er letters to be sent to that city proved nothing. It did not
make it certain that she lived in the town.

"We are only at the beginning of our perplexities, Philip," said Mr.
Carter. "Your friends may be near us, or they may be a hundred miles
away."

"That is true, sir."

"One method of finding them is barred, that of advertising, since they
undoubtedly do not care to be found, and an advertisement would only
place them on their guard."

"What would you advise, sir?"

"We might employ a detective to watch the post-office, but here again
there might be disappointment. Mrs. Brent might employ a third person
to call for her letters. However, I have faith to believe that sooner or
later we shall find her. Time and patience accomplishes much."

"Were you ever a detective, sir?" asked Phil, smiling.

"No, Philip, but I have had occasion to employ them. Now how would you
like to go to the theater this evening?"

"Very much, sir."

"There is a good play running at McVicker's Theatre. We will go there."

"Anywhere will suit me, Mr. Carter."

"Young people are easily satisfied," he said. "When they get older they
get more fastidious. However, there is generally something attractive at
McVicker's."

It so happened that Philip and his employer took a late dinner, and did
not reach the theater till ten minutes after the hour. They had seats
in the seventh row of orchestra chairs, a very eligible portion of the
house.

The curtain had risen, and Philip's attention was given to the stage
till the end of the first act. Then he began to look around him.

Suddenly he started and half rose from his seat.

"What is the matter, Philip?" asked Mr. Carter.

"There, sir! look there!" said the boy, in excitement, pointing to two
persons in the fourth row in front.

"Do you recognize acquaintances, Philip?"

"It is my step-mother and Jonas," answered Philip eagerly.

"It is, indeed, wonderful!" said Mr. Carter, sharing the boy's
excitement. "You are confident, are you?"

"Oh, sir, I couldn't be mistaken about that."

Just then Mrs. Brent turned to a gentleman at her side and spoke. It was
Mr. Granville.

"Who is that gentleman?" said Mr. Carter reflectively. "Do you think
Mrs. Brent is married again?"

"I don't know what to think!" said Philip, bewildered.

"I will tell you what to do. You cannot allow these people to elude you.
