Delko laughs, since this means Leo Kling -- the guy he was talking to by the pool -- was right about Betty changing her will. Calleigh insists, "Pearl Abrams did not kill her sister." Delko shoots back, "Yeah, well, somebody did."

And now, we go back to the Miami version of The Weakest Link. It turns out he's also the newly dead link, as Horatio notices Kimble slumped over in his car. "Paging Dr. Wilmont," he says darkly. He and Speedle continue to look down at the body, and Horatio notes, "Cluster wounds, right on the money." "He didn't even have time to fight back," Speedle says. Horatio gives another lesson in crime-scene reading by replying, "That's right -- because he was sitting with somebody he trusted, wasn't he? You know what? Get the Bullard." I love how these guys just whip out these gadgets whenever the mood strikes; no doubt, one of these days, Horatio's going to be all, "Speed, get my magic wand and fairy dust," and Speedle will.

Next thing we know, Speedle's waving around something that looks like a Black & Decker handsaw and telling Horatio about the relatively recent body heat imprint on the seat. They're able to determine that the murderer braced himself for the stabbing, based on the strength of the heat imprint in the legs relative to the rest of the body, and they find a big blank spot in the back. Horatio looks at the square and says, "What the hell is that?" Speedle replies that he's going to take the image back to the AV lab and try to enhance it.

Back at the B-plot, Delko and Calleigh -- who, by the way, have quite an enjoyable working chemistry -- are in Betty's bedroom. Delko's crouching on the floor and Calleigh's pacing around, saying, "When you've eliminated all the suspects and the evidence doesn't make sense, it's nice to put it in context." Delko begins thinking out loud: "We know all this blood is Betty Rosen's." Calleigh replies, "So we reevaluate the 'how' to get us to the 'who.'" Or go back to minute three of this episode, when you segued to the credits. Anyway, Delko and Calleigh proceed to string the apartment, mapping each blood spatter in an effort to create a tangible map to find the point of origin. Then they walk it:

Delko: Spatter starts high.
Calleigh: Consistent with beginning of attack. Blunt force object -- the countertop.
Delko: Right. Now, she turned and fell, laying here for a while where she created this blood pool. At some point she got up, moved down the hallway, to here.
Calleigh: Another blow area. Blood smears here.
Delko: There's another spatter pattern here on the table, where, again, she fell to the ground.
Calleigh: Making another pool of blood.
Delko: [walking into the bedroom] The spatter in this room radiates in a complete circle.
Calleigh: Leaving no space for anyone else to be in the room.
Delko: All this blood...unable to move...I guess she laid there until she died.
