Dear Dad,

Is it kind of weird that I'm always writing letters to you, even though we live in the same house? I think that's kind of weird.

Anyway, the wealthy owner of a research facility in Colorado has asked me to investigate a cold murder case. It seems that Niko Jovic, a brilliant researcher, was killed while on the verge of announcing a groundbreaking scientific theory.

The murder weapon? A Tesla coil that Niko was working with. I don't know who this Tesla guy is, but he's at the top of my suspect list now.

I'm calling this case "The Deadly Plot Device". See you soon.

Nancy.
