worry, whatever happens. I am in possession of
all the facts, so there will be no trouble in proving them. But if
anything disagreeable happens to you," Marjorie Moore gave Bab a
reassuring smile, "telephone me, will you? My number is 1607, Union."

Marjorie Moore rushed out of the street car as hurriedly as she had
entered it, before Bab could take in what she had said.

Barbara puzzled all the rest of the way home. Could it be possible that
Marjorie Moore had discovered Mrs. Wilson's and Peter's plot? Could she
also have guessed Harriet's part in it? Bab shuddered, for she remembered
the newspaper girl's words to her on the night of their first meeting:
"If ever I have a chance to get even with Harriet Hamlin, won't I take my

engagement.

"Try once again, Ruth," Bab pleaded. "It is worse even than you know. I
believe Marjorie Moore suspects what Harriet is about to do. Suppose she
publishes the story in the morning papers. Tell Harriet I have a reason
for thinking she knows about the affair."

Bab waited apprehensively for Ruth's return. It seemed to her that, for
the first time in their adventures, the "Automobile Girls" had met with
a situation that no amount of pluck or effort on their part could
control. This was the most important experience of their whole lives,
for their country was about to be betrayed! Once Barbara stamped her
foot in her impatience. How dared Harriet Hamlin be so willful, so
