When Castle casually brings up the time his partner in crime-solving was shot, Beckett sticks to her claim that the entire day is a blank. We know that’s not true. Now we’re starting to believe that perhaps Castle may be thinking that, too. But there’s no time for further speculation, as a pesky murder mystery has just popped up.
College student Jane Herzfeld was shot to death and buried in concrete. A crucifix is found clutched in her fist. It’s as if she was praying, as she knew she was going to die. Jane’s ex-boyfriend, Finn McQueen, did time for drug possession. This may explain traces of cocaine residue found on the victim’s body. The guy also works in construction. Sounds like a concrete lead! Too bad Finn alibis out.
Beckett is beyond frustrated when ballistics reveals that the bullets used to kill Jane came from a gun that’s in their system. That’s the good news. The bad news is that the weapon belongs to one of the cops investigating the murder: Detective Kevin Ryan.
The gun in question was taken by Jerry Tyson; better known a serial murderer dubbed the Triple Killer in “3XK.” Castle tries to tell Ryan isn’t responsible for Jane’s death just because it was his gun. The detective doesn’t buy it. Ryan’s anguish has Castle believing that he’s been “play-acting” as Beckett’s partner. In truth, he doesn’t really know what it’s like to be a cop.
