The Ghosts of Blackwall's past

Blackwall hasn't always been a fire station; it started out in life as grounds for an abbey in 1446 and was demolished in 1887, before becoming a Fire Station in 1897, so naturally it would have plenty of ghosts to boast of. One in particular, the ghost of the most recently deceased Firefighter Roland Cartwright feels like it should make it's presence felt to the watch.
