"Careful," Gabriel warned, holding out a hand and swiping through one of the sleeping-spell sigils with his chalk. The spell fizzled and died with Skul only a few inches from penetrating it. "It's not a complicated spell; I'm sure you had someone with the same skill."

Besides, he wouldn't have been able to fight in any war. Not in the capacity Skul was imagining.

The shift of the mountain made Gabriel tense and look just as Skulduggery did. He looked at the detective and bit his lip. "Actually, that was in the opposite direction to the wards I laid. That ... isn't a good sign. We probably shouldn't wait. Let's get away from here--just around the corner would be far enough. I'll look for your name there."

He nodded down the offshoot tunnel, fixed the sleeping spell to catch anyone else tried to go past, and left the glamour up. Just in case.
