ring down his personal mail from the office to his
private residence.

It was a profitable mail, it was an exciting mail, and it contained an
element of rich promise, for it included a letter from Constable
Wiseman:

DEAR SIR: Re our previous conversation, I have just come across one
of the photographs of the young lady--Sergeant Smith's daughter. It
was given to the private detective who was searching for her. It
was given to my wife by her cousin, and I send it to you hoping it
may be of some use.
Yours respectfully,
PETER JOHN WISEMAN.

The photograph was wrapped in a piece of tissue paper, and Saul Arthur
Mann opened it eagerly. He looked at the oblong card and gasped, for the
girl who was depicted there was the girl he had seen on the steps of 69
Flowerton Road.

A telephone message prepared Frank for the news, and an hour later the
two men were together in the office of the bureau.

"I am going along to that house to see the girl," said Saul Arthur
Mann. "Will you come?"

quarrels I had with my uncle was due to her. She had come up to the
house on behalf of her father, and I thought uncle treated her rather

"Then she disappeared," Frank went on, "and Jasper came on the scene.
There was some association between this girl and Jasper, which I have
never been able to fathom. All I know is that he took a tremendous
interest in her and tried to find her, and, so far as I remember, he
never succeeded."

Mr. Mann's car was at the door, and in a few minutes they were deposited
before the prim exterior of Number 69.

The door was opened by a girl servant, who stared from Saul Arthur Mann
to his companion.

"There is a lady living here," said Mr. Mann.

He produced the photograph.

"This is the lady?"

The girl nodded, still staring at Frank.

"I want to see her."

"She's gone," said the girl.

"You are looking at me very intently," said Frank. "Have you ever seen
me before?"

"Yes, sir," said the girl; "you used to come here, or a gentleman very
much like you. You are Mr. Merrill."

"That is my name," smiled Frank, "but I do not think I have ever been
here before."

"Where has the lady gone?" asked Sa
