In London the roads could be unexpectedly congested at any time, but this Saturday morning her journey was relatively fast. Her easy drive didn’t improve her mood. The senior crime command centre was already humming with quiet activity. After checking her emails, she made her way along the corridor to find Sam who had a team of constables still looking for the missing van driver. ‘He must be somewhere,’ Sam insisted. Trying to appear decisive, she sounded plaintive. ‘People don’t just disappear into thin air.’ Most of the team were convinced it must have been Piers, his son’s alibi having checked out. No one could explain how he could have been driving the van and escaped from the crash alive. In the absence of any other information, they were working on the assumption that whoever had been driving the van had also committed the murder. ‘It seems highly unlikely that someone else appeared on the scene after the crash and killed Anna,’ Reg pointed out, ‘but we need to keep an open mind.’ ‘You mean two people might have disappeared?’ Sam said.
