'Alcatraz' - 'Paxton Petty' Recap

As the latest episode opens, a young Hauser is transporting a prisoner to Alcatraz. This prisoner is former war hero Paxton Petty, being put away for a series of bombings. While Petty is being handed over to the warden, Hauser gets his first look at Lucy (or Dr. Sangupta, as everyone called her on the Rock in the 60s), who in the present day is still unconscious from the sniper bullet she took in the second episode.

Also in present day San Francisco, three bombs go off in a park, killing a few and wounding many others. When Madsen arrives, she glances over the crowd and sees Petty without knowing it. Doc and Hauser get a look at the bombs only to see that they're old military issued land mines, Petty's MO.

Madsen takes a look at his picture on Doc's iPad (because everyone just carries one of those around everywhere) and realizes that she just saw him. She chases after Petty, and when she thinks she has him cornered, Petty rolls a mine down the street toward her, exploding when it hits a car.

Doc and Madsen go to the lab at the police station to see if they can make sense of the metal they found in the mines. It looks like it has designs on it, stars maybe, and that these could be military medals. Our team brings the scrap to a guy who I presume was in the military and tells Madsen that it's a Silver Star. Madsen also worked out that Petty worked graveyard duty while in military prison, and that's where he was getting the stars from.

In a flashback, the warden, Dr. Beauregard and Lucy are attempting to interrogate Petty on the location of another bomb. Beauregard's tactic of dunking Petty in an ice cold tub isn't working, so Lucy goes with electroshock therapy. A dazed Petty starts singing a Korean lullaby.

Lucy calls Tommy Madsen into her office, knowing he also fought in Korea. She asks him why Petty would be singing that lullaby, and Madsen tells her that the locations of mines were hidden in the lyrics.

In the present, Hauser is looking at Lucy's old notes, all of which seem to by song lyrics, in an attempt to find the next bomb.

Madsen and Doc go to the cemetery where Petty was assigned for work detail and find his stash of bombs and other supplies, along with a dead security guard, in one of those walk-in tombs. They find sandstone colored paint and playground turf, expecting the target to be a schoolyard park.

Hauser finds a clue in one of the songs he's looking at and sends Madsen to the location. Hauser also finds another location in the song, and goes there alone. He arrives at a beach to find Petty planting a mine, but steps on another one that was already planted.

Madsen and Doc are still at the school, bored, but spring into action when Petty finally shows up. Madsen gets the drop on him, and arrests him. He realizes that Madsen and Hauser work together, and when Madsen calls Hauser's phone, it starts ringing inside Petty's bag.

Madsen and Doc lock up Petty in Alcatraz while she tries to figure out where Hauser is. She goes into their HQ and sees a file showing that the Petty case was Hauser's when he worked for the San Francisco Police Department back in the 50s and 60s. She sees on the computer that Hauser had searched for a beach, then she remembers the sandstone paint.

Another flashback occurs after Petty tells Doc that he was important on Alcatraz back in the day, that the warden and the "lady head shrinker" thought so. Doc refutes that there were any female doctors on Alcatraz. Apparently, Lucy was never officially on the island.

Madsen, Doc and Madsen's bomb squad friend Tanner get to the beach where Hauser has been standing for a couple hours now. Tanner tells Hauser to get off the bomb and book it for cover. He seems very confident that the bomb is defused, then it goes off, killing him. Hauser tells Petty a good man died today, and shoots Petty in the leg, then drives away while he writhes in pain.

Hauser goes to visit Lucy in the hospital and tells her that he finally found the last bomb from when Petty had originally been sent to Alcatraz. Then he unplugs all her instruments and takes her out of the hospital and brings her to the underground Alcatraz replica. He puts her on the table and tells Dr. Beauregard, "You know her methods. Fix her."
