in his uncle's activities.
Most of his time, in fact, was spent out of the apartment. He frequently
went out early in the morning, not returning until the early hours of
the next morning. The old man, on the contrary, always stayed at home
until eleven o'clock. At that hour his telephone would ring. The
telephone was located near the dining room, so Jane could easily hear
his conversations. Invariably some brief message was given to him, a
name, which he repeated aloud as if for verification.

As Jane overheard them she had set them down:

Thursday--"Jones."
Friday--"Simpson."
Saturday--"Marks."
Sunday--"Heilwitz."
Monday--"Lilienthal."
Tuesday--"Wheeler."

As she sat by the hour listening Jane kept pondering over these names.
What could they mean? Were they, too, a code of some sort? Always, as

"Oh, no," said Jane, almost unconsciously rallying to defend him, "he
was born in this country."

"Well, it's a German name."

"Don't you like him?"

"He talks well," her father said, "and seems to be well-bred."

It was with reluctance, too, that Jane admitted to herself that the
better acquainted she became with Frederic Hoff the more fascinating she
found his society. She was always expecting that by some word or action
he would reveal to her his true character. At the matinee she had waited
anxiously to see what he would do when the orchestra played the
national anthem. To her amazement he was on his feet almost among the
first and remained standing in an attitude of the utmost respect until
the last bar was completed. If he were only pr
