This is an extract from toward the end of Stains, and it's long because ... well, if the excerpt has to build tension, it needs the word count, because tension is about pace and beats and dwelling in the moment so long the reader's itching for the tension to spring.
Of course, the tension in this excerpt also builds upon the earlier parts of the scene, the previous chapters, and everything else established about Levi throughout the story (basically, he's a volatile psychopath with god-powers)
“Your face!” Ella clutched her stomach, her hair spread like wings across the condensation inside the shop window. It left spiderwebs trails in the mist. Gossamer thread sprung from Cain’s fingertips as they played across her skin – silken strands walked up her arm, pianist caresses of her throat, and gently, so gently, pulling back the lids of her eyes.
They’d go as white as his if Cain lingered there too long. White as the moons they made tracing the charming laughter on her face. White as the needles of his teeth limning the indulgence of his smile.
My Cain. Casper drowned on it. Ruinously slow, his chest wrenched itself apart. My Cain.
“It’s your fault!” Open-palmed, she slapped the table, her scream high and heady through the music’s psychedelic slur. Tears slipped over cherub cheeks in black droplets. “He only left because of you. If it wasn’t for you, I wouldn’t have to—”
The bathroom door slammed open.
Kinda like a snap second eternity of a lucid dream, Levi hung in the doorway. Knife-edge smile as he forced his hands into the sides of the arch like he could snap it, bring it down. Static pricked the air around him, scratches of white noise carved out of the atmosphere as he took in the room.
His dead-ice eyes met Casper’s with a shock of cold, and slowly, deliberately, he placed his fingers to his lips and winked.
Some dim, drunken part of Casper’s mind noted Ella still raved, but Levi absorbed him. The prowl, the sway of his hips in those plastered leather jeans. Out to his sides, his fingers flexed, snares of white electric arcing between the glimmering gold of his rings.
The precision of each action peeled back Casper’s skin, nooks at the joints to let the bugs in. And they burrowed through muscle and flesh to gnaw at the core of his bones.
A step away from Ella, he lunged.
