I Know What You Did

Prologue

As the masked figure approached, the group trembled. His knife shone like a star in the abyss and they knew there would be no return for them.
His shadow stalked the silence, inspecting each one of its victims.
With one fell swoop, she was on the floor, blood collecting around her lifeless body while all the rest of the room could do was stare.
Another looked up at the ceiling, praying to whichever god would listen. But within a heartbeat, a thick stream of red liquid cascaded from his throat and he too joined the lifeless inferno before his prayer could be answered.

Within a matter of minutes, the entire party had succumbed to the attacker's knife. He marvelled at the chaos he had created and smiled to himself, knowing that tomorrow would bring the same atrocities.
He removed his mask, cleaned the blood from his clothes and locked the door behind him before returning to the ordinary world. Nobody knew what was hidden from view, nobody knew who wandered the streets beside them. But he did.
He turned into an alleyway, assessing the fasted way to the town centre. He did not see the blonde ponytail flash before his eyes. He did not see the slim, hooded figure behind him. All he saw was the inside of his eyelids as he crashed to the floor.

Soon, the entire world would know of the mysterious mass murderer stalking the silent streets at night. All except one man.
