n go back to the station
now, you must be nearly frozen standing here."

Muller looked carefully at the house which bore the number 14. It was a
handsome, old-fashioned building, a true patrician mansion which looked
worthy of all confidence. But Muller knew that the outside of a house
has very little to do with the honesty of the people who live in it.
He rang the bell carefully, as he wished no one but the janitor to hear
him.

The latter did not seem at all surprised to find a stranger asking for
the owner of the house at so late an hour. "You come with a telegram, I
suppose? Come right up stairs then, I have orders to let you in."

These were the words with which the old janitor greeted Muller. The
detective could see from this that Mr. Theodore Fellner's conscience
must be perfectly clear. The expected telegram probably had something
to do with the non-appearance of Asta Langen, of whose terrible fate her
guardian evidently as yet knew nothing. The janitor knocked on one of
the doors, which was opened in a few moments by an old woman.

"Is it the telegram?" she asked sleepily.

"Yes," said the janitor.

The two old people stared at him in surprise.

"To speak to him?" said the woman, and shook her head as if in doubt.
"Is it about Miss Langen?"

"Yes, please wake him."

"But he is ill, and the doctor--"

"But who are you?" asked the janitor.

Muller smiled a little at this belated caution on the part of the
old man, and answered. "I will tell Mr. Fellner who I am. But please
announce me at once. It concerns the young lady." His expression was
so grave that the woman waited no longer, but let him in and then
disappeared through another door. The janitor stood and looked at Muller
with half distrustful, half anxious glances.

"It's no good news you bring," he said after a few minutes.

"You may be right."

"Has anything happened to our dear young lady?"

"Then you know Miss Asta Langen and her family?"

"Why, of course. I was in service on the estate when all the dreadful
things happened."

"What things?"

"Why the divorce--and--but you are a stranger and I shouldn't talk about
these family affairs to you. You had better tell me what has happened to
our young lady."

"I must tell that to your master first."

The woman came back at this moment and said to Muller, "Come with
me,
