Murphy's Law is the 4th chapter in Mafia II.
Narrative[]
February 11th, 1945
The Plan[]

Joe explains the job
Vito wakes up to find a note from Joe that says to meet him at Freddy's with a gun and some lock picks to talk about a big job he has lined up. At the bar, Henry Tomasino explains that a guy who borrowed money from Alberto Clemente to buy a jewelry store isn't paying him back fast enough. The plan is for Vito and Joe to rob the jewels by sneaking in after dark dressed as phone company employees.
The Job[]
Later that night Vito and Joe go to the mall and rob the store, but as they were finishing the job Brian O'Neill and his gang drive a van through the window in order to rob the place themselves. Just as the two groups begin firing at one another, several police officers show up and everyone scatters to get away. Caught between the police and the O'Neill gang, Vito and Joe head to the roof and make their escape by crossing over to a neighboring building, reaching safety just in time to see the O'Neill gang being arrested.
Walkthrough[]
The Robbery[]

Joe and Vito run into Brian O'Neill
Get dressed and head out of Joe's apartment. Before you go outside, head all the way down the stairs until you reach the bottom, where Playboy magazine #7 is on the ground. Drive to Freddy's and listen to Joe and Henry lay out the plan, then get in your car with Joe and drive to the mall. Follow your map icon to the glowing door where you will need to pick the lock, then watch the cutscene of the O'Neill Gang busting in and the police showing up.
The Escape[]
Once you gain control, follow Joe through the mall and cover him while he picks the lock on the stairwell door. As you go up the stairs you will find Playboy magazine #9 on the first landing by a box of books. Immediately after that, turn left as you go through the door and you will find Playboy #2 under the stairs.

Watching the O'Neill gang get arrested
Continue up the stairs and cover Joe as he picks another lock, then head out onto the roof. Continue following Joe, fighting off the police as you go, until you enter a rooftop structure. In there you'll find Playboy magazine #8 on the floor. Once you're back on the ground and have seen the police arrest the O'Neill gang, turn right as you leave the alley and steal a car to get away. You'll have a wanted level, so you can either head to the nearest clothing store and change or just drive back to Joe's place and end the mission, where you will receive the Night Shift achievement.
News Report[]

Trivia[]
- The title of this chapter is a reference to Murphy's law, which states, "Anything that can go wrong, will go wrong".
- If Vito doesn't have any weapons at the beginning of the chapter, he will be prompted to buy one at a gun shop before meeting Joe at Freddy's.
- You can pick up a Thompson 1928 from the mall security who guard the hall by the bookstore.
- Attempting to explore the mall immediately following the cutscene will result Joe being killed. And attempting to do so later will result in officers spawning right next to you and gunning you down in instant even on easy mode.
