“There are endless worlds, your dinh is correct about that, but even when those worlds are close together—like some of the multiple New Yorks—there are endless spaces between. Think ya of the spaces between the inner and outer walls of a house. Places where it’s always dark. But just because a place is always dark doesn’t mean it’s empty. Does it, Susannah?”

There are monsters in the todash darkness.

Who had said that? Roland? She couldn’t remember for sure, and what did it matter? She thought she understood what Mia was saying, and if so, it was horrible.

“Rats in the walls, Susannah. Bats in the walls. All sorts of sucking, biting bugs in the walls.”

“Stop it, I get the picture.”

“That door beneath the castle—one of their mistakes, I have no doubt—goes to nowhere at all. Into the darkness between worlds. Todash-space. But not empty space.” Her voice lowered further. “That door is reserved for the Red King’s most bitter enemies. They’re thrown into a darkness where they may exist—blind, wandering, insane—for years. But in the end, something always finds them and devours them. Monsters beyond the ability of such minds as ours to bear thought of.”

Susannah found herself trying to picture such a door, and what waited behind it. She didn’t want to but couldn’t help it. Her mouth dried up.

In that same low and somehow horrible tone of confidentiality, Mia said, “There were many places where the old people tried to join magic and science together, but yon may be the only one left.” She nodded toward the Dogan. “It was there that Walter took me, to make me mortal and take me out of Prim’s way forever.

“To make me like you.”

Mia didn’t know everything, but so far as Susannah could make out, Walter/Flagg had offered the spirit later to be known as Mia the ultimate Faustian bargain. If she was willing to give up her nearly eternal but discorporate state and become a mortal woman, then she could become pregnant and bear a child. Walter was honest with her about how little she would actually be getting for all she’d be giving up. The baby wouldn’t grow as normal babies did—as Baby Michael had done before Mia’s unseen but worshipful eyes—and she might only have him for seven years, but oh what wonderful years they could be!

Beyond this, Walter had been tactfully silent, allowing Mia to form her own pictures: how she would nurse her baby and wash him, not neglecting the tender creases behind the knees and ears; how she would kiss him in the honeyspot between the unfledged wings of his shoulderblades; how she would walk with him, holding both of his hands in both of hers as he toddled; how she would read to him and point out Old Star and Old Mother in the sky and tell him the story of how Rustie Sam stole the widow’s best loaf of bread; how she would hug him to her and bathe his cheek with her grateful tears when he spoke his first word, which would, of course, be Mama.
