Friday afternoon, and the traffic is bloody murder. Sergeant Belinda 'Billy' Kidd is driving home from the airport, jet-lagged and ready to resign from a career that has left her traumatised. Menopause has robbed her confidence too - now she's a traffic cop who's afraid to drive. When brake lights haemorrhage up the motorway, the cars grind to a halt. Moments later she finds a dead driver in a black sedan. He has a metal skewer in his neck. But how? The killer can't have left the scene without being spotted by the dozens of witnesses - so he must still be there, among them. If the traffic jam stays put, they're all in danger; if the traffic clears, she'll lose her suspect. The clock is ticking, but she doesn't know how fast.
