DI Alex Drake

 [ cont'd from here ]

She held tight to his hand as they swept through the door, the eerie light chasing them out into a gargantuan space.  The door clapped shut with a boom behind them. Beneath their feet, she felt rough stone floors and the air was humid and thick.  They weren't outside, because she could hear the echoes of the door ringing high above them.  There was an unidentified light source emanating from somewhere overhead.

"Well, this isn't Miliways."

Alex was still walking backwards when she turned to speak to Ichabod.  And it's a good thing he was close.  One foot kicked back into empty air and she almost fell over the edge of the cliff into pitch blackness.  She scrabbled for his arm, and caught herself before she overbalanced.

"Bloody hell..."

There was an ominous clicking sound.  And then there was a noise like boulders being slid across steel plates.  Beneath their feet, the floor began to shift.
