Tessa spun back around. Jem was clutching his cane, breathing hard. Blood ran down the side of his face from a cut, but he seemed otherwise unharmed. He held his weapon loosely in one hand as he gazed at a dark humped shape on the ground at his feet, a shape that moved and jerked, flashes of metal showing between the ribbons of its torn clothing. When Tessa moved closer she saw that it was the body of the coachman, writhing and jerking. His head had been sliced cleanly away, and a dark oily substance pumped from the stump of his neck, staining the ground.
Jem reached up to push his sweat-dampened hair back, smearing the blood across his cheek. His hand shook. Hesitantly Tessa touched his arm. “Are you all right?”
His smile was faint. “I should be asking you that.” He shuddered slightly. “Those mechanical things, they unnerve me. They—” He broke off, staring past her.
At the south end of the bridge, moving toward them with sharp staccato motions, were at least a half dozen more of the clockwork creatures. Despite the jerkiness of their movements, they were approaching swiftly, almost hurtling forward. They were already a third of the way across the bridge.
With a sharp click the blade vanished back into Jem’s cane. He seized Tessa’s hand, his voice breathless. “Run.”
They ran, Tessa clutching his hand, glancing behind only once, in terror. The creatures had made it to the center of the bridge and were moving toward them, gathering speed. They were male, Tessa saw, dressed in the same kind of dark woolen coats and felt hats as the coachman had been. Their faces gleamed in the moonlight.
Jem and Tessa reached the steps at the end of the bridge, and Jem kept a tight grip on Tessa’s hand as they hurtled down the stairs. Her boots slipped on the damp stone, and he caught her, his cane clattering awkwardly against her back; she felt his chest rise and fall against hers, hard, as if he were gasping. But he couldn’t be out of breath, could he? He was a Shadowhunter. The Codex said they could run for miles. Jem pulled away, and she saw that his face was tight, as if he were in pain. She wanted to ask him if he’d been hurt, but there was no time. They could hear clattering footsteps on the stairs above them. Without a word Jem took hold of her wrist again and pulled her after him.
They passed the Embankment, lit by the glow of its dolphin lamps, before Jem turned aside and plunged between two buildings into a narrow alley. The alley sloped up, away from the river. The air between the buildings was dank and close, the cobblestones slick with filth. Washing flapped like ghosts from windows overhead. Tessa’s feet were screaming in their fashionable boots, her heart slamming against her chest, but there was no slowing down. She could hear the creatures behind them, hear the whir-click of their movements, closer and closer.
The alley opened out into a wide street, and there, rising up before them, was the looming edifice of the Institute. They dashed through the entrance, Jem releasing her as he whirled to slam and lock the gates behind them. The creatures reached them just as the bolts slid home; they crashed against the gate like windup toys unable to stop themselves, rattling the iron with a tremendous crash.
Tessa backed up, staring. The clockwork creatures were pressed up against the gates, their hands reaching through the gaps in the iron. She looked around wildly. Jem stood beside her. He was as white as paper, one hand pressed to his side. She reached for his hand, but he stepped back, out of her reach. “Tessa.” His voice was uneven. “Get into the Institute. You need to get inside.”
“Are you hurt? Jem, are you injured?”
“No.” His voice was muffled.
A rattle from the gate made Tessa look up. One of the clockwork men had his hand through a gap in the gate and was pulling at the iron chain that held it closed. As she stared in fascinated horror, she saw that he was dragging at the loops of metal with such force that the skin was peeling away from his fingers, showing the jointed metal hands beneath. There was obviously tremendous strength in those hands. The metal was warping and twisting in his grip; it was clearly a matter of minutes before the chain split and broke.
Tessa seized hold of Jem’s arm. His skin was burning hot to the touch; she could feel it through his clothes. “Come on.”
With a groan he let her pull him toward the front door of the church; he was staggering, and leaning on her heavily, his breath rattling in his chest. They lurched up the stairs, Jem sliding out of her grip almost the moment they reached the top step. He hit the ground on his knees, choking coughs ripping through him, his whole body spasming.
The gate burst open. The clockwork creatures spilled through into the drive, led by the one who had torn the chain apart, his skin-stripped hands gleaming in the moonlight.
Remembering what Will had said, that one had to have Shadowhunter blood to open the door, Tessa reached for the bellpull that hung beside it and yanked it, hard, but heard no sound. Desperate, she whirled back to Jem, still crouched on the ground. “Jem! Jem, please, you have to open the door—”
He raised his head. His eyes were open, but there was no color to them. They were all white, like marbles. She could see the moon reflected in them.
“Jem!”
He tried to rise to his feet, but his knees gave out; he slumped to the ground, blood running from the corners of his mouth. The cane had rolled from his hand, almost to Tessa’s feet.
The creatures had reached the foot of the steps; they began to surge upward, lurching a little, the one with the skinned hands in the lead. Tessa flung herself against the doors of the Institute, pounding her fists against the oak. She could hear the hollow reverberations of her blows echoing on the other side, and despaired. The Institute was so huge, and there was no time.
At last she gave up. Turning away from the door, she was horrified to see that the leader of the creatures had reached Jem; it was bending over him, its skinned metal hands on his chest.
With a cry she seized up Jem’s cane and brandished it. “Get away from him!” she cried.
The creature straightened up, and in the moonlight, for the first time, she saw its face clearly. It was smooth, almost featureless, only indentations where the eyes and mouth should have been, and no nose. It raised its skinned hands; they were stained dark with Jem’s blood. Jem himself lay very still, his shirt torn, blood pooling blackly around him. As Tessa stared in horror, the clockwork man wiggled his bloody fingers at her, in a sort of grotesque parody of a wave—then turned and sprang away down the steps, almost scuttling, like a spider. He dashed through the gates and was lost to view.
Tessa moved toward Jem, but the other automatons moved swiftly to block her way. They were all as blank-faced as their leader, a matching set of faceless warriors, as if there had not quite been time to finish them.
With a whir-click a pair of metal hands reached for her, and she swung the cane, almost blindly. It connected with the side of a clockwork man’s head. She felt the impact of wood against metal ringing up her arm, and he staggered to the side, but only for a moment. His head whipped back around with incredible speed. She swung again, the cane slamming against his shoulder this time; he lurched, but other hands flashed out, seizing the cane, yanking it from her grasp with such force that the skin of her hand burned. She remembered the painful strength of Miranda’s grip on her, as the automaton who had snatched the cane from her brought it down across his knee with stunning force.
