"I happened to be the one to go to Spanish Falls for the mail that day. The postmark excited my curiosity. If I told you what I did to that letter before delivering it to Mr. Loeb, you could send me to a federal prison. But that's how I came to know that she had decided to wait in Crowndale until he sent word that the coast was clear. She went to the big sanatorium outside the town and has been there ever since, incognito, taking a cure for something or other. She goes by the name of Mrs. Hasselwein. I popped down here this afternoon and found out that she is still at the sanatorium but expects to leave early to-morrow morning. Her trunks are over at the station now, to be expressed to Buffalo. I made another trip out there this evening and waited. About eight o'clock Mr. Hasselwein strolled up. He sat on the verandah with her for half an hour or so and then left. I followed him. He went to one of the little cottages that belong to the sanatorium. I couldn't get close enough to hear what they said, but I believe he expects to take her away in an automobile early in the morning. It is a seventy mile ride from here to the junction where they catch the train for the west. I'm going up now to make a call on Mr. Hasselwein. Would you like to join me?"
Barnes eyed him narrowly. "There is only one reason why I feel that I ought to accompany you," he said. "If you have it in your mind to kill him, I certainly shall do everything in my power to prevent--"
"Possess your soul in peace. I'm not going to do anything foolish. Time enough left for that sort of thing. I will get him some day, but not now. By the way, what is the number of your room?"
"Twenty-two,--on the next floor."
"Good. Go upstairs now and I'll join you in about ten minutes. I will tap three times on your door."
"Why should you come to my room, Sprouse? We can say all that is to be said--"
"If you will look on the register you will discover that Mr. J. H. Prosser registered here about half an hour ago. He is in room 30. He left a call for five o'clock. Well, Prosser is another name for Ugo."
"Here in this hotel? In room 30?" cried Barnes, incredulously.
"Sure as you're alive. Left the cottage an hour ago. Came in a jitney or I could have got to him on the way over."
