Shadows

The shadows are darkest at night.
The man creeps along, flattened against the wall, hiding in the shadows as he followed her down the street.
The shadows are darkest at night.
He moves gracefully between shadows, waiting patiently. Oh, how patient he was. From all his nights watching her, he knew where she would go, and he waited as she entered an alley, deep in the shadows.
His heart is darkest at night.
She learns this as he attacks, pinning her to the wall and silencing her by viciously tearing her tongue from her mouth and greedily swallowing it whole.
