They make it clear he's not wanted and life gets worse when he starts senior school and is bullied. When Davey is excluded for fighting his dad has the perfect excuse to pack him off to boarding school. But far from being a punishment, The Grey House is just about the best thing that ever happened to Davey. He makes new friends. His new history teacher, Mr. 'Spotty' Watty, takes a shine to Davey and reveals the school's secret; The Grey House is a refuge for ghosts stuck between this world and the next. Davey takes it upon himself to help the ghosts find eternal peace by going back in time with them to put right whatever it is that prevents their spirits from moving on.

His mission is to help his ghost friend - Midshipman Peter Wright - put right the injustice that torments his soul. What follows is a tale of ghosts, pirates, buried treasure and adventure.
