I'll be leaving now.
Don't overdo that cocaine and morphine.If you say that's how it is, then it's certainly so.Ah, goodbye, Witch of the Spring Haze.That's what I feel.I see...Yeah, goodbye, Detective.Jack the Ripper will make it so.So then-Oh, is that right? I don't think so, but-Simply, this is likely the last time you and I will speak.Even if I were to leave this cityI used the information you gave me in my search,That's not surprising.I've been quite the popular person for a while.It's that time, isn't it....Well,Did you find what you're looking for?Why? At a time like this?Is that right? But you won't disappear.You would still be here, smoking in your apartment on Baker Street.The old ones leave, and new ones like you come to take their place.But unfortunately, I didn't find anything.
