Polygraph

"Like most bad ideas, it started with alcohol."

When a vicious serial rapist terrorizes the Bay Area, lowly beat officer Lukas Richter knows he can help. It’s said he can see through your skin and is more effective than a polygraph at detecting lies, which might seem like it would be a killer talent in law enforcement. But when a drunken boast has Richter seeing something he shouldn’t, he will be sorely tested: Does he have what it takes to make it in the SFPD --- or will his career dissolve before it even starts?

If this short story were a movie it would be rated R for hard language and intense violence.
