Gabe had been trying to be discreet--for Valkyrie's sake, yes, but more pointedly, for Skulduggery's. The last thing the detective needed was more reason to let his control lapse. So Gabriel winced at Valkyrie's blunt assertion, torn between feeling relieved she didn't seem to be wondering how he'd known (or at least unbothered by it) and chagrined she hadn't stopped to think.

Gabe couldn't tell where, but maybe with time he'd figure it out. He tore his gaze from the sofa and turned back to Skulduggery. "Breathe," he said softly, his eyes on Skulduggery's. The way the detective's anger was taut with restrained action didn't bode well. "Why would China want to kill him?" He paused. "Why would her realisation of my true nature make her want to kill him so much that she would panic with the desire to?"
