Secret headquarters
There is a big unmarked grey warehouse type thing (king of thing where you’d expect to find a large Comet, Homebase and the like) by the side of the track just outside Norwhich on the Sherringham line. It’s got large black double gates to get in and out, black double fence surrounding with barbed wire and two loading bays that are always closed. Nothing seems to be parked outside it ever and the only people you ever see are security patrolling the perimeter. Sounds very secret basey to me
