Shadow should have been suspicious of the woman from the Library, and indeed, retained a certain level of paranoia out of habit. However, when she consulted her intuition, it told her that Mercy was sound, and the presence of the ka, Perra, was further testament to this. Ka spirits did not take well to evil, sent from the gods as they were. As ancestral guides, they were evidence of a degree of divine faith. Besides, she thought that Mercy would have concocted a less bald narrative, had she been lying.
She checked anyway, leaving Mercy alone in the lab. The Librarian on duty said placidly that Mercy Fane was currently on sick leave, but would be back soon.
Therefore, Shadow had little reservation about taking Mercy to meet Mariam Shenudah. The latter would, she felt, have her own opinions on what had transpired, and if she did not trust Mercy, she would have little hesitation in saying so. And doing something about it.
They had sealed the severed hand in its box. Shadow had no intention of letting it out of the laboratory, but she had taken pictures. Interesting to see what Shenudah would make of it.
They reached Mariam’s apartment close to twilight. Mercy would not, she had told Shadow, be obliged to return to work immediately: she could call in sick, and muttered something about preferring her to do so-something about an inspection. Shadow had not offered to put her up overnight, but had asked Sephardi to find her a room in a nearby guest house. The Librarian had not seemed to take affront at this.
Shenudah lived at the summit of an apartment block, one of the many that had gone up around the Medina in recent years. It was rickety, covered in bamboo scaffolding and tangles of plants where enterprising dwellers had made the most of their balconies, given the lack of a garden. Mercy followed her up flights of winding stairs.
“She says it keeps her fit,” Shadow said over her shoulder.
“I’m not surprised.”
The building creaked and groaned like a ship in a high wind. Shadow was almost relieved when they reached the final flight and an ancient door, incongruous in the modern setting of the apartment block. Shadow knocked, once. “Mariam? It’s me.”
A pause, then the door opened and a small face looked out. Shenudah, like her door, was elderly, but as usual she was dressed with the utmost smartness: a neat black suit with a rose and lily corsage, sheer stockings, high-heeled shoes.
“Good evening!” The voice was brisk and educated.
“Mariam, I’ve brought a visitor. From the Library.”
Shadow was conscious of a piercing stare over her shoulder, then the old woman said, “You look like someone I used to know, once.”
“Who was that, Mrs-er,”
“It’s Dr Shenudah. But you may call me Mariam. Come in.”
On her first visit here, Shadow had expected a motley, shambolic apartment filled with books, but Mariam Shenudah’s home was tidy and controlled. All four walls were covered in bookcases, but these were neatly filed and the books were in alphabetical order, in a range of languages from Arabic to Mandarin. A polished wooden table stood in the centre of the room, bearing a vase filled with roses and the curving statue of an ibis. Shadow looked with pleasure at the familiar deep, rich colours: gold and dun and deep red, rose pink and ivory, the colours of a desert at twilight.
“Sit, please,” Mariam Shenudah said. “I will bring tea.”
“I hadn’t forgotten that the Eastern Quarter runs on tea,” Mercy said, with a smile.
“The West, too,” Shadow murmured.
“Or booze. But I don’t suppose you drink alcohol, do you?”
“No. I am observant. But I don’t object to others doing as they see fit. We all have different paths, after all.”
Once Mariam had brought the round silver tray of tea glasses, she once more looked at Mercy. “Allow me to guess. Your mother is called Greya Fane. She had a partner called Sho.”
“You knew them?”
“Yes, well. Perhaps forty years ago, now. A long time. How old are you, Mercy?”
“I’m twenty-eight.”
“I knew Greya in the north, when she lived in Aachven. She was a child of the Wolf Clans, as doubtless you know.”
“Yes. They’re my family, but I’ve never met them. Sho and Greya… kept themselves to themselves. I’ve never been sure what had gone wrong.” She paused. “I’ll be honest with you. I don’t know who my father was. Greya chose him because she and Sho wanted to have a child, but I don’t know anything about him.”
How odd Westerners could be, Shadow thought. But that wasn’t quite fair: Sho had come from this quarter, evidently.
Mariam said, “Greya was always-reckless. She took risks-magical ones. She associated with people whom a wiser, older woman would not have gone near, but Greya was young, and I’m afraid she was easily beguiled by glamour. I’m sure you are more sensible, Mercy.”
“I always thought of her as cautious,” Mercy said. “Annoyingly so, actually. But then she bolted into the blue on the Barquess, so… ”
“Maybe she’d learned from experience, at least until the Skein departed. But when I knew her, she courted risks like another woman might court lovers. There was a forest lodge, a cult dating back to ancient times. Blood magic and sigil magic. Greya became involved. I am telling you this not because of any interest in your family history, but because it relates to your current situation. Sephardi has spoken to me, about the thing you have both seen. I know what that thing is.”
“What is it?” Mercy and Shadow both spoke at the same time.
“Disir.”
Shadow saw that Mercy was frowning. “I know that word. I’ve heard it before, but I don’t know what it means. Is that thing a ‘disir,’ then? What are they?”
“They are the children of Loki, the lord of misrule and more than misrule. Their story says that they were born out of the drops of poison and blood that the god shed when he was chained, springing from the earth and the ice. Their name means ‘the ladies’ and they are essentially ancestral spirits, but some stories are not meant to last. They have curdled and turned foul, like sour milk.”
“And now one of them has escaped from an ancient text.”
“They have bred with men although the Wolf Clans would not touch them, and there are rumours that their descendents are active in Worldsoul. They reap chaos, they are dukes of blood.”
“We need a magic to stop it,” Shadow said. “We can’t have it running around attacking people. There are practical considerations here, regardless of its history.”
“I understand,” Mariam said placidly. She took a sip of tea. “There is a spell to bind them, but it is not easy. It’s blood magic, as I have said, and requires a commitment.”
Involuntarily, Shadow and Mercy glanced at one another. “Whose blood?” Mercy said.
“That would be yours. You released it, Shadow injured it. You both have a connection to it and thus, it is your blood which must be given, but given freely.”
“As long as it’s only a drop,” Mercy said, after a long pause. She did not seem keen; Shadow could not blame her. There was something in her expression which Shadow could not interpret.
“The same for me,” Shadow said.
“Then I will show you the spell,” Mariam told them.
Mercy and Shadow stood side by side that midnight, in the middle of Shadow’s laboratory. Shadow had put the veil aside. Out of respect, Mercy had glanced at her face only once, even though she had seen it before. The alchemist had the fierce profile of a falcon, a curving nose, high-angled cheeks.
She had asked the ka, privately, if the alchemist could be trusted. Perra had said that in its opinion, the answer was yes, but Mercy was still unhappy about the blood ritual. Maybe it wasn’t just Greya who was a risk-taker… the thought that she might be treading in her mother’s footsteps was a dismaying one.
The ka stood watch as Shadow once again inscribed a circle in fire and placed a silver bowl filled with water and roses before them. They spoke the spell together, Mercy trying not to stumble over the unfamiliar words, and then Shadow took the sun-and-moon blade and nicked first her own palm, then Mercy’s. The drops of blood fell, mingled, into the bowl and the roses went up in a hiss of flame.
“… and I abjure you now, in the name of Solomon the King and the Book of Solomon which holds all the names of God… ”
Shadow’s voice, quiet and firm, spoke through the sudden roar of fire. This was the old magic of Asia Minor, winding its way through Europe in the Renaissance and perhaps before, a magic of fire and bare rock and burning sky. Here, on the rim of the Great Desert, it seemed appropriate, Shadow’s voice whispering out of the ages and conjuring ancient names. Mercy looked down into the bowl and saw that the roses were gone; the bowl was bubbling with blood. Her sigilometer was ticking like a metronome, registering magic. Across the room, in the triangle, the writhing mottled form was once again appearing, but this time it was solid.
“Hold!” Shadow’s voice rang out across the room. Mercy could see the disir clearly now, the rows of teats down her abdomen between the cracked leather harness, the razor-toothed mouth.
“Hold!” The blood, far more than the few drops that Mercy and Shadow had shed, boiled over the lip of the bowl and surged towards the edge of the circle, then beyond, a thin line of red reaching out to the triangle and extinguishing the fire. The disir sprang out, crouching for a moment, then rushing forward. Shadow’s blade was already out and Mercy freed the sword, stepped back, and came up against a wall of air. The circle was still holding her in; if she tried to strike, she was likely to hit Shadow. The alchemist cried out and struck down with the blade. But the disir had learned from the loss of her hand. Mercy could see the stump, wrinkled and seamed, looking like an old injury. The disir moved with unnatural speed, up the wall and across the ceiling like a spider. Shadow uttered an imprecation and cast a Name upwards: it missed the disir by inches and scorched itself into the ceiling to flare for a moment before flaking out into ash.
“Take the circle down!” Mercy yelled. Shadow did so, and she was free to move. She vaulted across the work table, sending an alembic crashing to the floor in a shower of glass and landing in a defensive sprawl as the disir dropped from the ceiling. As Mercy had already briefly grappled with it, she was almost prepared for the blast of cold that the disir brought in its wake. The disir raked out with long claws, but the lost hand was hampering it. Mercy, on her feet again, dodged back, slashing out with the Irish blade and severing the disir’s harness. A streak of welling black blood appeared in the sword’s wake and the disir hissed in pain. The blood spattered across the floor. The disir rushed at Mercy, who ran backwards and slipped on the pool of the mingled blood that had seeped from the bowl. She fell and the disir was on her, but there was a sudden blast of light and heat and the intense cold was blown back by warmth. The smell of roses was all around, sandalwood, myrrh, filling the laboratory in an intoxicating wave of perfume. Mercy gasped, scrambling to her feet. The disir was backing away. She heard Shadow say something, urgently, and turned to look at her, but the light was too bright, too blinding. Mercy threw an arm across her eyes but as she did so, she glimpsed the diminished spidery shape of the disir clambering up the wall to the high arched window. There was a shatter of breaking glass and the disir was gone, scrambling down the city wall.
Light, and a presence that filled the laboratory. Shadow was speaking, but Mercy did not understand the language. Something laughed and it was not human. Then it, too, was gone, leaving heat and the scent of roses in its wake.
“Shadow?” Mercy’s vision was still blurred.
The alchemist was huddled on the floor. “Are you hurt?”
“No.” Shadow looked up and Mercy realised the alchemist was consumed with fury. “That was-well. Someone who has no business in my business.”
“Who are you talking about?”
“Suleiman the Shah. That was one of his spirits, his djinn. He saved my life-and yours. That means he’s bound me to him, when that has been the very thing that I’ve been trying to avoid.”
