"Oh, yes," chorused the willing victims.

"It is well," chanted the third figure.

"It is well," echoed the fourth.

"I don't," said Libbie calmly.

"Don't what?" questioned the tallest figure, evidently appointed chief
spokesman.

"Want to be a member of the Mysterious Four," announced Libbie, who had
an obstinate streak in her make-up.

"Unfortunately," the spokesman informed her, "you haven't any choice in
the matter; you're elected one already."

While Libbie was thinking up an answer, which considering the finality
of that statement, was not an easy matter, the tall draped figure went
on to explain to the interested girls that there were two degrees to
be undergone before one could be a full fledged member of the
Mysterious Four.

"You must take the first degree to-night," they were told. "The second
will be several weeks later."

"Are we allowed to ask a question?" asked Betty respectfully.

"Oh, yes. But we may not answer it," was the cheering response.
