Sherlock Holmes needs a holiday, so Dr Watson has taken him to Dartmoor, where they find a very changed Baskerville Hall. The gaunt, gothic mansion has gone: it's now an eco-friendly, zero-waste yoga retreat. But trouble is (cold-)brewing beneath the solar panels. Someone is stirring up hate against the supposedly 'woke' agenda at Baskerville and is sending anonymous death threats, in the form of a gun's trigger and the word 'BEWARE'! Even worse, there are reports that the slathering hell-hound on the moor has returned! Can Holmes and Watson negotiate the heightened emotions between different social media tribes, without getting themselves permanently cancelled - or even murdered?
