The 'Black Phantom'. A name when uttered would send chills down the spines of anyone who worked in the underground world. That name was akin to a boogeyman to every rich and powerful individual. No one knew his face or his identity as everyone who met him never lived to tell the tale.
It was said that if the Black Phantom was to target you, you have two choices. Either commit suicide or pray that you get a quick, painless death.
However, in unknown circumstances, that legendary hitman suddenly vanished from the underworld, never to be seen again. The reasons were a mystery and the uproar it created was nothing short of historical.
