Barnes felt in his pocket and presently produced a letter that had been written him to make inquiry in regard to some matter that he had been attending to for Mr. Field.
Nick Carter scrutinized this closely.
“You know positively that Mr. Field wrote this?”
“I do.”
“Was Mr. Field a methodical man?”
“He was.”
“Where did he usually do his writing?”
“In his library upstairs.”
“At the desk there?”
“Yes.”
