A flight from London to Dublin arrives carrying an unusual cargo – a passenger stone-cold dead in his seat. Sergeant Fiona Moore immediately suspects foul play and forensics confirm a lethal cocktail of drugs was in the man’s system. But Moore is left to largely tackle the case herself as her immediate boss, DI Aidan Burke, has other things on his mind – namely the attractive Swedish co-pilot, Andrea Bergin. Investigating the victim’s business dealings and personal life, Moore finds that all was clearly not quite well with the successful lawyer. Yet who was driven to kill him and what do they want to hide?
