“Speak,” said Kaz.

“It is my understanding that a certain ship, captained by a young Suli woman and flying under no country’s banner, has thrown the human trade in and out of Ketterdam into upheaval. I particularly liked the tale of the two slavers she left slathered in tar and crow feathers at the entrance to the Stadhall. I do admire her theatrics, though the Merchant Council was less impressed, perhaps due to the note pinned to the captain’s chest that read, ‘Gert Van Verent’s new mansion was paid for in bodies.’ It made for quite the story in the papers, and Mister Verent—a former member of the Council in good standing—is now under investigation.”

“He isn’t.”

“No?”

“He was found guilty and sentenced to two years in Hellgate. His political rivals have already carved up his fortune.”

“How swift is Kerch justice when there’s money to be made,” Nikolai marveled. “The captain and her ship are known only as the Wraith, but I have it on good authority that this mysterious Suli woman is Inej Ghafa.”

“Never heard of her.”

“No?” Nikolai feigned shock. “That surprises me, given her association with the Dregs and her considerable talent for puncturing people with all the zeal of a nearsighted auntie trying to embroider a quilt. But it may be for the best that you have no personal connection.”

“Is that so?”

They had stopped at a huge iron door with an elaborate locking mechanism.

“Have you heard of the izmars’ya?” Nikolai asked.

“My Ravkan is rusty.”

Even if that were true, Nikolai had no doubt Brekker knew exactly what the izmars’ya could do. But if he wanted to play, they would play.

“They’re submersible warships that travel beneath the sea. They can attack any vessel unseen, and are almost impossible to evade. Some very powerful people in Kerch possess this technology. If the Wraith’s enemies convince the Kerch government to use these weapons against her, the Wraith and her crew could be blown from the water at any time.”

“A dire situation for her, no doubt.” Kaz’s voice was even, but Nikolai saw the way his gloved hand gripped the silver crow’s head of his cane. “And perhaps for the person who invented such a menace.”

The threat was obvious.

“No doubt. But it so happens that when this technology was granted to the Kerch, the very wise king of Ravka—have you met him? Unusual for someone to be so smart and so good-looking—had the hulls of the izmars’ya imbued with bits of rhodium, so that with the help of a Fabrikator and a certain device in his keeping, a ship could receive early warning of any submersible within a three-mile radius and take evasive maneuvers. If said ship was so inclined.”

“An early warning system.”

“Precisely.”

Brekker reached for the handle of the door. “And you have this clever invention in your possession?”
