CASESO-012 / BELLHOUSE
CLASSIFICATIONACROSS — SEALED SITE
FAR SIDERegional Seat of Government 12, under Sheldon Moor, Derbyshire. The present day.
REGISTRY OFFICERMr Bewley

Bellhouse is a government bunker built into a worked-out coal mine under Sheldon Moor and commissioned in 1962. On 4 November 1974 its staff and their families, 412 people, went below for a civil defence exercise. The door was shut. Nobody came up.

In 1975 the entrance was filled in. After that the Seat is on no map, no index and no budget. Nobody asked why.

In May this year a Seat return dated Week 1, 1974, arrived in the Registry in-tray. It was not posted. It is enclosed (SO-H02). It is stamped with a small circle cut by a stroke. The same mark is on the letter of instruction recovered in case TT-004, Mercy Draw, 1881, from a Mr Smith whom the company never employed.

Coal smoke has been settling on Wetherlaw Farm, above the Seat, for fifty years. There is no chimney on the moor. The department’s reading is that the Seat is still occupied.

ORDERS

  1. The persons at the Seat are to be brought home. None is expendable.
  2. Force is authorised in self-defence only.
  3. Establish who delivered the Seat’s order in 1974 and who has instructed it since. Bring back his letters.
  4. The Seat is released under clause 4 of its Standing Order. Read clause 6 first.

CONDUCT

Anyone below has been there since 1974 and will believe what they were told. Be courteous. Carry your warrant card where it can be seen: a warrant of the Department is recognised at the Seat. Do not argue with anyone about the war.

Standing Order 9 applies. Nothing modern goes through.

ACCESS

A crossing stands at the warm vent head on Sheldon Moor, above Wetherlaw Farm. It opens at dusk. Mrs Joan Wetherlaw will meet you at the farm gate. She is not cleared.
