Punny Pinkie: Perfect Murder

>Another murder.
>This was getting out of hand now.
>Being the third time this month, there was very little time left to find this sicko.
>It's only natural that they would call you, Detective Anon, to investigate.
>Why they made you take the damn rookie Pinkie, you'll never know.
>Something about her is... off.
>Everything's a joke; she never takes anything serious.
>No matter.
>You have a job to do.
"Victim's name is Drawing Board."
>Pinkie whips out a clipboard and begins writing as you look over the corpse.
"Cause of death: multiple stab wounds to the chest from freshly sharpen pencils."
>Grabbing one of the pencils, you lift it up in the air and look it over.
"It's a shame ponies don't have fingers. With a few prints, this case would be a lot easier."
>Pinkie remains silent as you continue to search the room.
>Opening the drawer to the victim's desk, you find a note.
"I know everything about that comic you wrote about me. You won't see the light of day once I get my hooves on you."
>Scanning the paper, you look at the signature.
"The Pie Artist."
>There isn't enough evidence to narrow down who this could be.
>Maybe you overlooked something?
"Hey, Pinks. Got any ideas on this case?"
>"There's only one thing that's running through my mind."
>Turning back to mare, your heart drops.
>She stares back at you with that evil, sinister smile, holding one of the pencils high in the air.
>Before she strikes the killing blow, she blurts out:
>"The details to this murder are sketchy!"
