Interrogation room. Cahill explains that he's wiped out and keyed up after a shift, so he can't sleep without the morphine. Holmes isn't all that interested. Anyway, a couple months ago, he snuck into a room that turned out to be an Angel's victim. He snuck into the bathroom to... Holmes interjects: "I believe the words you're looking for are 'shoot' and 'up'." The way he says this is very Blackaddery. I think it's the way he enunciates the "p" in "up." If you're wondering why I gave this episode such a high grade, it's because there have been a lot of little moments like this that I've really enjoyed. The show overall is still a standard procedural that uses the name Sherlock Holmes, but things like that can make it stand out for me.
Anyway, when Cahill went to leave, he saw someone coming into the room. He didn't recognize the guy's voice, but he and the patient talked for an hour. The doctor went into detail about how the patient was going to die. Gregson sneers that Cahill needed a new morphine source, which makes Holmes glare at him.
Holmes and Watson! Talking things over! Holmes says that the Angel's approach as described by Cahill is exactly like the one perfume-lady described. So they know more about his methods!
Back to the hospital, but only with Watson. She asks Carrie to run a better test for endocarditis, because the one that Morgan passed is only accurate 75% of the time. Carrie won't do it. Watson says if she operates on her, she could die. Carrie: "She'll be fine, Joan. I'm operating on her. Not you." Now the charitable way to read that is, "It's my decision. Not yours." But given that we know Watson accidentally killed a patient, it seems like Carrie could be saying, "I'm doing the operation. Not an incompetent like you."
Watson joins Holmes. He's interested in her results! I like that a lot, actually. He is disappointed in her giving up and then he dismisses the entire thing from his mind to return to the matter at hand. He has a form from one of the victims. And it features two handwritings! Inichka Jones had to fill it out for the Ukrainian patient, meaning that this victim spoke Ukrainian and not English. And the Angel must have talked to her, because that's what he does. None of the doctors at the hospital speak Ukrainian, but, says Holmes, not all doctors stay doctors.
In the interrogation room: it's the janitor! He had blue and yellow rags on his cart. He admits that he used to be a doctor in the Ukraine, but now he's just a janitor. Holmes and Gregson lay out the victims. "We believe they were all murdered." The janitor admits that he remembers them. "When a patient is in pain, dying is not a tragedy," he says. Gregson says they had a warrant, so they searched his apartment and found a log of notes about precisely these nine patients. The janitor says he "freed them" after confirming for himself that they had no hope of recovery. Holmes asks about the one they found who was getting better, but the janitor doesn't understand: "Better? People do not get better from metastasized cardiac cancer." Holmes says she didn't have cancer, but the janitor insists they found a mass and she was dying. Also that Holmes is making up lies, just like the police in the Ukraine.
