There, settling themselves down to look over the new case on which they were engaged, the first thing that they were confronted with was a want of knowledge as to the antecedents of Norman Ellison, who had so mysteriously disappeared.

“Although Mr. Sanborn,” said Nick, “confided this thing to our hands immediately, it was no time, when he was so agitated and so anxious over the condition of his daughter, to ask him the questions which immediately leaped into my mind. But, what is apparent is, that we cannot even make a place of beginning until we know more about this man, Norman Ellison.”

He got up and paced up and down his room for a while, and finally, stopping at the table, he said:

“His face haunts me. I have seen it somewhere before. Where, I cannot determine. But it is associated with London, and, not only with London, but with the Criterion restaurant, in Piccadilly. But it is all so vague that I can fix nothing.”

“Well,” said Chick, “Ellison is an Englishman and a Londoner. The Criterion is one of the chief restaurants of London, and its bar a great gathering place for the young bloods at night.”

“Yes,” replied Nick, “and I have been there many times. It was there that I caught Commerville, who had run to England after that big forgery of his. But I have seen, perhaps, a thousand faces in that place, first and last, and why should Ellison’s face stick out more prominently than any of the others, if there was nothing wrong in it?”

Further conversation on this head was stopped by the coming of young Mr. Sanborn, the nephew of the millionaire.

He was immediately admitted, and told Nick that his cousin, the young lady who had been married that day, had recovered consciousness, and, though weak, and much agitated, was yet very desirous of seeing him.

Her father had told her that he has committed a search into the hands of the famous detective, and had assured her that nothing that brains, skill, energy and money could accomplish would be left undone to solve the mystery of the disappearance of her newly-made husband. Learning this, the young lady was anxious to have a talk with Nick Carter as soon as she could.

To take the famous detective to her was the reason of young Mr. Sanborn’s call.
