So I sat in the car and didn't really watch as Debs stalked up to the door of the place and rang the buzzer. It was only out of the uninterested corner of my eye that I saw the door open, and I barely noticed the boring detail of Deborah showing her badge. And so I couldn't really tell from where I sat unwatching in the car if the man hit her and she fell over, or whether he simply pushed her to the ground and then disappeared inside.

But I became mildly interested again when she struggled to one knee, then fell over and did not get up again.

I heard a distinct buzzing in Alarm Central: something was very wrong and all my huffishness with Deborah evaporated like gasoline on hot pavement. I was out of the car and running up the sidewalk as fast as I could manage it.

From ten feet away I could see the handle of a knife sticking out of her side and I slowed for a moment as a shock wave rolled through me. A pool of awful wet blood was already spreading across the sidewalk and I was back in the cold box with Biney, my brother, and seeing the terrible sticky red lying thick and nasty on the floor and I could not move or even breathe. But the door fluttered open and the man who had knifed Deborah stepped out, saw me, and went to his knees reaching for the knife handle, and the rising sound of wind that whooshed in my ears turned into the roar of the Dark Passenger spreading its wings and I stepped forward quickly and kicked him hard in the side of the head.

He sprawled beside her, face in the blood, and he did not move.

I knelt beside Deborah and took her hand. Her pulse was strong, and her eyes flickered open. “Dex” she whispered.

“Hang on, sis” I said, and she closed her eyes again. I pulled her radio from its holster on her belt and called for help.

A small crowd had gathered in the few minutes it took for the ambulance to get there, but they parted willingly as the emergency medical techs jumped out and hurried to Deborah.

“Whoof” the first one said. “Let's stop the bleeding fast.” He was a stocky young guy with a Marine Corps haircut, and he knelt beside Debs and went to work. His partner, an even stockier woman of about forty, quickly got an IV bag into Deborah's arm, sliding the needle in just as I felt a hand pulling my arm from behind.

I turned. A uniformed cop was there, a middle-aged black guy with a shaved head, and he nodded at me. “You her partner?” he asked.

I pulled out my ID. “Her brother” I said. “Forensics.”

“Huh” he said, taking my credentials and looking them over.

“You guys don't usually get to the scene this fast.” He handed back my ID. “What can you tell me about that guy?” He nodded to the man who had stabbed Deborah, who was sitting up now and holding his head as another cop squatted beside him.
