And then as Janice had told him, the taxicab driver had been in the house. He had gone upstairs to the storeroom for Olga's trunk—to the very room in which Janice had last seen the treasure-box.

It might be that the driver was the person guilty of taking the box. Olga might know nothing about it. Yet her disappearance without informing her friends of her intention to leave Greensboro looked suspicious.

Mr. Day had to search further. He had two other persons to discover. One was Olga's "fella"; the other was the Swedish taxicab driver.

From people who knew Olga around the pickle factories it was easy to learn that Olga's friend was a hard working and estimable young man named Willie Sangreen. Just at this time Willie was away from home. They could tell Mr. Day nothing about Willie's absence either at his boarding-house, or where he was employed. But in both instances they were sure Willie would be back.

In hunting for the Swedish taxicab driver Mr. Day had even less good fortune. There were two taxicab companies in Greensboro and less than a dozen independent owners of cabs. Before noon he had learned, beyond peradventure, that there was not a cab driver in town of Swedish nationality.

He presumed that the cab must have come from out of town. Where it had come from, and where it had gone with Olga, and Olga's trunk, and, possibly, with the treasure-box, seemed a mystery insolvable.

If Olga or the cab driver had stolen the box of heirlooms it seemed that all trace of their whereabouts had been skillfully covered.

CHAPTER III. DELIA

In spite of her anxiety Janice fixed her mind upon her recitations with her usual success. During the past few months so many, many things had happened to trouble the home pool that the girl was pretty well used to seeing it ruffled.

"Help" came and went at the Day cottage on Knight Street in a procession of incompetents. Some incumbents of the domestic situation remained but a week. Olga Cedarstrom had been longer than any in Mr. Day's employ.
