O'Brien's Stand

Malloy's fiesty landlady, Mrs. O'Brien, has her purse stolen and refuses to leave the station until her case is settled. O'Brien resorts to other means, including hounding detectives and setting up a picket line to vent her frustrations. Malloy determines that there may be a connection between O'Brien's theft and a string of purse snatchings involving Social Security checks, and suggests using a decoy to put an end to the heists, which works and the ring is brought down. Another incident involved two men arousing suspicion for their erratic behavior; in the ensuing pursuit the men are arrested and heroin is found in their car; later a call to a home where a man killed his son with a shovel, during the murder investigation they find candy wrappers and tire tracks that link with the two men arrested earlier.
