Notices enemy

The third man out of the car was Marcone himself, a man of medium height and build, wearing a suit that cost more than my car, and he looked as relaxed and calm as he always did. Marcone was criminal scum, but I'll give the rat his due-he's got balls that drag the ground when he walks.
Marcone's head whipped around abruptly, back down the alley the way they'd just come, though neither Hendricks nor Gard reacted with a similar motion. He produced a gun with such speed that it almost seemed magical, and little puffs of frost blazed out from the muzzle of the snow-sculpted weapon.
Hendricks reacted immediately, turning to bring that monster weapon to bear, and tiny motes of blue light flashed down the alley, representing tracer fire. Gard put her shield and her body between Marcone and whatever was at the end of the alley. They hurried into a side door of the building, one that had been destroyed in the collapse. Hendricks followed, still spraying bursts of fire down the alley. He, too, vanished into the building.
