Abe is getting his routine checkup with his nurse at the shop. When she asks about his parent's medical history he says he was adopted. His real parents died soon after he was born. The nurse apologizes and again when she leaves.
The average person is said to have apologized 12 times a day. Often it's to atone for a past wrong, an attempt to heal an old wound. But there are some wounds that can never be healed.
An art dealer Karl Haas is bludgeoned to death with what Henry recognizes as a rare statuette stolen by the Nazis during World War II. Several paintings, presumably also Nazi loot, are also missing. Research reveals Haas's grandfather was a prominent Nazi who was responsible for stealing priceless works of arts. After the war, he changed his name and fled to the U.S. with the stolen treasures. Haas's grandson, Erik, is shocked to learn his great grandfather wasn't fleeing the Nazis, he was a Nazi and that his grandfather might be one as well.
Henry tracked down a highly valuable watch found among the victim's things to a shop in Brighton Beach. The owner tells Jo and Henry that he gave the watch to Karl after he returned a priceless family treasure: A Claude Monet painting worth millions. He says Karl was determined to return all the artworks his father had stolen to their rightful owners. Blood left at the crime scene appears to belong to a long-dead artist, Max Brenner. It's actually the blood of his son, Sam, who did steal back his father's painting, but didn't kill Karl. Sam swears Karl was alive when he left, and on the phone, arguing in German about a Rembrandt. When a man drops by Abe's to get an antique silver tray assessed, Abe has no idea he's speaking to Adam. Adam recognizes Abe's tattoo as being from Auschwitz and says he's "something of an expert" on the subject. Phone records indicate Karl was talking to his banker, Julian, on the night of his death. Julian shows Jo and Henry a vault full of valuable artworks whose rightful owners couldn't be found. Henry does an "autopsy" on a frame from the murder site and determines it had to have held a Rembrandt. He warns Jo not to touch because Rembrandt treated his frame with ingredients that would give you a "nasty rash." Henry realizes that the Julian had such a rash when they talked to him. Jo issues an arrest warrant for the banker, but he - and the entire contents of the bank's vault - are already gone. Henry examines the tray left at Abe's shop and realizes, with a shock, that it belonged to his family and that the mysterious visitor was Adam. He meets Adam at a nearby cemetery and warns him to leave Abe alone. Adam apologizes for his "overzealous" actions.
Jo suspects that Julian is moving the paintings the way the Nazis did: By boat. At the docks, she and Det. Hanson find the bloodied body of Julian inside a shipping container. Due to the sadistic nature of the murder, Henry concludes the person who killed Julian is not the same as the one who killed Karl. Henry realizes that Karl would also have died with his eyes open. That means that someone close to Karl closed them: They arrest his son, Erik, who confesses to killing his father during a heated argument. Julian had told Erik - who was then struggling to pay his rent - the truth about his father's art collection. Erik followed him when he returned the Monet and confronted him. Jo tries to get him to confess to Julian's murder as well but Erik, as Henry guessed, had nothing to do with it. Lucas runs a test on the DNA found on Julian's ring: He tells Henry the killer has similar DNA to Henry's. Lucas thinks this can't be right and decides to run it again. But before he can, the evidence goes missing, right after Henry finds out that Adam shares DNA with the Ice Truck Killer, Brian Moser. which confirms Adam is Julian's killer. Henry can't tell Jo and Hanson that as it leads Henry directly to the Bay Harbor Butcher as well, however, and – for once – professes to have no theory about the murder. Adam returns to Abe's and leaves behind a record book that reveals who Abe's parents were.
Abe finds out he is related to Henry through a Dennis Loanworth who had a kid out of wedlock with Marie Driscoll, Dexter's father's sister.
Maybe Henry will look into his own family tree and discover who his real mother is and what happened to Laura Moser. Jo seems to be getting closer to the truth about Henry in next weeks episode.
The truth is each of us is related, it's just the question of how far back you trace your family tree. Deep down, all of us have shared blood in your veins. All though individual tastes may vary. And if we're all related, all of us have royal blood.
She had already had her suppositions about him. How ok he was with death and dead bodies, like it was...art. She always passed it off as Henry being eccentric, Lucas was as well but not as much as Henry was. Henry always seemed guarded. He even barred her out. She'd seen cops that most people viewed as 'cold hearted' but really they were distancing themselves because in this job you had to pretend.
The death of a young college woman sends Henry and Jo back to the cultural hotbed that was New York in the 1980s. Murder victim Sarah Clancy's fascination with authentic 70's attire is more than just a fashion statement, it is revealed that she had an unhealthy obsession with the past. The investigation ironically leads Henry and Jo back to college professor Molly Dawes (aka Iona Payne, the dominatrix), who taught Sarah in a course on sexual identity. Molly not only agrees to help in the search for the killer, but she and Henry spark a hot, romantic connection.
He wanted her as much as she wanted him but the wound from Abigail's leaving was still fresh.
The fact that Molly was almost killed proved to Harrison that his life is dangerous for anyone to get too close. It would have to be goodbye, for now.
