Nothing but Shadows
There are two guest teachers this week, and—just Simon's luck—they're both Herondales. When Jace teaches a class at the Academy, warlock Tessa visits to share the true story of the Jack the Ripper murders.
The story opens with Simon and George talking to each other in the middle of the night. George correctly guesses that Simon is thinking about Isabelle, and they talk about their disgusting room. The next morning, Scarsbury tells the dregs class that they are going to climb up a tree, and that their guest teacher is none other than Jace Herondale. Simon is annoyed to find that all of the girls at the Academy are obsessed with Jace. Jace teaches the class how to drop, not fall, from a tree. Simon waits until the last possible moment to try the exercise, but, to his surprise, Jace turns out to be a good teacher. Still, Simon manages to embarrass himself by landing in a heap.
At lunch, Simon sits with Jace after being grossed out by the food. Jace tells Simon that he has been researching the Herondale family history, and he has realized that there were amazing people in his family, along with bad ones. Also, he informs Simon that Isabelle is upset about their fight at the warehouse in Brooklyn, and that Alec is, for some unknown reason, angry at Simon.
Later that day, Catarina introduces the guest lecturer to the class—Tessa Gray. She tells the class that she is half demon, half Shadowhunter, and that she lived among the Shadowhunters a hundred years before. Tessa thinks of herself as a living record of history, as she is the only person alive who knows the truth behind events that mundanes used myths to explain away. Tessa lived in London when the Jack the Ripper murders occurred, and she solved the mystery with the Shadowhunters of the London Institute.
The story moves to London in October 1888. Tessa admonishes Will for allowing James to carry a knife around the Institute, and she replaces it with a spoon instead. While Tessa reminisces about the early days at the Institute, Gabriel enters the room, clearly in distress. He is concerned about the Whitechapel murders, in particular the note that the killer left on the scene. Gabriel says that the timeline of the murders does not make sense because a human could not possibly accomplish multiple murders in that short of a time span, which leads him to believe that a demon is behind them. Also, he is rather disturbed by the fact that the killer took the childbearing organs out of the victims, all of whom were female prostitutes. Gabriel insists that they begin to patrol Whitechapel in search of the killer, in particular Tessa and Cecily, because the demon seems to be interested in women. Will agrees to the plan, on the condition that Jem accompany them. Although Gabriel clearly thinks this is a weird request, he agrees.
The story moves back to the present, and Tessa tells the class that there were no murders in the month of October, likely due to the Shadowhunters' patrol. Then, she dismisses the class for a break. Simon and George bump into Jace, and Simon tells Jace to ask Tessa about his family history. George is shocked that Jace treats Simon like his equal. Suddenly, Jon Cartwright comes over and says that he knows Jace on a personal level, which Simon knows not to be true. Then, Tessa begins to lecture the class again.
Tessa's story picks up on November 9, 1888. Tessa and Cecily disguised themselves as poor women on their patrols, and Tessa feels dirty whilst doing this. Also, the investigation is taking a mental toll on Tessa, as she and Will too tired to keep up with James and Lucie, and Gabriel and Cecily are too tired to keep up with Anna, their daughter. When Tessa and Cecily arrive at the tavern, Will says that the demon is likely an Eidolon, but they are getting nowhere in their investigation, so they go home. However, before Will and Tessa can get any rest, Gabriel arrives with news of another murder, the worst one yet. Tessa, Will, Gabriel, and Cecily go to the scene of the crime, and crowds have already gathered there. Tessa and Cecily go into the apartment where the prostitute was killed, and Tessa is horrified by all of the blood. Then, Tessa talks to the doctor who inspected the body, and he says that the body has been cut up, and the abdominal cavity emptied. Tessa goes back outside, and Gabriel surmises that the demon left the scene hours before.
When Will and Tessa return to the Institute, Tessa realizes that something is wrong. Her instincts are correct, as Bridget is found unconscious at the foot of the staircase and the children are missing. All of a sudden, they hear the voice of the demon, who says that s/he has the children, and s/he wants to play a hiding game with Tessa, Will, Gabriel, and Cecily. Jem arrives, and he senses that the children are alive and located somewhere in the house. Tessa realizes that the demon is likely a child, and it is looking for a mother figure. As Tessa voices this theory, Jessamine's ghost announces that she will play the hiding game with the demon. Jessamine convinces the demon to tell her where the children are so that they can come to her room to play with the dollhouse. After the adults locate the children, they arrive in Jessamine's room to find her with the demon. Jessamine tells the demon that they are going to play a fun game in which the demon needs to close its eyes. The demon, whose form is that of a young girl no more than five years old, obeys, and Will stabs her in the back with his seraph blade, killing it.
The story returns to the present day. Tessa tells the class that the demon was killed, but there was still work to do; the Shadowhunters had to convince the mundanes that there was an explanation for the murders other than a demon. There was much media attention focused on the killings, and since the murders stopped without finding the culprit, the mystery grew. The Shadowhunters considered staging a capture, but they were afraid that the mundanes would implicate them. However, such action was not needed, as the mundane media came up with so many theories that the truth was easily muddled. After Tessa finished her lecture, she embraced a man who was young and handsome, with black hair except for a single white streak. Simon realizes that the man is Jem Carstairs, formerly Brother Zachariah, and he thinks that his relationship with Tessa must be very complicated.
After Simon and George returned from dinner that night, they found Jace waiting in front of their room. Jace asks to speak to Simon alone, and Jace thanks Simon for telling him about Tessa; he found that she knew much of the Herondale family history, and he was happy to meet someone else with his blood. He told Clary, who apparently knew about Jace's relation to Tessa the whole time, but Tessa wanted Jace to come to her on his own. Jace says that he has never been happier; everything in his life is right, except for Simon not remembering him or the other New York Shadowhunters. Simon responds by telling Jace to wait outside while he does something in his room. Once he is inside, Simon goes about his usual routine before bed, until he decides to begin writing a letter to Isabelle. In the letter, Simon tells her that he is trying to figure out who he is, and that if she waits for him, he will make himself worth the wait, or at least try to do so. After writing the letter, he gives it to Jace to give to Isabelle. Jace tells Simon that he used to call him Wiggles before leaving. Although Simon knows this is untrue, and that Jace will call him that for the rest of his life, he remarks that it is "a small price to pay to get a letter to Isabelle."
Will stopped glaring at Gabriel, and turned to Tessa. He looked at her and his face softened: the traces of the wild broken boy he had been vanished, replaced with the expression often worn by the man he was now, who knew what it was to love and be loved. 'Dear heart,' he said. He took her hand and kissed it. 'Who knows your courage better than I?'
London, October 1888.
"It's not appropriate," Tessa said to her husband, Will.
"He likes it."
"Children like all sort of things, Will. They like sweets and fire and trying to stick their head up the chimney. Just because he likes the dagger..."
"Look how steadily he holds it."
Little James Herondale, age two, was in fact holding a dagger quite well. He stabbed it into a sofa cushion, sending out a burst of feathers.
"Ducks," he said, pointing at the feathers.
Tessa swiftly removed the dagger from his tiny hand and replaced it with a wooden spoon. James had recently become very attached to this wooden spoon and carried it with him everywhere, often refusing to go to sleep without it.
"Spoon," James said, tottering off across the parlor.
"Where did he find the dagger?" Tessa asked.
"It's possible I took him to the weapons room," Will said.
"It is, yes. It's possible."
"And it's possible he somehow got a dagger from where it is secured on the wall, out of his reach," Tessa said.
"We live in a world of possibilities," Will said.
