Kirby rose and came forward.

"To your knowledge, Mr. Cunningham, had your uncle any enemies?" asked
the attorney, continuing his examination.

"He was a man of positive opinions. Necessarily there were people who
did not like him."

"Active enemies?"

"In a business sense, yes."

"But not in a personal sense?"

"I do not know of any. He may have had them. In going through his
desk at the office I found a letter. Here it is."

The fat little coroner bustled forward, took the letter, and read it.
He handed it to one of the jury. It was read and passed around. The
letter was the one the promoter had received from the Dry Valley
rancher threatening his life if he ever appeared again in that part of
the country.

"I notice that the letter is postmarked Denver," Cunningham suggested.
"Whoever mailed it must have been in the city at the time."

"That's very important," the prosecuting attorney said. "Have you
communicated the information to the police?"
