Colosse has had an unusual dearth of homicides lately. It went a full twelve days between homicides. Reporters are scratching their heads seeing if they can see if a record has been broken. Then, of course, a murder happened.
It makes me think of those chalkboards with “There have not been any accidents in __ Days.” Somewhere, I can imagine a secretary or an officer erasing the 12 off a chalk board and replacing it with a 0.
