are but a few of the many interesting cases that
have come within the experience of this great detective. But they give a
fair portrayal of Muller's peculiar method of working, his looking on
himself as merely an humble member of the Department, and the
comedy of his acting under "official orders" when the Department is in
reality following out his directions.

THE CASE OF THE REGISTERED LETTER
by Grace Isabel Colbron and Augusta Groner

"Oh, sir, save him if you can--save my poor nephew! I know he is
innocent!"
The little old lady sank back in her chair, gazing up at Commissioner
von Riedau with tear-dimmed eyes full of helpless appeal. The
commissioner looked thoughtful. "But the case is in the hands of the
local authorities, Madam," he answered gently, a strain of pity in his
voice. "I don't exactly see how we could interfere."
"But they believe Albert guilty! They haven't given him a chance!"

"He cannot be sentenced without sufficient proof of his guilt."
"But the trial, the horrible trial--it will kill him--his heart is weak. I
thought--I thought you might send some one--some one of your
detectives--to find out the truth of the case. You must have the best
people here in Vienna. Oh, my poor Albert--"
Her voice died away in a suppressed sob, and she covered her face to
keep back the tears.
The commissioner pressed a bell on his desk. "Is Detective Joseph
Muller anywhere about the building?" he asked of the attendant who
appeared at the door.
"I think he is, sir. I saw him come in not long ago."
"Ask him to come up to this room. Say I would like to speak to him."
The attendant went out.
"I have sent for one of the best men on our force, Madam," continued
the commissioner, turning back to the pathetic little figure in the chair.
"We will go into this matter a little more in detail and see if it is
possible for us to interfere with the work of the local, authorities in
G--."
The little old lady gave her eyes a last hasty dab with a dainty
handkerchief and raised her head again, fighting for self-control. She
was a quaint little figure, with soft grey hair drawn back smoothly from
a gentle-featured face in which each wrinkle seemed the seal of some
loving thought for others. Her bonnet and gown were of excellent
material in delicate soft colours, but cut in the style of an earlier decade.
The capable lines of her thin little hands showed through the fabric of
her grey gloves. Her whole attitude bore the impress of one who had
adventured far beyond the customary routine of her home circle,
adventured out into the world in fear and trembling, impelled by the
stress of a great love.
A knock was heard at the door, and a small, slight man, with a kind,

smooth-shaven face, entered at the commissioner's call. "You sent for
me, sir?" he asked.
"Yes, Muller, there is a matter here in which I need your advice, your
assistance, perhaps. This is Detective Muller, Miss--" (the
commissioner picked up the card on his desk) "Miss Graumann. If you
will tell us now, more in detail, all that you can tell us about this case,
we may be able to help you."
"Oh, if you would," murmured Miss Graumann, with something more
of hope in her voice. The expression of sympathetic interest on the face
of the newcomer had already won her confidence for him. Her slight
figure straightened up in the chair, and the two men sat down opposite
her, prepared to listen to her story.
"I will tell you all I know and understand about this matter, gentlemen,"
she began. "My name is Babette Graumann, and I live with my nephew,
Albert Graumann, engineering expert, in the village of Grunau, which
is not far from the city of G--. My nephew Albert, the dearest, truest--"
sobs threatened to overcome her again, but she mastered them bravely.
"Albert is now in prison, accused of the murder of his friend, John
Siders, in the latter's lodgings in G--."
"Yes, that is the gist of what you have already told me," said the
commissioner. "Muller, Miss Graumann believes her nephew innocent,
contrary to the opinion of the local authorities in G--. She has come to
ask for some one from here who could ferret out the truth of this matter.
You are free now, and if we find that it can be done without offending
the local authorities--"
"Who is the commissioner in charge of the case in G--?" asked Muller.
"Commissioner Lange is his name, I believe," replied Miss Graumann.
"H'm!" Muller and the commissioner exchanged glances.
"I think we can venture to hear more
