EVELYN: Your taste in hobbies is getting alarmingly concerning, Doctor. Grotesque, even. I don't call poking around in empty graves a particularly healthy pursuit for a grown man.

DOCTOR: Oh, but this empty grave is merely the beginning. I'm looking forward to meeting the two gentlemen responsible. The Williams Burke and Hare, if I'm right, and I so often am.

EVELYN: Burke and Hare! You mean the body-snatchers.

DOCTOR: Yes, I mean the body-snatchers. Come on. I've got a thirst in more ways than one.

EVELYN: But Doctor, you talk about Burke and Hare as though you're looking forward to meeting them.

DOCTOR: Exactly.

EVELYN: But they're criminals!

DOCTOR: Undoubtedly.

EVELYN: Murderers!

DOCTOR: Absolutely. But maybe not yet.
