Shadow grabs Harry

Something grabbed me from behind, wrapping around my waist like a soft, squishy rope. I slapped at the car door, but I managed only to slam it shut as I was hauled back off my feet. I landed on the ground near the fire door.
"Harry!" Susan shouted.
"Go!" I gasped. I looked at Martin, behind the wheel of the limo. I grabbed the Shroud and tried to throw it at the car, but something pinned my arm down before I could. "Get out! Get help!"
"No!" Susan screamed, and tried for the door.
Martin was faster. I heard locks click shut on the limo. Then the engine roared, and the car screamed into the street and away.
I tried to run. Something tangled my feet and I couldn't even get off the ground. I turned to find Nicodemus standing over me, the hangman's noose the only thing he wore that wasn't soaked with blood. His shadow, his freaking shadow was wrapped around my waist, my legs, my hands, and it moved and wriggled like something alive. I reached for my magic, but the grasping shadow-coils grew suddenly cold, colder than ice or frosted steel, and my power crumbled to frozen powder beneath it.
One of the shadow-coils took the courier's tube from my numbed hands, curling through the air to hand it to Nicodemus. "Excellent," he said. "I have the Shroud. And I have you, Harry Dresden."
