Skulduggery's gotten used to glimpses of dark hair in market crowds. There was a time when he could barely walk from one Sector to another without following up on any potential sightings - though to be fair, that time ended a while ago. Valkyrie was smart. If anything, she would find him.

So when he catches another glimpse this morning, he ignores it. Trick of the light. Wishful thinking. The usual list of excuses.

Only the glimpse doesn't vanish.

Skulduggery hesitates, then follows it, moving unnaturally smoothly through the crowd.
