Alec took a deep breath and let it out. Well, he’d come this far; he might as well go on. The bare lightbulb hanging overhead cast sweeping shadows as he reached forward and pressed the buzzer. A moment later a voice echoed through the stairwell. “WHO CALLS UPON THE HIGH WARLOCK?” “Er,” Alec said. “It’s me. I mean, Alec. Alec Lightwood.” There was a sort of silence, as if even the hallway itself were surprised. Then a ping, and the second door opened, letting him out onto the stairwell. He headed up the rickety stairs into the darkness, which smelled like pizza and dust. The second floor landing was bright, the door at the far end open. Magnus Bane was leaning in the entryway.
