The first sound we hear is a woman panting.

And with that, theres Clue No.

And given her panicked perspective and heavy breathing, she probably wasnt planning to murder someone that night.

On the other hand, maybe even seasoned murderers get a little nervous post-kill.

We get it: The shows trying to tell us women love to kill.

So maybe the killerisnta woman then.

Murder mysteries are all about the tricks, and this feels like a classic murder mystery trick.

Plus, her teenage daughter at one point says, You arent dying, are you?

But shedoesseem like the most obvious choice here, meaning she probably is alive and well by seasons end.

HBO loves a red herring, after all.Is she the killer?Could be!

Ed (Adam Scott)Is he dead?Nah.

Celeste (Nicole Kidman)Is she dead?No, too obvious.

But were smarter than that!

(Also, we hate Perry.

)Is she the killer?Maybe.

She could kill Perry in an act of self-defense (or revenge).

Also, lets revisit this little tidbit: Its Monterey!

We pound people with nice!

Madeline cheerily tells Jane.

To death, Celeste adds.

So shes in the same boat as Perry: not the killer.

Then again, its no fun if we already hate the killer!

Who got murdered?Celeste killed Jane.

Neither are too obvious or too much of a dark horse, making them good candidates.
