Will gave Magnus a withering look. "It does tend to be a permanent state. Here, give me my son."

Magnus let Will take James from his arms, which were left lighter if more damp, and Magnus followed Will's and Tessa's lead up the stairs. Inside the Institute it was clear they had been redecorating. Charlotte's dark drawing room now held several comfortable-looking sofas, and the walls were covered in light damask. Tall shelves were lined with books, volumes with the gilt rubbed off their spines and, Magnus was sure, the pages much thumbed. It appeared both Tessa and Will remained great readers.

Will deposited James onto one of the sofas. Tessa rushed to find a blanket as Magnus turned toward the door, only to find his hand caught in Will's grasp.

"It was very good of you to bring Jamie home," Will said. "But you were always so good to me and mine. I was little more than a boy then, and not as grateful or as gracious as I should have been."

"You were well enough, Will," said Magnus. "And I see you have grown to be better. Also, you are not bald, and neither have you grown fat. All that dashing about and fighting evil you people do is at least useful for keeping a trim figure in middle age."

Will laughed. "It's very good to see you, too." He hesitated. "About Jamie . . ."

Magnus tensed. He had not wanted to distress Will and Tessa too much. He had not told them that James had fallen when he was in the Serpentine, and made very little effort to rescue himself from drowning. He had not seemed to want to be taken from the cold depths of the water: had fought Magnus as he dragged him out, then laid his pale cheek against the dank earth of the riverbank and hid his face in his arms.

For a moment Magnus had thought he was crying, but as he stooped down to check on the boy, he found he was barely conscious. With his cruel golden eyes closed, he once again reminded Magnus of the lost boy Will had been. Magnus touched his damp hair gently and said "James," in as kind a voice as he could.

The boy's pale hands were splayed against the dark earth. The glimmer of the Herondale ring shone against his skin, and the edge of something metallic shone under his sleeve as well. His eyes were shut, the black lashes ink-dark crescents against the lines of his cheekbones. Sparkling drops of water were caught in the curling ends of those lashes, which made him look unhappy in a way he did not when awake.

"Grace," James had whispered in his sleep, and was silent.

Magnus had not been angry: he had found himself wishing for a benevolent grace many times himself. He bent and gathered the boy up in his arms. His head lolled against Magnus' shoulder. In sleep James had looked peaceful and innocent, and wholly human.

"This just isn't like him," Will was saying now as Tessa drew a blanket up over the boy, tucking him in firmly.

Magnus raised an eyebrow. "He's your son."

"What are you trying to imply?" Will demanded, and for a moment Magnus saw his eyes flash, and saw the boy with messy black hair and glaring blue eyes standing in his drawing room, furious at the whole world and at no part of it more than himself.

"It isn't like him," Tessa agreed. "He's always been so quiet, so studious. Lucie was the impetuous one, but they are both kind, good-hearted children. At parties Jamie could most often be found curled up in a corner with his Latin, or laughing at a private joke with his parabatai. He always kept Matthew out of trouble as well as himself. He was the only one who could make that indolent boy attend to his studies," she remarked, with a slight smile that betokened she was fond of her son's parabatai, no matter what his faults. "Now he is out at all hours, doing the most disgraceful things, and he will not listen to reason. He will not listen to anybody. I understand what you mean about Will, but Will was lonely and wretched in the days when he behaved badly. James has been wrapped in love all his life."

"Betrayed!" Will muttered. "Cruelly maligned by my friend and now by my own cherished wife, scorned, my name blackened-"

"I see you are still fond of histrionics, Will," said Magnus. "As well as still handsome."

They had grown up. Neither of them looked startled at all. Tessa raised her eyebrows, and Magnus saw something of her son in her then. They both had the same expressive, arched brows, giving their faces a look of both inquiry and amusement, though in James's face the amusement was bitter.

"Do stop flirting with my husband," said Tessa.

"I shall not," Magnus declared, "but I will pause briefly so that I may catch up on your news. I have not heard from you since you sent word the baby had arrived and both he and his lovely mother were thriving."

Will looked surprised. "But we sent you several letters in care of the Morgensterns, who were going to visit the Whitelaws at the New York Institute. It was you who proved to be a shocking correspondent."

"Ah," said Magnus. He himself was not even slightly surprised. This was typical behavior from Shadowhunters. "The Morgensterns must have forgotten to deliver them. How careless."

Tessa, he saw, did not look too surprised either. She was both warlock and Shadowhunter, and yet not quite either. The Shadowhunters believed that Shadowhunter blood trumped all else, but Magnus could well believe that many of the Nephilim might be unkind to a woman who could do magic and whom the years did not touch.

He doubted any of them dared be unkind in front of Will, though.

"We will be more careful about whom we entrust with our letters in future," Tessa said decisively. "We have been out of touch for far too long. How fortunate that you are here in London, both for us and for Jamie. What brings you here, business or pleasure?"

"I wish it were the business of pleasure," Magnus told her. "But no, it is very dull. A Shadowhunter I believe you know sent for me-Tatiana Blackthorn? The lady used to be a Lightwood, did she not?" Magnus turned to Will. "And your sister Cecily married her brother. Gilbert. Gaston. I have a shocking memory for Lightwoods."

"I begged Cecily not to throw herself away on a Lightworm," Will muttered.

"Will!" said Tessa. "Cecily and Gabriel are very happy together."

Will threw himself dramatically into an armchair, touching his son's wrist as he passed by, with a light, careful caress that spoke volumes.

"At least you must admit, Tess, that Tatiana is as mad as a mouse trapped in a teapot. She refuses to speak to any of us, and that includes her brothers, because she says we had a hand in her father's death. Actually, she says we pitilessly slew him. Everybody tries to point out that at the time of the pitiless slaying her father was a giant worm who had eaten her husband and followed up his meal with a palate-cleansing servant sorbet, but she insists on lurking about the manor house and sulking with all the curtains drawn."

"She has lost a great deal. She lost her child," Tessa said. She stroked back her son's hair, her face troubled. Will looked to James and fell silent.

"Mrs. Blackthorn has come from Idris to her family manor in England specifically so I might visit her, and she sent me a message through the usual Downworlder channels promising me a princely sum if I would come and cast a few spells to increase the attractions of her young ward," Magnus said, attempting to strike a lighter note. "I gather she wishes to marry her off."

Tatiana would not be the first Shadowhunter to seek a warlock's spells to make her life easier and more pleasant. She was, however, the Shadowhunter offering the best price.
