“Lie detector”

Blood flows in the face indicate certain emotions. Rage is one pattern, confusion another, fear (perhaps of getting caught in a lie) yet another. Some cameras could detect subtle changes in face color from the blood flow, but better yet were cameras that reached into the infrared, to see the heat of that blood flow.

Trish first loved the science of this technology, but after she was denied tenure for lacking funding, she found a new purpose to it. Business.

With google glasses so common as they were, it wasn’t much of a trick to fit hers out with the additional infrared range camera and write the code to show the blood flows overlaid upon their face. She became a human lie detector, able to fox out the lies and bluffs of all but the sociopathic (who incidentally had their own telltale patterns). Perhaps the preponderance of the sociopathic shouldn’t have come as a surprise, but it did.

Still, the funding came in now, and she started up a company. Not with her own special technology, of course. It was her ticket to a bright future. Some other good but less phenomenal idea.

That was, until the meeting with Ms. Teller, who seemed oddly apt at dissecting Trish’s own lies and sidesteps. Reading up on her, Trish discovered Teller’s background in pattern processing and optics. Suddenly, the marketplace had grown just a little more crowded.

To Trish, the solution was obvious—she had to destroy Teller or join with her.
