It was not the whisky. The officer peered back where he'd come— pressing his face to the glass (helmet clicking at impact), just as Chang had done against the glare—before crossing to the metal door. Chang wondered he had not been seen, but knew that where one did not expect something one often neglected to look. The dragoon stuffed the flask back in his tunic, and came out with something else… a large metal key. He inserted it quickly into the black car's lock, standing casually so anyone who happened to see him might think he was merely smoking. Chang heard the snap of the bolts in the door… but instead of pushing it open, the officer merely sealed it shut again and then tucked the key back in his tunic.

The dragoon turned and saw him.

The soldier's hand shot to his saber hilt. Holding tightly to the ladder Chang kicked both legs at the Captain, one sharply to his chest and the other across his jaw, knocking him back into the metal door and then, with a dangerous stumble, into the rail of chain. Abandoning his attempt to draw his weapon, the man desperately caught hold with both hands to prevent toppling over. The kick left Chang hanging for a sickening moment by his hands, boots just above the implacably deadly wheels. He caught a leg on the lowest rung and tried another kick—but the Captain, his face red where Chang's boot had landed, snatched hold of Chang's ankle and yanked hard to pull him from the ladder to his death.

Chang held fast. The Captain pulled again, grunting aloud, boots slipping on the metal platform. Chang held, less certainly, and then, because he could not withstand a third pull, let go with one hand and stabbed his stick like a blunt court sword into the Captain's face. The officer flinched and swore aloud—blood welling under his eye. Dangling by one hand, Chang swung his other boot in a sweeping kick that caught the officer square on the ear, bouncing his brass helmet onto the trackside and the man again into the rail of loose chain, where he over-balanced and began to jackknife off the platform.

Before he could fall, Chang shot both legs forward and wrapped them tightly around the fellow's neck. The Captain leaned perilously forward, suspended over an abyss of rushing rail track, the chain caught uselessly below his waist, his open hands pawing the air. It seemed as if he must fall, but Chang held strong, looping both arms tight around the iron rungs, grimacing with the effort. Neither man moved, the train roaring around them. Then the officer carefully twisted his head to meet Chang's gaze. He said nothing, but his eyes burned with hatred and with fear.

“Whose key?” called Chang, loud enough for the man to hear above the wheels.

“Yours, if you want it,” sneered the Captain. “Of course, if you drop me—”

“I have one.” Chang dug his heel hard into the man's jugular. “Where did you get yours? Aspiche?”

“Leveret.”

“You searched Leveret's home. Does Aspiche know you have that key?”

The man spat. “If he knew, why would I be out here on my own?”

“What about the woman?”

“What about her? No one knows where she went!”

Chang's question had been about Mrs. Marchmoor, not Charlotte Trapping. But he nodded, playing along.

“Where do you think she went?”

“We can have this chat perfectly well on the damned platform,” the officer grunted. “I can feel your bloody legs slipping. We may well be of use to one another.”

“You're a liar.”

“My point exactly,” the Captain wheezed. “You have caught me out on forbidden business… the advantage is all yours…”

The man's point was echoed by a growing ache in Cardinal Chang's arms. With a grunt he heaved the Captain back toward the platform.

The man wavered, his fair hair blowing around his face, then caught the chain and dropped safely to his knees. By the time he looked up Chang had vaulted onto the shaking platform and pulled apart his stick, the dagger held ready at the level of the Captain's eyes. The officer looked past Chang at the compartment door.

“Not the best place for a private conversation,” he called.

Chang ignored this. “Why were you in that car at all? Why not in the back, with your betters?”

“Would you trust them—my betters?”

“If I were you—or your betters' master?”

The man shrugged, as if the question answered itself.

“What is your duty here?” asked Chang, impatiently.

“What was my duty in the north?” the Captain replied. “As one says in the Latin, ad hoc.”

The man's features were boyish, but his eyes were hard, as if too early disillusioned by the temptations available to his station.

“A great deal has changed in the city since we both left it,” said Chang.

The man shrugged again. Chang nodded at the key in the man's tunic.

“But I suppose change begets opportunity.”

“Have you seen their faces?” replied the Captain, with a wicked smile. “My God, by the smell alone—very soon there will be gaps in the upper echelons. And every gap needs filling.”

“You were telling me about the woman.”

The officer smiled, rubbing his throat. As he did, Chang noticed the man's face seemed more pale than it had in the woods, only days earlier. Fatigue? Or was he sick too, without knowing it?

“Mrs. Trapping has disappeared.”

“So has Leveret.”

“Leveret's a dull clot. He will be as obvious in his hiding place as a schoolboy crouching under a table.”

“Is Charlotte Trapping a clot?”

“Even more than Leveret! She is a society widow. She is marooned—she has no skills. The powerful brother has lost his mind, and the other brother… has vanished.”

“Along with the Contessa, and everyone else on the airship.”

“Quite a tragic journey, that,” said the Captain. “A comprehensive loss for the nation.”

Chang studied the man's face, as he knew the man studied his. The Captain had been in the train yard along with Chang—it was entirely possible he too had seen the Contessa and Xonck. In fact, he must have seen them—why else would the Ministries be searching Stropping with such vigor?

“As you say… there may be opportunities… Mrs. Trapping—” The Captain spoke carefully.

“What can a woman matter?” Chang interrupted. “Especially her?”

“The Privy Council believes Mrs. Trapping matters a great deal. Makes a fellow think…”

“Think what?” asked Chang, stepping closer.

The dragoon glanced at the knife blade and then up to Chang, girlish curls framing a mirthless smile. “That the Privy Council has lost its head.”

“Get out your key.”

CHANG TOSSED the dragoon's saber behind him on the chaise. He looked into the open coffin where the Captain lay, arms tucked tightly to his sides, face set with displeasure.

“What is your name?” asked Chang.

“Tackham. David Tackham.”

“They will find you when we arrive, if not before.”

“I assure you, it is not necessary—”

“It is this or cutting your throat,” said Chang.

“My point being, such a choice does not have to be—”

“What do you know of this Fochtmann?”

Tackham sighed. “Nothing at all. Engineer—invented some useful… thingummy.”

“And Rawsbarthe?”

“Another Foreign Ministry stick insect. Why the Duke entrusts such weak tea to do his bidding—”

“Where is Margaret Hooke?”

“Who?”

“Mrs. Marchmoor.”

“Who?”

“Where is Charlotte Trapping?”

“As I have told you—”

“Who is Elöise Dujong?”

“I've not the slightest idea—”

“Then where is Captain Smythe?”

Tackham was taken aback and smiled, unsure of the question's intent.

“I beg your pardon?”

“Captain Smythe,” snarled Chang. “Your brother officer.”

“Yes, of course—I just don't know why you would be asking, of all people!”

“Answer me.”
