She slammed into the street and felt hands flipping her over roughly. As she lay blinking, cheek to the rain-damp pavement, dazzled by the spots that swam before her eyes, her arms were yanked back.

She lay on the pavement, fighting to control her heaving stomach. The dead boy lay only a meter or two away, his head leaking blood.
