Culverton Smith
- Culverton Smith: If the Queen was a serial killer, I'd be the first person she'd tell. We have that kind of friendship.
- Culverton Smith: What's the very worst thing you can do... to your very best friends?
- Ivan: Something on your mind?
- Culverton Smith: Yes, Simon. Oh yes.
- Ivan: Whatever you tell us, stays in this room. I think I speak for everyone.
- Faith: Well, what is the worst thing you could do?
- Culverton Smith: Tell them your darkest secret. Because... if you tell them, and they decide they'd rather not know, you can't take it back. You can't unsay it. Once you've opened your heart, you can't close it again.
- Culverton Smith: Murder is a very difficult addiction to manage. People don't realize how much work goes into it. You have to be careful, but if you're-you're rich or famous and loved, it's amazing what people are prepared to ignore. There's always someone desperate about to go missing, and no one wants to suspect murder if it's easier to suspect something else. I just have to ration myself, choose the right heart to stop.
- Sherlock Holmes: Why do you do it?
- Culverton Smith: Why do I kill? It's-it's not about hatred, or... or revenge. I'm not a dark person. Killing human beings...
- [starts chuckling]
- Culverton Smith: ...it just makes me... ah, incredibly happy. You know, in-in-in films, when-when you see dead people pretending to be dead, and it's just living people lying down? Well, that's not what dead people look like. Dead people... look like things. I like to make people into things. Then you can own them.
- Culverton Smith: Oh... no, I-I'll lay it out for you. There are two possible explanations for what's going on here. Either I'm a "serial killer" or Sherlock Holmes is off his tits on drugs, hm? Delusional paranoia about a... a public personality. That's not so special. It's not even new.
- Culverton Smith: [turns to Sherlock] I think you need to, uh, tell your faithful little friend how you're wasting his time because you're too high to know what's real anymore.
- Culverton Smith: Please, please, no violence. Thank you Doctor Watson. I don't think he's a danger any more. Leave him be.
- Sherlock Holmes: No, no it's OK, let him do what he wants, he's entitled. I killed his wife.
- Dr. John Watson: Yes you did.
- Culverton Smith: All I'm doing, Faith dear, is getting something off me chest without getting it on yours.
