"What has dampened your hopes?"
"You are too cool for a man who has found the letter."
"I am?"
"Yes."
There came a smile to the detective's face, a smile that was thrilling in its suggestiveness, as he laid the letter on the table and said:
"Well, I have found something; you can tell what it is; look at it. No need to search now; I think the search is over."
Mr. Townsend advanced, seized the letter, and his face was ashen as he exclaimed, while trembling like one with ague:
"That is it."
"I thought so," said the detective.
"Yes, that is the letter."
