Stepping back, Hildegarde pulled at her hair.
"Here," she said as she offered an old hairpin (hair falling untidily down one shoulder). "Not sure how this will assist you. Look. No key holes. This door must be sealed from within. In that case..."
Once she had handed the pin over, the Lord moved off to the surface for another look at the site. She had not seen the shed with the fuel supplies on this expedition, but she clung to the hope that it would still be there.
"If we cannot get in, perhaps we can slow down their fortifications - pull down the wooden barrier. Next time we come we must come in force. I think stealth is pointless now. And secure one of those guards... if they still live. We need to go back with... something."
Probably should have checked for this earlier, but is the fuel dump still on site? If it is, Hilde will move towards it in the hope of stealing a barrel of fuel and using it to bomb the door.
