“I believe I can prove that I am right, and that he did not,” answered Minnie Renfield, confidently. “Will you allow me?”

“Certainly,” answered Mr. Boise. “This is a serious matter, and I want it cleared up.”

“Then I am going to propose a little experiment,” said the girl with a smile at Tom.

VINDICATION OF TOM

The two lawyers and the telephone boy looked curiously at Miss Renfield.

“I am going out to some telephone,” she said. “I will then call up the office, and each of you, in turn, may speak to me over the wire. I am sure I can tell exactly who is talking, though I am not very familiar with this gentleman’s voice,” and she looked at Mr. Cutler.

“That is the junior member of our firm,” explained Mr. Boise. “I think that will be a fair experiment.”

“I hope it will convince Mr. Cutler that I can recognize voices over the wire,” went on the central operator.

“It ought to be easy to do that,” sneered Mr. Cutler. “You know that only we three are here.”

“You may bring in any other persons you choose,” said Miss Renfield readily, “and, though I may not be able to tell who they are, by name, I will be able to distinguish their voices from yours.”
