“Absolutely positive. You know the number of the telephone in the Attorney General’s private office at his home is not listed in the regular book, as is his house wire. His private telephone is ‘North—123’; I remember it because it is so easy; and the other is ‘North—6795.’”

“But as to the time, Nancy?”

“I am certain about that, too. It was very quiet in the Exchange, and when the call came I nearly jumped out of my skin. I looked at the big wall clock directly opposite, and I saw it was fifteen minutes past two.”

“Nancy, you are a wonder—a brick. But why didn’t you come forward and give your evidence at the inquest?”

“Oh, I couldn’t, Dick,” the young girl colored painfully. “I went to work at the Exchange because we are so frightfully poor; but I—I—just couldn’t face the notoriety which I feared I would be dragged into. Then again, it might not have anything to do with the terrible affair.”

“Do?” echoed Dick; his tone was eloquent. “Was the telephone answered?”

“Yes, at once.”

“Now, do you happen to know where the call came from?”

“Yes. It was—‘Main 6.’”

Dick gazed at her too spellbound for words.
