A piece of evidence that almost is nearly irrefutable. It's origin is from a Sherlock Holme's story and it references how a gun smokes directly after being fired. Therefore if somebody is suspected of shooting a person and they having a still "smoking gun" in their possession, it's evidence that is pretty hard to deny.
