"It won't look like that a month from now," Constance said, catching his expression. "Just now, you know, the straits and all the northern lakes are locked fast with ice. There's nothing going on now except the winter traffic on Lake Michigan and, to a much smaller extent, on Ontario and Erie; we have an interest in some winter boats, but we don't operate them from here. Next month we will be busy fitting out, and the month after that all the ships we have will be upon the water."
She led the way on past to a door farther down the corridor, which bore merely the name, "Lawrence Sherrill"; evidently Sherrill, who had interests aside from the shipping business, had offices connected with but not actually a part of the offices of Corvet, Sherrill, and Spearman. A girl was on guard on the other side of the door; she recognized Constance Sherrill at once and, saying that Mr. Sherrill had been awaiting Mr. Conrad, she opened an inner door and led Alan into a large, many-windowed room, where Sherrill was sitting alone before a table-desk. He arose, a moment after the door opened, and spoke a word to his daughter, who had followed Alan and the girl to the door, but who had halted there. Constance withdrew, and the girl from the outer office also went away, closing the door behind her. Sherrill pulled the "visitor's chair" rather close to his desk and to his own big leather chair before asking Alan to seat himself.
"You wanted to tell me, or ask me, something last night, my daughter has told me," Sherrill said cordially. "I'm sorry I wasn't home when you came back."
"I wanted to ask you, Mr. Sherrill," Alan said, "about those facts in regard to Mr. Corvet which you mentioned to me yesterday but did not explain. You said it would not aid me to know them; but I found certain things in Mr. Corvet's house last night which made me want to know, if I could, everything you could tell me."
Sherrill opened a drawer and took out a large, plain envelope.
"I did not tell you about these yesterday, Alan," he said, "not only because I had not decided how to act in regard to these matters, but because I had not said anything to Mr. Spearman about them previously, because I expected to get some additional information from you. After seeing you, I was obliged to wait for Spearman to get back to town. The circumstances are such that I felt myself obliged to talk them over first with him; I have done that this morning; so I was going to send for you, if you had not come down."
Sherrill thought a minute, still holding the envelope closed in his hand.
"On the day after your father disappeared," he went on, "but before I knew he was gone—or before any one except my daughter felt any alarm about him—I received a short note from him. I will show it to you later, if you wish; its exact wording, however, is unimportant. It had been mailed very late the night before and apparently at the mail box near his house or at least, by the postmark, somewhere in the neighborhood; and for that reason had not been taken up before the morning collection and did not reach the office until I had been here and gone away again about eleven o'clock. I did not get it, therefore, until after lunch. The note was agitated, almost incoherent. It told me he had sent for you—Alan Conrad, of Blue Rapids, Kansas—but spoke of you as though you were some one I ought to have known about, and commended you to my care. The remainder of it was merely an agitated, almost indecipherable farewell to me. When I opened the envelope, a key had fallen out. The note made no reference to the key, but comparing it with one I had in my pocket, I saw that it appeared to be a key to a safety deposit box in the vaults of a company where we both had boxes.
"The note, taken in connection with my daughter's alarm about him, made it so plain that something serious had happened to Corvet, that my first thought was merely for him. Corvet was not a man with whom one could readily connect the thought of suicide; but, Alan, that was the idea I had. I hurried at once to his house, but the bell was not answered, and I could not get in. His servant, Wassaquam, has very few friends, and the few times he has been away from home of recent years have been when he visited an acquaintance of his—the head porter in a South Side hotel. I went to the telephone in the house next door and called the hotel and found Wassaquam there. I asked Wassaquam about the letter to 'Alan Conrad,' and Wassaquam said Corvet had given it to him to post early in the evening. Several hours later, Corvet had sent him out to wait at the mail box for the mail collector to get the letter back. Wassaquam went out to the mail box, and Corvet came out there too, almost at once. The mail collector, when he came, told them, of course, that he could not return the letter; but Corvet himself had taken the letters and looked them through. Corvet seemed very much excited when he discovered the letter was not there; and when the mail man remembered that he had been late on his previous trip and so must have taken up the letter almost at once after it was mailed, Corvet's excitement increased on learning that it was already probably on the train on its way west. He controlled himself later enough at least to reassure Wassaquam; for an hour or so after, when Corvet sent Wassaquam away from the house, Wassaquam had gone without feeling any anxiety about him.
"I told Wassaquam over the telephone only that something was wrong, and hurried to my own home to get the key, which I had, to the Corvet house; but when I came back and let myself into the house, I found it empty and with no sign of anything having happened.
