For a woman who’d had less than four hours’ sleep in the past thirty, she thought she looked pretty good. But then, she thrived on the dangerous edge. Even when life was on a smoother track, she took corners on two wheels: office/gym/office/wine bar/office/home was a typical day, and sleep was never high on her agenda. Sleep was ceding control. While you slept, anything might happen. It might while you were awake, too. Her agent, Alan Black, was dead; killed by the Voice of Albion thugs. Any other operation, and that would be it: the whole house of cards would have folded. There’d be an inquiry. When an agent died, there was a ripple effect. Sometimes the splash was so big, careers were washed away.
