This a.s.surance seemed to satisfy him. His voice and appearance changed; for a moment he looked quite confidential. "Well, well," said he; "and what is it you want to know?"

"I should first like to know how your suspicions came to light on him at all. What reason had you for thinking a gentleman of his bearing and position was in any way connected with this affair?"

"That is a question you ought not to be obliged to put," he returned.

"How so?"

"Simply because the opportunity of answering it was in your hands before ever it came into mine."

"What do you mean?"

"Don't you remember the letter mailed in your presence by Miss Mary Leavenworth during your drive from her home to that of her friend in Thirty-seventh Street?"

"On the afternoon of the inquest?"

"Yes."

"Certainly, but--"

"You never thought to look at its superscription before it was dropped into the box."

"I had neither opportunity nor right to do so."

"Was it not written in your presence?"

"It was."

"And you never regarded the affair as worth your attention?"

"However I may have regarded it, I did not see how I could prevent Miss Leavenworth from dropping a letter into a box if she chose to do so."

"That is because you are a gentleman. Well, it has its disadvantages," he muttered broodingly.

"But you," said I; "how came you to know anything about this letter? Ah, I see," remembering that the carriage in which we were riding at the time had been procured for us by him. "The man on the box was in your pay, and informed, as you call it."

Mr. Gryce winked at his m.u.f.fled toes mysteriously. "That is not the point," he said. "Enough that I heard that a letter, which might reasonably prove to be of some interest to me, had been dropped at such an hour into the box on the corner of a certain street. That, coinciding in the opinion of my informant, I telegraphed to the station connected with that box to take note of the address of a suspicious-looking letter about to pa.s.s through their hands on the way to the General Post Office, and following up the telegram in person, found that a curious epistle addressed in lead pencil and sealed with a stamp, had just arrived, the address of which I was allowed to see--"

"And which was?"

"Henry R. Clavering, Hoffman House, New York."

I drew a deep breath. "And so that is how your attention first came to be directed to this man?"

"Yes."

"Strange. But go on-what next?"

"Why, next I followed up the clue by going to the Hoffman House and inst.i.tuting inquiries. I learned that Mr. Clavering was a regular guest of the hotel. That he had come there, direct from the Liverpool steamer, about three months since, and, registering his name as Henry R. Clavering, Esq., London, had engaged a first-cla.s.s room which he had kept ever since. That, although nothing definite was known concerning him, he had been seen with various highly respectable people, both of his own nation and ours, by all of whom he was treated with respect. And lastly, that while not liberal, he had given many evidences of being a man of means. So much done, I entered the office, and waited for him to come in, in the hope of having an opportunity to observe his manner when the clerk handed him that strange-looking letter from Mary Leavenworth."

"And did you succeed?"

"No; an awkward gawk of a fellow stepped between us just at the critical moment, and shut off my view. But I heard enough that evening from the clerk and servants, of the agitation he had shown on receiving it, to convince me I was upon a trail worth following. I accordingly put on my men, and for two days Mr. Clavering was subjected to the most rigid watch a man ever walked under. But nothing was gained by it; his interest in the murder, if interest at all, was a secret one; and though he walked the streets, studied the papers, and haunted the vicinity of the house in Fifth Avenue, he not only refrained from actually approaching it, but made no attempt to communicate with any of the family. Meanwhile, you crossed my path, and with your determination incited me to renewed effort. Convinced from Mr. Clavering's bearing, and the gossip I had by this time gathered in regard to him, that no one short of a gentleman and a friend could succeed in getting at the clue of his connection with this family, I handed him over to you, and--"

"Found me rather an unmanageable colleague."

Mr. Gryce smiled very much as if a sour plum had been put in his mouth, but made no reply; and a momentary pause ensued.

"Did you think to inquire," I asked at last, "if any one knew where Mr. Clavering had spent the evening of the murder?"

"Yes; but with no good result. It was agreed he went out during the evening; also that he was in his bed in the morning when the servant came in to make his fire; but further than this no one seemed posted."

"So that, in fact, you gleaned nothing that would in any way connect this man with the murder except his marked and agitated interest in it, and the fact that a niece of the murdered man had written a letter to him?"

"That is all."

"Another question; did you hear in what manner and at what time he procured a newspaper that evening?"

"No; I only learned that he was observed, by more than one, to hasten out of the dining-room with the Post in his hand, and go immediately to his room without touching his dinner."

"Humph! that does not look--"

"If Mr. Clavering had had a guilty knowledge of the crime, he would either have ordered dinner before opening the paper, or, having ordered it, he would have eaten it."

"Then you do not believe, from what you have learned, that Mr. Clavering is the guilty party?"

Mr. Gryce shifted uneasily, glanced at the papers protruding from my coat pocket and exclaimed: "I am ready to be convinced by you that he is."

That sentence recalled me to the business in hand. Without appearing to notice his look, I recurred to my questions.

"How came you to know that Mr. Clavering was in this city last summer? Did you learn that, too, at the Hoffman House?"

"No; I ascertained that in quite another way. In short, I have had a communication from London in regard to the matter.

"From London?"

"Yes; I've a friend there in my own line of business, who sometimes a.s.sists me with a bit of information, when requested."

"But how? You have not had time to write to London, and receive an answer since the murder."

"It is not necessary to write. It is enough for me to telegraph him the name of a person, for him to understand that I want to know everything he can gather in a reasonable length of time about that person."

"And you sent the name of Mr. Clavering to him?"

"Yes, in cipher."

"And have received a reply?"

"This morning."
