“Do you mean how is it possible that we finally tracked down the last demon in London and it was also the most disgusting?” James was surprised by how normal his voice sounded: he was already shaking off the shock of his glimpse into the shadow realm. At least his clothes were untouched: the demon seemed to have exploded mostly over the other end of the alley. “Ours is not to question why, Christopher.”

James had a feeling his friends were gazing at him resentfully. Thomas rolled his eyes. He was scrubbing at himself with a handkerchief that was also half-burnt and covered in ichor, so it was doing little good.

Matthew’s seraph blade had begun to sputter. Seraph blades, infused with the energy of angels, were often a Shadowhunter’s most trusted weapon and best defense against demons, but it was still possible to drown one in enough ichor. “This is an outrage,” Matthew said, tossing the extinguished blade aside. “Do you know how much I spent on this waistcoat?”

“No one told you to go out patrolling for demons dressed like an extra from The Importance of Being Earnest,” said James, tossing him a clean handkerchief. As he did, he felt his hand sting. There was a bloody cut across his palm from the blade of the knife. He closed his hand into a fist to prevent his companions from seeing it.

“I don’t think he’s dressed like an extra,” said Thomas, who had turned his attention to cleaning off Christopher.

“Thank you,” said Matthew with a slight bow.

“I think he’s dressed like a main character.” Thomas grinned. He had one of the kindest faces James had ever known, and gentle hazel eyes. None of which meant he didn’t enjoy mocking his friends.

Matthew mopped at his dull gold hair with James’s handkerchief. “This is the first time in a year that we’ve patrolled and actually found a demon, so I’d supposed that my waistcoat would probably survive the evening. It’s not as if any of you are wearing gear either.”

It was true that Shadowhunters usually hunted in gear, a sort of flexible armor made of a tough, leatherlike black material resistant to ichor, blades, and the like, but a lack of reliable demonic presence on the streets had made them all a bit lax about rules.

“Stop scrubbing at me, Thomas,” said Christopher, windmilling his arms. “We should go back to the Devil and clean up there.”

There was a murmur of assent among the group. As they picked their sticky way back to the main street, James considered the fact that Matthew was right. James’s father, Will, had often told him about the patrols he used to do with his parabatai, Jem Carstairs—now James’s uncle Jem—back when they had battled demons nearly every night.
