For many years, it appeared to have meant nothing. Both James and Lucie could bear Marks and seemed to have the abilities of any other Shadowhunter. They could both see ghosts—like the Institute’s chatty phantom-in-residence, Jessamine—but that was not uncommon in the Herondale family. It seemed they might both be blessedly normal, or at least as normal as a Shadowhunter could be. Even the Clave—the governing body of all Shadowhunters—had seemed to forget about them.

Then, when James was thirteen, he first traveled into the shadow realm. One moment he had been standing on green grass: the next, charred earth. A similarly scorched sky arced above him. Twisted trees emerged from the ground, ragged claws grasping at the air. He had seen such places in woodcuts in old books. He knew what he was looking at: a demon world. A Hell dimension.

Moments later he had been jerked back to earth, but his life had never been the same again. For years the fear had been there that he might at any moment hurtle back into shadow. It was as if an invisible rope connected him to a world of demons, and at any moment the rope could be pulled taut, snatching him out of his familiar environment and into a place of fire and ash.

For the last few years, with his uncle Jem’s help, he’d thought he had it under control. Though it had been only a few seconds, tonight had shaken him, and he was relieved when the Devil Tavern appeared before them.

The Devil made its home at No. 2 Fleet Street, next to a respectable-looking print shop. Unlike the shop, it was glamoured so that no mundanes could see it or hear the raucous noises of debauchery that poured from the windows and the open doors. It was half-timbered in the Tudor style, the old wood ratty and splintering, kept from falling down by warlocks’ spells. Behind the bar, werewolf owner Ernie pulled pints: the crowd was a mix of pixies and vampires and lycanthropes and warlocks.

The usual welcome for Shadowhunters in a place like this would have been a cold one, but the patrons of the Devil Tavern were used to the boys. They greeted James, Christopher, Matthew, and Thomas with yells of welcome and mockery. James stayed in the pub to collect drinks from Polly, the barmaid, while the others tramped upstairs to their rooms, shedding ichor on the steps as they went.

Polly was a werewolf, and had taken the boys under her wing when James had first rented out the attic rooms three years ago, wanting a private bolt-hole he and his friends could retreat to where their parents wouldn’t be hovering. She was the one who’d first taken to calling them the Merry Thieves, after Robin Hood and his men. James suspected he was Robin of Locksley and Matthew was Will Scarlett. Thomas was definitely Little John.
