Gunshots, a fleeing van and a massive blood pool all point to murder, but when Castle & Beckett arrive at the crime scene, they discover that it lacks something - the victim! The investigation leads to the cutting-edge world of life-extension science, a cunning high-tech researcher, and a sleazy porn mogul who invested in a modern-day "fountain of youth."

Meanwhile, Alexis finds out whether she got into Stanford.

Trivia--Cynthia's suicide at the end would not have been possible if she were being held at an NYPD police station. It is standard procedure to confiscate and store all a detainee's personal effects, including all rings (even wedding bands), jewelry, belts, and every object in their pockets. Her ring would have been removed during the booking process and would likely have been examined for a hidden capsule.

  • Weiss's cryonics company technically violated the law by moving the body in the first place, and could be charged with a crime under New York's Penal Code § 195.05 "Obstructing governmental administration in the second degree." As such, the legal wrangling in the episode to get the body would never have been necessary.


There are two kinds of folks who sit around thinking about how to kill people. Psychopaths and mystery writers. I'm the kind that pays better. Who am I? I'm Rick Castle. Every writer needs inspiration. And I found mine. And thanks to my friendship with the mayor, I get to follow her around. And together we catch killers.
