Serious Crimes - Frank Tayell

Even after the apocalypse, crimes must be solved.
Strike A MatchThey called them Artificial Intelligences. Sentient viruses were closer to the truth. They spread throughout the world until every networked circuit was infected. Then they went to war. Millions died in the nuclear holocaust that brought an abrupt end to the AI's brief reign of terror. Billions more succumbed to radiation, starvation, and disease. But millions survived, and they rebuilt.
Serious CrimesTwenty years later, a ceremony is being held to mark the first transatlantic broadcast since The Blackout. The Prime Minister of Britain and two of the Presidents of the United States will speak to an audience of nearly ten million people. Not all are celebrating. Crime is on the rise, and power is once again a prize worth murdering for.
Ruth Deering, a new graduate from the police academy, doesn't care about ancient history or current affairs. She only joined the force to escape the smog-infested city. Those hopes are dashed when she is assigned to the Serious Crimes Unit, commanded by the disgraced Sergeant Mitchell. Her first case seems like a simple murder, but the investigation uncovers a counterfeiting ring and a conspiracy that threatens to destroy their fragile democracy.
Serious Crimes is a transatlantic thriller set in a world of rationing and ruins, democracy and despotism, steam trains and smart phones. This is not the story of how the apocalypse is survived, but of what happens next.
