Tragedy, a new victim, a noble and respected man, right on the main street! A lot of people, a lot of panic and, presumably, a lot of witnesses... But no. No one saw it. Neither the criminal, nor the murder itself... Only a corpse, over which the killer also managed to mock, as if challenging and mocking detectives and policemen.

The street was empty, leaving room for only one detective, the best of the best, who bending over the corpse, unsuccessful trying to find at least one clue.
