I Antasized Again

A gruesome murder has occurred in the mansion, leaving only two witnesses. The killer is skilled at concealing their appearance, leaving the Sheriff with virtually no useful information. He’ll have to solve this mystery on his own, using his wits and the clues scattered throughout the location.
Along the way, fate will lead the Sheriff to various places, each adding more arguments to the case. Furthermore, everyone has their own opinion about what happened.
The Sheriff doesn’t care about any of it. He’s not interested in this investigation. But a little bonus, in the form of a large sum of money, compels him to take action. Of course, the girls will never leave him in peace.
