It was almost five miles from Highgate to the Institute; it had taken them three-quarters of an hour to cover the distance in the carriage. It took Will and Balios only twenty minutes to make the return trip, though the horse was panting and lathered with sweat by the time Will pounded through the Institute gates and drew up in front of the steps.
His heart sank immediately. The doors were open. Wide open, as if inviting in the night. It was strictly against Covenant Law to leave the doors of an Institute standing ajar. He had been correct; something was terribly wrong.
He slid from the horse’s back, boots clattering loudly against the cobblestones. He looked for a way to secure the animal, but as he’d cut its harness, there was none, and besides, Balios looked inclined to bite him. He shrugged and made for the steps.
Jessamine gasped and leaped back as Mortmain stepped into the room. Sophie screamed and ducked behind a pillar. Tessa was too shocked to move. The four automatons, two on either side of Mortmain, stared straight ahead with their shining faces like metal masks.
Behind Mortmain was Nate. A makeshift bandage, stained with blood, was tied around his head. The bottom of his shirt—Jem’s shirt—had a ragged strip torn from it. His baleful gaze fell on Jessamine.
“You stupid whore,” he snarled, and started forward.
“Nathaniel.” Mortmain’s voice cracked like a whip; Nate froze. “This is not an arena in which to enact your petty revenges. There is one more thing I need from you; you know what it is. Retrieve it for me.”
Nate hesitated. He was looking at Jessamine like a cat with its gaze fixed on a mouse.
“Nathaniel. To the weapons room. Now.”
Nate dragged his gaze from Jessie. For a moment he looked at Tessa, the rage in his expression softening into a sneer. Then he turned on his heel and stalked from the room; two of the clockwork creatures peeled themselves from Mortmain’s side and followed him.
The door closed behind him, and Mortmain smiled pleasantly. “The two of you,” he said, looking from Jessamine to Sophie, “get out.”
“No.” The voice was Sophie’s, small but stubborn, though to Tessa’s surprise, Jessamine showed no inclination to leave either. “Not without Tessa.”
Mortmain shrugged. “Very well.” He turned to the clockwork creatures. “The two girls,” he said. “The Shadowhunter and the servant. Kill them both.”
He snapped his fingers and the clockwork creatures sprang forward. They had the grotesque speed of skittering rats. Jessamine turned to run, but she had gone only a few steps when one of them seized her, lifting her off the ground. Sophie darted among the pillars like Snow White fleeing into the woods, but it did her little good. The second creature caught up to her swiftly and bore her to the ground as she screamed. In contrast Jessamine was utterly silent; the creature holding her had one metal hand clamped across her mouth and the other around her waist, fingers digging in cruelly. Her feet kicked uselessly in the air like the feet of a criminal dangling at the end of a hangman’s rope.
Tessa heard her own voice as it emerged from her throat as if it were a stranger’s. “Stop it. Please, please, stop it!”
Sophie had broken away from the creature holding her and was scrambling across the floor on her hands and knees. Reaching out, it caught her by the ankle and jerked her backward across the floor, her apron tearing as she sobbed.
“Please,” Tessa said again, fixing her eyes on Mortmain.
“You can stop it, Miss Gray,” he said. “Promise me you won’t try to run.” His eyes burned as he looked at her. “Then I’ll let them go.”
Jessamine’s eyes, visible above the metal arm clamping her mouth, pleaded with Tessa. The other creature was on its feet, holding Sophie, who dangled limply in its grip.
“I’ll stay,” Tessa said. “You have my word. Of course I will. Just let them go.”
There was a long pause. Then, “You heard her,” Mortmain said to his mechanical monsters. “Take the girls out of this room. Bring them downstairs. Don’t harm them.” He smiled then, a thin, crafty smile. “Leave Miss Gray alone with me.”
Even before he passed through the front doors, Will felt it—the jangling sense that something dreadful was happening here. The first time he’d ever felt this sensation, he’d been twelve years old, holding that blasted box—but he’d never imagined feeling it in the fastness of the Institute.
He saw Agatha’s body first, the moment he stepped over the threshold. She lay on her back, her glassy eyes staring up at the ceiling, the front of her plain gray dress soaked with blood. A wave of almost overwhelming rage washed over Will, leaving him light-headed. Biting his lip hard, he bent to close her eyes before he rose and looked around.
The signs of a melee were everywhere—torn scraps of metal, bent and broken gears, splashes of blood mixing with pools of oil. As Will moved toward the stairs, his foot came down on the shredded remains of Jessamine’s parasol. He gritted his teeth and moved on to the staircase.
And there, slumped across the lowest steps, lay Thomas, eyes closed, motionless in a widening pool of scarlet. A sword rested on the ground beside him, a little ways away from his hand; its edge was chipped and dented as if he had been using it to hack apart rocks. A great jagged piece of metal protruded from his chest. It looked a little like the torn blade of a saw, Will thought as he crouched down by Thomas’s side, or like a sharp bit of some larger metal contraption.
There was a dry burning in the back of Will’s throat. His mouth tasted of metal and rage. He rarely grieved during a battle; he saved his emotions for afterward—those he had not already learned to bury so deeply that he barely felt them at all. He had been burying them since he was twelve years old. His chest knotted with pain now, but his voice was steady when he spoke. “Hail and farewell, Thomas,” he said, reaching to close the other boy’s eyes. “Ave—”
A hand flew up and gripped his wrist. Will stared down, dumbfounded, as Thomas’s glassy eyes slid toward him, pale brown under the whitish film of death. “Not,” he said, with a clear effort to get the words out, “a Shadowhunter.”
“You defended the Institute,” Will said. “You did as well as any of us would have done.”
“No.” Thomas closed his eyes, as if exhausted. His chest rose, barely; his shirt was soaked almost black with blood. “You’d’ve fought ’em off, Master Will. You know you would.”
“Thomas,” Will whispered. He wanted to say, Be quiet, and you’ll be all right when the others get here. But Thomas manifestly would not be all right. He was human; no healing rune could help him. Will wished that Jem were here, instead of himself. Jem was the one you wanted with you when you were dying. Jem could make anyone feel that things were going to be all right, whereas Will privately suspected that there were few situations that his presence did not make worse.
“She’s alive,” Thomas said, not opening his eyes.
“What?” Will was caught off guard.
“The one you come back for. Her. Tessa. She’s with Sophie.” Thomas spoke as if it were a fact obvious to anyone that Will would have come back for Tessa’s sake. He coughed, and a great mass of blood poured out of his mouth and down his chin. He didn’t seem to notice. “Take care of Sophie, Will. Sophie is—”
