Every night from 7pm Marple is effectively closed to the outside world. The authorities have imposed a curfew on our community and have blockaded the one road in and out. There are rumours of emergency vehicles on stand-by. Flashing lights and strange signs have appeared. There are concerns that the government is engaged in an experiment in mind control, to manipulate the patience of a whole town in readiness for the imposition of a police state.
Obviously this is just me being fanciful. The only true statement in the above paragraph is that the main road, Dan Bank, is closed at night for a while. The council have set up an exceptionally good public information service and website.
There's also a terrific blog, here, about the tunnels under Marple and the existence of a bunker. Here are the tunnels on a map. Fascinating stuff.
