Magnus gave him a consoling smile. "Cheer up," he said. "You can find far more flattering headgear at any shop in Bond Street."

The man fainted. Magnus considered pausing to help him, but there was being a soft touch, and then there was being ridiculous enough to not pursue a most enticing mystery. A Shadowhunter who could turn into a shadow? Magnus turned and bolted after the bobbing policeman's helmet, held aloft only by a taunting darkness.

They ran down street after street, Magnus and the darkness, until the Thames barred their path. Magnus heard the sound of its rushing swiftness rather than saw it, the dark waters at one with the night.

What he did see was white fingers suddenly clenched on the brim of the policeman's helmet, the turn of James Herondale's head, darkness replaced with the tilt of his slowly appearing grin. Magnus saw a shadow coalescing once more into flesh.

So the boy had inherited something from his mother as well as his father, then. Tessa's father had been a fallen angel, one of the kings of demons. The boy's lambent golden eyes seemed to Magnus like his own eyes suddenly, a token of infernal blood.

James saw Magnus looking, and winked before he hurled the helmet up into the air. It flew for a moment like a strange bird, spinning gently around in the air, then hit the water. The darkness was disrupted by a silver splash.

"A Shadowhunter who knows magic tricks," Magnus observed. "How novel."

A Shadowhunter who attacked the mundanes it was his mandate to protect-how delighted the Clave would be by that.

"We are but dust and shadows, as the saying goes," said James. "Of course, the saying does not add, 'Some of us also turn into shadows occasionally, when the mood takes us.' I suppose nobody predicted that I would come to pass. It's true that I have been told I am somewhat unpredictable."

"May I ask who bet you that you could steal a policeman's helmet, and why?"

"Foolish question. Never ask about the last bet, Bane," James advised him, and reached casually to his belt, where his gun was slung, and then he drew it in one fluid, easy motion. "You should be worrying about the next one."

"There isn't any chance," Magnus asked, without much hope, "that you are rather a nice fellow who believes he is cursed and must make himself seem unlovable to spare those around him from a terrible fate? Because I have heard that happens sometimes."

James seemed amused by the question. He smiled, and as he smiled, his waving black locks blended with the night, and the glow of his skin and his eyes grew as distant as the light of the stars until they became so pale, they diffused. He was nothing but a shadow among shadows again. He was an infuriating Cheshire cat of a boy, nothing left of him but the impression of his smile.

"My father was cursed," James said from the darkness. "Whereas I? I'm damned."

The London Institute was exactly as Magnus remembered it, tall and white and imposing, its tower cutting a white line against the dark sky. Shadowhunter Institutes were built as monuments to withstand the ravages of demons and time. When the doors opened, Magnus beheld again the massive stone entryway and the two flights of stairs.

A woman with wildly curling red hair, whom Magnus was sure he should remember but didn't, answered the door, her face creased with sleep and crossness. "What d'you want, warlock?" she demanded.

Magnus shifted the burden in his arms. The boy was tall, and Magnus had had a long night besides. Annoyance made his tone rather sharp as he answered:

"I want you to go tell Will Herondale that I have brought his whelp home."

The woman's eyes widened. She gave an impressed sort of whistle and vanished abruptly. A handful of moments later Magnus saw a white figure come softly down one of the staircases.

Tessa was like the Institute: hardly changed at all. She had the same smooth youthful face that she had worn twenty-five years before. Magnus thought she must have stopped aging no more than three or four years after he had last seen her. Her hair was in a long brown plait, hanging over one shoulder, and she was holding a witchlight in one hand and had a small sphere of light shining in her palm in the other.

"Been taking magic lessons, have we, Tessa?" Magnus asked.

"Magnus!" Tessa exclaimed, and her grave face lit with a welcoming smile that sent a pang of sweetness through Magnus. "But they said- Oh, no. Oh, where did you find Jamie?"

She reached the bottom of the steps, went over to Magnus, and cradled the boy's damp head in her hand in an almost absentminded gesture of affection. In that gesture Magnus saw how she had changed, saw the ingrained habit of motherhood, love for someone she had created and whom she cherished.

No other warlock would ever have a child of their own blood. Only Tessa could have that experience.

Magnus turned his head away from Tessa at the sound of a new footfall on the stairs.

The memory of Will the boy was so fresh that it was something of a shock to see Will himself now, older, broader of shoulder, but still with the same tousled black hair and laughing blue eyes. He looked just as handsome as he had ever been-more so perhaps, since he seemed so much happier. Magnus saw more marks of laughter than of time on his face, and found himself smiling. It was true what Will had said, he realized. They were friends.

Recognition crossed Will's face, and with it pleasure, but almost instantly he saw the burden Magnus carried, and worry erased all else.

"Magnus," he said. "What on earth happened to James?"

"What happened?" Magnus asked musingly. "Well, let me see. He stole a bicycle and rode it, not using his hands at any point, through Trafalgar Square. He attempted to climb Nelson's Column and fight with Nelson. Then I lost him for a brief period of time, and by the time I caught up with him, he had wandered into Hyde Park, waded into the Serpentine, spread his arms wide, and was shouting, 'Ducks, embrace me as your king!'"

"Dear God," said Will. "He must have been vilely drunk. Tessa, I can bear it no longer. He is taking awful risks with his life and rejecting all the principles I hold most dear. If he continues making an exhibition of himself throughout London, he will be called to Idris and kept there away from the mundanes. Does he not realize that?"

Magnus shrugged. "He also made inappropriate amorous advances to a startled grandmotherly sort selling flowers, an Irish wolfhound, an innocent hat stand in a dwelling he broke into, and myself. I will add that I do not believe his admiration of my person, dazzling though I am, to be sincere. He told me I was a beautiful, sparkling lady. Then he abruptly collapsed, naturally in the path of an oncoming train from Dover, and I decided it was well past time to take him home and place him in the bosom of his family. If you had rather I put him in an orphanage, I fully understand."

Will was shaking his head, shadows in his blue eyes now. "Bridget," he shouted, and Magnus thought, Oh, yes, that was the maid's name. "Call for the Silent Brothers," Will finished.

"You mean call for Jem," Tessa said, dropping her voice, and she and Will shared a look-what Magnus could describe only as a married look, the look of two people who understood each other completely and yet found each other adorable all the same.

It was quite sickening.

Chapter Four

He cleared his throat. "Still a Silent Brother, then, is he?"
