"SOME mystery!" exclaimed the plain-clothes man. "This is a job for
Dave Morgan."




CHAPTER II

DETECTIVE SERGEANT MORGAN


On Sheffield Avenue, just across from the ball park, where the
"Cubs," Chicago's famous baseball team, has its headquarters, is a
row of apartment houses. One realizes, of course, that these are not
homes of wealth, but they have a comfortable, substantial look,
which somehow conveys the idea that those who live there are good
citizens, typical of the hard-working, progressive class that has
made Chicago one of the greatest commercial cities of the world.

In one of these apartments lived Detective Sergeant Dave Morgan and
his mother. He had located here in the days when, as a patrolman, he
had walked beat out of the Town Hall Police Station, a short
distance away. After his promotion to the detective force, he
remained here because of the convenient location. The elevated
railroad had its right of way directly back of his home, and the
Addison Street station was only around the corner. He could quickly
get to the Detective Bureau or almost any part of the widespreading
city.
