Looking for a place to invest a $5,000 windfall, Lou gets a shocking look at white collar crime when he uncovers a clever financial scheme run by a sharp con man. He learns there are shady characters only too willing to put his money in their pockets, but has trouble convincing at least one victim ? Charlie Hume ? of what's going on.

The city is thrown into panic when the Tribune's star columnist writes a column that Lou fears could incite a serial killer to strike again. The reporter who covered the so-called "Samaritan" slayings years before is assigned to draw up a profile that might lead to the madman, and the staff fans out to follow his clues.
