Nightshift · slate pit 3

Gravelight

One lantern, one quarry face, and a seam that moves when you look away.

The lamp you carry reaches fifteen metres and no further. A working seam only answers when the beam is held within a few degrees of it, so you read the rock by walking the light across it. Loose gravel carries underfoot, and the foreman walks his round with a lamp of his own. Three sightings end the shift.

No shift worked yet tonight.
