Alek stiffly returned her salute. “Mr. Tesla, I believe you’ve met Middy Sharp?”
“He was kind enough to drop in on me in Siberia,” the inventor said. “Are those feathers?”
Deryn looked down at herself. Trapped in the engine grime on her flight suit were, indeed, a few feathers.
Deryn flicked one off and snapped her heels, as if she were at a formal dance instead of in an engine room covered with bilge. “I was tending to the strafing hawks. Very kind of you to visit, Mr. Tesla.”
Tesla waved his walking stick. “I’m not visiting; I’m here to help. This engine is based on my design, you know.”
“What exactly happened here?” Alek asked.
“The propellers sucked in a bit of rocket,” Deryn said, avoiding Alek’s eyes. “Started a fire, so the engineers called for a Herculean inundation. Watch your step, please.”
Inside, the engine pod smelled like the gut of the ship. The floor was covered in gunk, the machinery blackened by fire. The engineers stopped their work and stared at Mr. Tesla, their eyes wide.
“A Herculean inundation?” the inventor asked. “As in the seven labors?”
Deryn looked puzzled, so Alek jumped in. “They must have flushed the rear ballast through the pod. Hence that sudden dive that sent us all sliding across the bridge.”
Tesla lifted one shoe to peer at its grimy sole. “Both ingenious and unhygienic, like so much Darwinist technology.”
Deryn stiffened a bit, but her voice stayed level. “You say you invented this particular engine, sir?”
“I created the principles of alternating current.” Tesla poked at the machine with his walking stick. “Much safer on an airship.”
Alek nodded. Visiting the pods a few days ago, he’d noticed how the electrikal engines didn’t spit smoke or sparks, and ran almost silently.
“Alternating current,” Bovril repeated happily.
“But you don’t have a boiler room aboard,” Tesla said. “Where does the power come from?”
“These fuel cells here.” Deryn looked down at a pile of small metal kegs. “Hydrogen made by wee beasties in the whale’s gut.”
“A biological battery!” Mr. Tesla exclaimed. “But they can’t have much power.”
“They don’t have to, sir.” Deryn gestured out the pod’s high windows. “Darwinist airships get most of their push from cilia—those wee hairs along the flanks. The engines just give it a nudge in the right direction, and the airbeast does the rest.”
“But the
“Excellent.” Mr. Tesla pulled off his jacket. “Well, let’s get to work, then. The more engines the better!”
As Mr. Tesla worked, he held forth on a variety of topics—from world peace to his fascination with the number three—but Alek found it all a bit hard to follow. Master Klopp had never taught him much about electrikal engines, which weren’t powerful enough to use in walkers.
At first Alek tried to help by handing Tesla his tools, but the engineers soon crowded him out for the honor. Just like Bovril, they hung on the great man’s words. Alek found himself reduced to a waste of hydrogen, as usual.
Then he noticed that Deryn had stepped out onto the stabilizing boom. Of course, Alek had been avoiding her the last few days. But it was childish, pretending not to know each other. Their sudden falling out might start Dr. Barlow asking questions, and the last thing Alek wanted was for Deryn to be found out thanks to him.
He took a deep breath and stepped out through the hatchway.
“Hello, Dylan.”
“Afternoon, your princeliness.” Deryn didn’t look up. She was staring down at the passing ocean, the wind barely ruffling her muck-matted hair.
For a moment Alek wondered if she were upset about him seeing her like this, covered in grime. But that was nonsense. Ordinary girls worried about that sort of thing, not Deryn.
“Mr. Tesla should get your engine working soon,” he said.
“Aye, he’s a barking genius. You should hear the engineers go on about it.” She looked aft. “And it seems he’s got the captain’s head spinning too.”
“What do you mean?”
Deryn pointed at the glare of sunlight in the airship’s wake. “We’re headed due east. We’ll be in Tokyo tomorrow.”
“Of course,” Alek said. “Now that we’ve lent the Japanese navy a hand, we can depart with Britain’s honor intact.”
“The lady boffin said the same thing, but I thought she was blethering!”
“Dr. Barlow doesn’t blether. Your Admiralty couldn’t let Tsingtao fall without British aid, because the Japanese aren’t properly…” He spread his hands, looking for the right word. “European. It wouldn’t do for them to beat the Germans without our help.”
For the first time Deryn looked straight at him. “You mean we came halfway round the world just for show? That’s the biggest load of yackum I’ve ever heard!”
“Yackum,” Bovril said, and leapt down onto the handrail.
Alek shrugged. “More or less. But there was a higher purpose, it seems. Now we can help Mr. Tesla stop the war.”
Deryn gave him the same exasperated look she did whenever he mentioned his destiny.
“Are you going to punch me again?” Alek asked. “Because I’d like to get a good grip. It’s a long fall.”
A smirk flashed across her face, but her eyes didn’t soften.
“You are rather strong,” Alek said.
“Aye, and I’m taller than you too.”
Alek rolled his eyes. “Listen, Deryn—”
“It’s not a good habit, you calling me that.”
“Perhaps not. But I’ve been calling you the wrong name for so long, I feel I should make up for it.”
“It’s not your fault I’ve got two names.”
Alek looked down at the water slipping past. “So whose fault is it? I mean, even Volger thinks you’re a fine soldier, and yet you have to hide who you are.”
“It’s just the way things are.” She shrugged. “It’s no one’s fault.”
“Or everyone’s,” Alek said. “Deryn.”
“Deryn Sharp,” said Bovril quietly.
Both of them stared at the perspicacious loris in horror.
“Brilliant,” Deryn said. “Just barking
“I’m sorry.” Alek shook his head. “I didn’t realize—”
Suddenly her hand was across his mouth. He smelled engine grease and brine on her palm, then saw the message lizard making its way along the underbelly of the ship. Deryn let her hand fall, gesturing for silence.
The lizard spoke with Dr. Barlow’s voice. “Mr. Sharp, tomorrow afternoon you shall accompany me to Mr. Tesla’s meeting with the ambassador. I seem to recall, however, that you have no formal uniform. We shall have to remedy that when we arrive in Tokyo.”
Deryn swore, and Alek recalled that her only dress uniform had been destroyed in the battle of the
“Um, but—but, ma’am,” Deryn sputtered. “I’ll have to—”
“Dr. Barlow,” Alek broke in, “this is Prince Aleksandar. I know you want young Dylan to look his best, but gentlemen’s tailoring is hardly your area of expertise. It would be my pleasure to go with him. End message.”
