When Mr. Mason came in that night they questioned him eagerly, but he had no real news to tell them. He had been able to prove nothing definite against Jacob Pacomb, and as yet had found no trace of the men who had so frightened Nan.

And Nan, away down in her heart, was still frightened, there could be no doubt of that. The man had threatened her, had given her forty-eight hours to turn over the papers, and more than twenty-four hours of that time had already passed! If they did not succeed in tracing the scoundrels and handing them over to justice in the next twenty-four hours, what might not happen!

Both Rhoda and Grace shared her uneasiness, and lazy Bess grumbled mightily at the loss of sleep consequent upon it. There is no doubt but what the girls would have rested a great deal easier that night had they known that a house detective, well paid for his services, kept watch outside Nan's door till dawn crept in at the windows.

"I wish both of the men were in Greenland," grumbled Bess.

"Yes, and without anything to eat or drink and freezing to death," added Rhoda.

"I can't understand why the authorities can't catch them," put in Grace. "They have a very good description of them."

"Maybe they have left Florida," said Nan.

"Oh, if only they have," cried Bess. "But I am afraid there is no such luck."

It was a weary-eyed quartette of girls that made its way down to the dining-room that morning, and breakfast was eaten in gloomy silence.
