- Lieutenant Scott: Since you're asking me, chief, I'd say the case is washed up. You haven't got the body; you've got no suspects.
- Dr. Crabtree: You forget the occupants of that house.
- Lieutenant Scott: Ha! A Chinaman ... and three intellectual nuts!
- Inspector Carr: [on the Becks] They'll send 'em to the asylum.
- Dr. Crabtree: Another case like this, and we'll all go to the asylum.
- Grandfather Beck: What's going on here?
- Inspector Carr: You live around here? I'm from the police department.
- Grandfather Beck: Uh, yes; I - I own this property.
- Inspector Carr: Yeah, well, somebody's been using your back alley as a cemetery.
- Dr. Crabtree: Why can't you apply the anthropologist's method to this case? You reconstruct the bodies of prehistoric animals from skeletons, as for instance... Now, why can't you recreate this skull into something resembling its former likeness? Hmmm?
- Dr. David Turet: I think we can... Death robs man of the flesh, but bones remain to guide us.
- Inspector Carr: Well, it's a Chinese puzzle, all right, but we've got to solve it! Come on, let's go.
- Inspector Carr: Well, doc, here's something off the beaten track - a murder, and nothing left but the bones.
- Dr. Crabtree: But how are we going to determine how long it's been here?
- Inspector Carr: I don't know - there don't seem to be any clues. Maybe the medical examiner has some idea about it.
