llivan's men was dangerously hurt. The physician was hurried
out of the house, was driven rapidly north and was never again seen
alive by his friends. This was but three days after the remarkable
contract had been made, and five days after the cards left by the
stranger had been placed in O'Sullivan's hands by the bookkeeper at the
office of the Lake View newspaper. Who was this strange man? How did he
get one of O'Sullivan's new cards? How did he know of the contract? If
he had learned of it through one of the three men who were present at
the time, how did he happen to get one of the new cards? Would he not,
if he had been interested in the removal of Dr. Cronin, have hunted for

Little wonder was it that this remarkable combination of circumstances
directed suspicion against O'Sullivan, especially when it was further
remembered that he was seen in conversation with the mysterious tenants

considered quite as strong, even if not stronger than that against the
detective. Accordingly it was decided to place both men under arrest.
Early on the morning of May 27th O'Sullivan was notified that his
presence was desired at the Lake View Police Station. When he responded

were issued, and shortly before midnight Coughlin was arraigned before
Justice Kersten at the Chicago Avenue Station, to the bar of which the
detective, during his four years of service, had brought many scores of
prisoners. Yet, even in this critical hour, he did not seem to feel his
position, but smiled and chatted pleasantly and in a light hearted
manner, with his former companions on the force. No evidence was
submitted, the prosecution requesting a postponement, and by agreement
the case was adjourned for a week, an application for the admittance of
Coughlin to bail being peremptorially refused. A patrol wagon conveyed
the detective to the County jail and here he was assigned to Cell 25,
in what was known as "Murderers' Row." While these proceedings were
being taken, O'Sullivan, at the Lake View Station, was being closely
interrogated by Captai
