Richard Castle: [turns away quickly] Sorry.
Kate Beckett: NYPD! Stay where you are.Richard Castle: That's a vacuum packer at one o'clock.Kate Beckett: Looks like we've found our murder weapon.Kate Beckett: Have you seen this man?Richard Castle: My partner is crazy and may start firing at any moment.Kate Beckett: Go! Go!Kate Beckett: Semester abroad?Richard Castle: Nah, TV show I used to love.Kate Beckett: Ehn, nice job.Richard Castle: Thanks.
Richard Castle: Looks like she was stabbed with a knife.Kate Beckett: Mmm.M.E. Sidney Perlmutter: To the untrained eye, perhaps. But... what you don't know about postmortem analysis could fill a book, Mr. Castle. In fact, it has. Numerous times.Richard Castle: Fine. So, it was not a knife.M.E. Sidney Perlmutter: Ah, wrong again. It was a knife, but "stabbed" implies the blade was thrust into the victim, uh, whereas this wound was produced by it being hurled into her chest.Kate Beckett: What is this, "Last of the Mohicans"? What kind of knife is it?M.E. Sidney Perlmutter: Uh, one with a hilt that matches these small bruises on either side of the wound. It killed her instantly, severing the left anterior descending artery.Kate Beckett: Okay, so either that's the luckiest knife toss in the world...Richard Castle: Or, she was killed by a circus knife-thrower. Like the Great Throwdini.
