…As they made their way back towards the entrance, Harding’s mind was a whirlwind of questions. Croft’s involvement, Mary’s secret dealings, the identity of Spectre, the true motive behind her disappearance.

The truth, Harding knew, was still buried deep beneath the unseen sky, and it was far more dangerous than he could have ever imagined.
