e one in the city; but the facts of the case
plainly indicated that the assassin was an "outsider," and even Jourdan
and Kelso were at a loss to know how to proceed to find him.

At the time of the murder, the only inmates of the house were Washington
and Frederick Nathan, sons of the dead man, and Mrs. Kelly, the
housekeeper, and her grown son, William Kelly. Had the murder been
committed by any of these they must of necessity have stolen the missing
articles, and as they had not left the house, must have destroyed or
concealed them on the premises. Without the knowledge of these persons,
Jourdan caused a rigid and thorough search of the house and lot to be
made from cellar to garret. Every crack and crevice, every nook and
corner was rigidly and minutely searched by experienced persons. Even
the furniture and carpets were examined, the flooring of the stable was
taken up, the water-tank was emptied, the basins, closets, and
waste-pipes of the house were flushed, and the street-sewers were
examined for a long distance from the house, but no trace of the missing
articles could be found; nor could any mark of the "dog" be discovered
anywhere save on the body of the victim. One by one, the inmates of the
house were subjected to the most searching cross-examination, and within
six hours after the discovery of the deed, Captain Jourdan was satisfied
that the inmates of the mansion were entirely innocent of the crime. The
evidence drawn out by the inquest subsequently confirmed the innocence of
these parties.

The only clew left by the assassin was the "dog." At the inquest, the
policeman on the beat swore that when he passed the house on his rounds
at half-past four A.M., he tried both front doors, and that they were
fastened, and that when he passed again a little before six o'clock, he
noticed that the hall-door was closed. Another witness testified that
about five o'clock, a man in a laborer's dress, carrying a dinner-pail,
ascended the steps of the Nathan mansion, picked up a paper from the
topmost step, and passed on down the street. The introduction of this
man in the laborer's dress but deepened the mystery and increased the
labors of the Detectives.

The entire police force of the city was set to work watching the
pawn-shops and jewelry stores where the thief might try to dispose of the
stolen property. Every ship-yard and boat-yard was searched for the
identification of the "dog," but without success, a
