Curtis sank down in a chair with his head in his hands and remained motionless for several minutes. At last he looked up.
"I'll answer your questions," he said.
"Why did you never ask Miss Melrose to marry you?"
"Because--well, because I understood another man, Donald MacLean, was in love with her, and she might have loved him. I understood she would have married him had it not been that by doing so she would have caused his disinheritance. MacLean is now in Boston."
"Ah!" exclaimed The Thinking Machine. "Your friend Reid didn't happen to be in love with her, too, did he?"
"Oh, no," was the reply. "Reid came here hoping to win the love of Miss Dow, a society girl. I came with him."
"Miss Dow?" asked Hatch, quickly. "The girl who eloped last night with Morgan Mason?"
"Yes," replied Curtis. "That elopement and this--crime have put Reid almost in as bad a condition as I am."
"What elopement?" asked The Thinking Machine.
Hatch explained how Mason had procured a marriage license, how Miss Dow and Mason had met at the Monarch Inn--where Miss Melrose must have been killed according to all stories--how Miss Dow had written to her parents from there of the elopement and then of their disappearance. The Thinking Machine listened, but without apparent interest.
