y summoned a taxicab for her.

Kennedy improved the opportunity by calling another for us and by the
time she was ready to drive off we were able to follow her. She drove to
the Prince Henry Hotel, where she dismissed the machine and entered. We
did the same.

"By the way," asked Kennedy casually, sauntering up to the desk after
she had stopped to get her keys and a letter, "can you tell me who that
woman was?"

The clerk ran his finger down the names on the register. At last he
paused and turned the book around to us. His finger indicated: "Mrs.
Katherine Du Mond, Chicago."

Kennedy and I looked at each other in amazement. Du Mond was married and
his wife was in town. She had not made a scene. She had merely watched.
What could have been more evident than that she was seeking evidence and
such evidence could only have been for a court of law in a divorce suit?
The possibilities which the situation opened up for Gloria seemed
frightful.

We left the hotel and Kennedy hurried down Broadway, turning off at the
office of a young detective, Chase, whom he used often on matters of
pure routine for which he had no time.

"Chase," he instructed, when we were seated in the office, "you recall
that advertisement of the lost necklace in the _Star_ by La Rue & Co.?"

The young man nodded. Everyone knew it. "Well," resumed Kennedy, "I want
you to search the pawnshops, particularly those of the Tenderloin, for
any trace you can find of it. Let me know, if it is only a rumor."

There was nothing more that we could do that night, though Kennedy found
out over the telephone, by a ruse, that, as he suspected, the country
place of the Cabaret Rouge was the objective of the gay party which we
had seen.

CHAPTER III

THE FOX HUNT

The next day was that of the hunt and we motored out to the North Shore
Hunt Club. It was a splendid day and the ride was just enough to put an
edge on the meet that was to follow.

We pulled up at last before the rambling colonial building which the
Hunt Club boasted as its home. Mrs. Brackett was waiting for us already
with horses from the Brackett stables.

"I'm so glad you came," she greeted us aside. "Gloria is here--under
protest. That young man over there, talking to her, is Ritter Smith.
'Rhine' Brown, as they call him, was about a moment ago--oh, yes, there
he is, coming over on that chestnut mare to talk to them. I wanted you
to see them here. After the hunt, if you care to, I t
