Inside, it is more of a long crack than a spacious cavern. The entry way can't be more than 10ft wide, and the cave veers off at an oblique angle from there. The main part of the chamber begins about 10ft in and is not quite 20ft wide nor 30ft deep. Beyond this space the fissure narrows for a further 20ft before the cave ends.
The main part of the cave is occupied by the ogre cook-fire and ring of stools; it must have been a bit tight for four of the brutes!
However, it doesn't take a moment for Desmond to spot their secret. A heavy rock on the left hand cave wall--beyond the fireplace--is plainly out of kilter; it must have been pulled across to conceal another tunnel!
What now?
