Strong Kitty

It is May, three months before the killings. Maggie is sleeping with Andrew in his workshop, and when she tells him she is pregnant he gives her money to deal with it. That night she takes something to end the pregnancy, and Lizzie stays at her bedside through the miscarriage while Maggie tells her the darker parts of the countess's story. The secret binds them.

The episode also shows Lizzie's own body as a source of pain and shame, which Maggie treats with a frankness no one else in the house offers. Emma accepts a proposal she privately plans to break off. Lizzie learns how large her father's fortune is and how little of it he means to leave her, because he thinks her feeble-minded. At a matinee of A Midsummer Night's Dream she is dazzled by the actress Nance O'Neil and invites her to dinner.

Then Abby, maddened by the cooing, takes an axe to the dovecote and kills every bird. Lizzie, covered in feathers and blood, begs her father to show that he cares, and he tells her not to burden him. She walks into Maggie's room and says they are going to kill them. Their first method is oysters left to spoil in the May heat, served in soup. Andrew and Abby are violently sick through the night and survive. In the morning Lizzie looks at the axe Abby used on the birds and decides that is how it will be done.

The illness has a real source. In the days before August 4, 1892, Andrew, Abby, and Bridget were all sick, and Abby went across the street to tell Dr. Seabury Bowen she feared they had been poisoned. He thought it was spoiled food in the summer heat. A druggist later said Lizzie had tried to buy prussic acid the day before the killings, but the judge excluded that evidence at trial. The series turns those scraps into a deliberate, failed poisoning in May.

The doves are a reversal. Lizzie kept pigeons, and the account usually told is that Andrew, not Abby, killed them in the barn after break-ins. The money is reshaped too: Andrew's estate was large — estimates run to about $300,000 or more — but he left no will, and after the acquittal Lizzie and Emma inherited it. The pregnancy, the affair, Emma's engagement, and the inheritance split are inventions. Nance O'Neil was real, but Lizzie befriended her around 1904, long after the trial.

Strong Kitty is where the series commits to motive. The real case never produced one the jury accepted. The show supplies several at once — humiliation, money, a dead flock, a father's contempt — so that by the time the axe appears, the question is no longer whether Lizzie could do it but when. That is the season's biggest departure from history, and it starts here.
