Epictetus

Imagine the universe as a forest, patrolled by numberless and nameless predators. In this forest, stealth is survival – any civilisation that reveals its location is prey. Earth has. Now the predators are coming. Crossing light years, the Trisolarians will reach Earth in four centuries' time. But the sophons, their extra-dimensional agents and saboteurs, are already here. Only the individual human mind remains immune to their influence.

British politics is broken. Anyone sitting down to watch the news will get a firm sense that something has gone terribly wrong. The MPs we get are of the lowest imaginable quality. The voting system doesn't actually count the votes. The government is in charge of scrutinising itself and takes a predictably light-touch approach to doing so. Ministers are misleading and self-serving. The legislation is sloppy, ineffective and broadly worded. Expertise is denigrated. Lies are rewarded. And deep-seated, long-lasting national problems go permanently unresolved.

Moriarty escapes London, questioning everything he thought to be true. With Sherlock and Watson hot on his tail, he heads to the Continent with Moran to end the chaos once and for all.
