ocked and bolted on the
inside.

"Now, I submit to you, Mr. Carter, whether in that case any other way of
entrance or exit was possible except by the windows."

"I'm bound to admit," responded Nick, "that if the doors were in the
condition you describe, no person could have entered or left those rooms
except by the windows."

"Well, it had been raining hard, and the ground was soft. We looked
carefully under all the windows.

"There was no sign of a footprint, and nobody could have walked there
without making tracks. Oh, it is clear enough! Why do we waste your time
in a search for invisible spirits of the dead?"

He rambled on in this way for several minutes, and Nick did not try to
stop him.

The colonel was at last interrupted, however, by the entrance of his
daughter.

Mrs. Pond had been out driving. She learned, on her return, that a
stranger had come to the house, and she hurried into the parlor,
suspecting who was there.

take the case. He didn't believe in it at first, for he did not want to
let anybody into our family secrets."

She glanced at her father as she spoke. It was evident that the family
was a good deal ashamed of Colonel Richmond's spiritualistic delusions
and wanted to keep quiet about them.

"I talked Horace into it after a while," Mrs. Pond continued, "and at
last he became as enthusiastic as myself. We know that you will find the

"Thank you," responded Nick. "There is one point which seems peculiar to
me. After you had been robbed once, why did you continue to leave the
jewels unwatched in the very place from which one of them had previously
been taken?"

"I insisted upon it," said Colonel Richmond. "I told my daughter that
