I heard the heavy thud of boots running past my hiding spot.

“She’s not on the train!” one of them yelled.

“Search the platforms,” another voice replied, closer this time.

My phone vibrated in my pocket again.

The screen lit up, casting a faint blue glow on the damp brick wall.

It was a call from an unknown number.

I hesitated, then pressed the phone to my ear, keeping my voice to a bare whisper.

“Clara,” a gruff voice said on the other end.

“Who is this?” I asked, my heart pounding.

“It’s Jack Vance,” the voice said. “Your mother told me this day would come.”

“They’re chasing me,” I whispered. “I’m in the tunnels under State Street.”

“Listen to me carefully,” Vance said. “You need to get out of the city.”

“I have the babies,” I said. “Dominic’s twins.”

There was a long pause on the line.

“You have both of them?” Vance asked, his voice suddenly grave.

“Yes,” I said. “Why?”

“Leo won’t stop until they are dead,” Vance said. “You don’t understand what those children represent.”

“What do they represent?” I asked.
