think it is," said Mrs. White, rising to follow the young men who were already half way up the stairs; "I don't remember seeing it when I cleaned up."

When Ralph and Paul had vainly examined the catch-alls, the vases, and every probable place into which a visitor's card might have been tucked, the Russian asked what had been done with the contents of the waste basket.

"My daughter Lizzie helped me," replied Mrs. White, "and took the waste papers downstairs. I'll ask her to find them and look for the card."

She left the room, and while she was gone the young men moved about nervously, repeatedly asking who the caller could have been, what possible connection his call could have had with Ivan's failure to appear at his wedding, and all manner of questions, vain and irritating, that arise when men are confronted by an emergency that teems with mystery. Mrs. White reported that her daughter had gone out and that the waste paper from Mr. Strobel's room had been burned.

"Lizzie may have seen that card," she said, "and I'll ask her when she comes in. I can't think where she can have gone."

"Was she here when the stranger called?" asked Ralph.

"Oh, yes, and until after Mr. Strobel started away. I didn't know that she had left the house, and I can't imagine what she went out for. Perhaps she'll be back soon."

"Do you know where Strobel hired his carriage?" inquired Paul.

"No, I don't. Lizzie might, for I remember he said something to her about it the day before. I wonder where she——"

"He probably ordered his carriage from Clark & Brown," said Ralph to Paul. He had no intention of ignoring Mrs. White's motherly anxiety about her daughter, but he saw no reason for attaching significance to her absence, and his mind was burdened with a growing conviction that something serious had happened to his friend.

"Suppose we make some inquiries," responded Paul. "If you will go to Clark & Brown's office, I will take a run around all the hotel cab-stands in the vicinity. He might have left his order at the Tremont House or in Bosworth Street, you know."

"I'm agreed," said Ralph. "We must get hold of the man who drove him. One of us is likely to succeed. Suppose, as Strobel may after all turn up at any minute, we meet here as soon as we can. I'll take in the Revere House as well as Clark & Brown's."

"I wish you would meet here, gentlemen," interposed Mrs. White; "Lizzie may be back then."

"I hope she will be, Mrs. White," said Ralph. "She may be able to tell us something about Strobel. It seems strange that he hasn't sent some word."

"I begin to fear that we shall find him at a hospital, badly injured," remarked Paul.

"Oh, I hope not!" exclaimed Mrs. White. "I declare! it makes me feel dreadfully about Lizzie."

The young men departed at once upon their errands. It was Paul Palovna who came upon a clew. He found where Ivan had engaged his carriage, and he went to the livery stable, which was in the South End, to find what had become of the driver and his passenger. He arrived there just after the driver had come in with his damaged carriage.

"I started in with the gentleman," said the driver, "but I broke down at the corner of Tremont and Park Streets and he went along with somebody else."

"Who was it?" asked Paul.

"I don't know. I never saw the cabman before."

"Whose rig was it?"

"I don't know that, either. I never saw the horse before, and the carriage was like hundreds of others that you might see in Boston any day."

Paul tried to think what ought to be done next.

"Did Mr. Strobel have a second accident?" asked one of the stable proprietors.
