- Steve Ramsey: [nastily] Insanity doesn't run in your family; it gallops!
- Lucy Ramsey: [angrily] I hate you. I wish I never married you!
- Steve Ramsey: But you did! Because you like what Steven does to you, don't you, my sweet little chicken?
- Lucy Ramsey: Bastard!
- [she slaps him and walks away]
- Michael Rycroft: [standing over dead body on autopsy table] You're right. He was electrocuted.
- DCI Tom Barnaby: Whatever happened to good old-fashioned shooting?
- Sgt. Gavin Troy: [sarcastically] Maybe this is the new green way to zap your victims - no blood, no guts, just fried brains.
- Sgt. Gavin Troy: The wheat in the circles was burnt by butane gas. It comes in cylinders for gas blow torches. You can get it at any DIY store.
- DCI Tom Barnaby: [ironically] Oh, not some derivative of kryptonite from the planet Zog?
- DCI Tom Barnaby: What's your opinion of Lloyd's beliefs, Lady Isabel?
- Lady Isabel Aubrey: All men are credulous animals.
- Lady Isabel Aubrey: We must all believe in something.
- Sgt. Gavin Troy: UFOs and ETs, sir, how did we get shunted into this siding?
- DCI Tom Barnaby: A suspicious death, Troy. And if we want to keep our pensions, we'd better find a better reason than that for Ronnie Stokes' death.
- DCI Tom Barnaby: [last lines] Hey, look. The Mekon, now that was a real alien to me when I was a kid. Every night - every night before I turned out the light I used to look under the bed, see if he was there to capture me, carry me off to some God knows what galaxy, other side of the universe.
- Joyce Barnaby: What are you gonna do with these?
- DCI Tom Barnaby: Well, saved 'em for Cully. It's boys stuff, isn't it, really? Think I' just bin the lot.
- Joyce Barnaby: Oh no, you don't. These'll fetch a fortune at Causton Charity Shop. UFOs are all the rage around here. Or didn't you know?
- Lloyd Kirby: How you goin' to arrest an extraterrestrial then?
- DCI Tom Barnaby: If they're guilty, everyone has to come back down to Earth.
- Sgt. Gavin Troy: [sarcastically] And in your case, Mr. Kirby, it'd be a very large bump.
- Sally Boulter: You know, the first one was electrocuted!
- Sir Harry Chatwyn: Electrocuted?
- Sally Boulter: Cooked inside like a steak and kidney pie!
- Lloyd Kirby: This has nothing whatever to do with extraterrestrial forms of life.
- DCI Tom Barnaby: I agree with you, Lloyd. This is murder.
- Beatrice Chatwyn: [contemptuously] I hope you'll rot in Hell!
- Sir Harry Chatwyn: I probably will, but I didn't kill Lloyd.
- DCI Tom Barnaby: Hello Troy. You're just in time. About to push the boat out.
- Sgt. Gavin Troy: Evening, Mrs. Barnaby.
- Joyce Barnaby: Evening, Gavin. I get the feeling this is one of those "Tom can't have another drink " moments. Is that it?
- Sgt. Gavin Troy: Afraid so. Another body's been discovered, sir, in a second crop circle.
- DCI Tom Barnaby: Another one?
- DCI Tom Barnaby: What about his hair? Look, there's a chunk cut out.
- Sgt. Gavin Troy: Looks like he's been to my barber, sir.
- DCI Tom Barnaby: Thank you, Sergeant.
