Flame in the Mist (Flame in the Mist #1)(73)

Then Mariko had recalled something Yoshi had taught her during one of her many lessons about mundane things. An excellent source of tinder was dried animal dung. He’d proven this when he’d taught her how to light a fire.

So she’d mixed equal parts dried horse dung with the yellow rocks and the pitch, grinding them all into a fine powder. The final addition of soot from Haruki’s smithy had stabilized the mixture and made it less noxious to work with.

The last task left to Mariko was to create a mold.

Thus the eggshells.

She needed something that would encase the powders in an almost crystalline structure. Make them easy to transport without falling apart or setting them off at the nearest brush of heat. Yesterday Mariko had remembered the Dragon’s Beard candy and how the sweet amazura syrup used to make it hardened when left too long away from the fire.

So she’d taken amazura syrup from Yoshi and let it melt over a low flame. She’d waited until it hardened before grinding it into a powder. Dusted it across the inside of the eggshell. Then left it near the heat once more to form a shell within the eggshell. A reinforcement that made the eggshells themselves far sturdier.

If this experiment didn’t work, she had to start from the beginning.

Mariko carefully measured out the three different powders in the three containers at her feet. She poured each into the eggshell lined with amazura glaze.

Then she stood.

As she’d learned early on when mixing these powders, friction caused them to react with one another and form a cloud of smoke.

She rattled the egg twice before throwing it hard on the ground.

It burst with a loud bang. A white smoke rose from the ground, smelling faintly of burnt eggs and horse dung. Tolerable, if one ran away quickly.

At least in one thing Mariko was not a complete failure.

—

“I’m impressed,” Ranmaru said when Mariko showed him the final product. His hand waved through the smoke so that he could see her.

Briefly Mariko considered what it meant that she was providing her enemy—her brother’s enemy—with the means to conceal himself from view. Alas, it was too late to hide her success, and—as far as she was concerned—the more smoke, the better. She’d begun working on this project before the events that had transpired in the clearing. When Mariko had wished to earn a place in the Black Clan’s inner circle. The only thing that saved her from feeling extreme guilt was the knowledge that she had not shared all she’d learned from her experiments.

She had no intentions of giving Ranmaru her greatest invention yet. Despite what her brother had done in Jukai forest, she would help Kenshin best his enemies in whatever way she could.

Mariko steeled herself.

The first chance she had, she would learn the reason Kenshin had murdered so many innocents. After everything she’d experienced while living amongst the Black Clan, she knew appearances could be deceiving. And she wished to give her brother the benefit of her trust, at least for the time being.

“How many smokeshields can you make?” Ranmaru asked.

Mariko hedged. “It’s time-consuming.”

“I’ll send men to help you. Ren and Yoshi will appreciate learning how to do this.”

And taking note of my ingredients, as well as seeing what else I am concocting.

“I prefer to work alone,” Mariko said. “It’s dangerous handling the powders, and an untried hand could set fire to the entire camp.”

Ranmaru remained unyielding. “Then train them to handle the powders properly.”

“I don’t have the time to train them and make the smokeshields.”

“Why don’t you tell me what you need, and I will provide it.”

The leader of the Black Clan’s unflinching nature was becoming increasingly problematic. Ranmaru rarely saw problems. He saw only solutions, and his eternal optimism grated on her nerves now more than ever.

Mariko thought quickly. Even if she disclosed the ingredients, none of the members of the Black Clan could ever duplicate the amounts. Not without weeks of study. And she would never tell them how she’d managed to harden the inside of the eggshell. “The yellow rocks near the hot springs. Dried horse dung. And ash from Haruki’s forge.”

“And foxglove.” A voice emanated from behind her.

ōkami.

“Foxglove?” Ranmaru said with a quizzical expression. “As in the poison?”

Mariko refrained from grimacing. “It’s true I have foxglove, but—”

ōkami stepped before her. “Don’t try to fool us, Lord Lackbeard,” he said in a flat tone. “If you didn’t use it for the smokeshields, then why did you need to gather it?”

Again she thought quickly. “I used foxglove sap to line the inside of the eggshells.”

Another lie, threaded from truth. Once again, Mariko recalled the experiment her tutor had performed when she was younger. When the paste from the foxglove stems and seeds had flashed a brilliant light. Mariko had realized early on that if she did in fact add the paste to the smokeshield, it would likely explode. Not just emit smoke and fumes.

Alas she’d not yet had an occasion to test her greatest invention yet.

“Interesting,” Ranmaru commented.

ōkami turned toward her, his face tense, as though he could smell the scent of her lies. “Quite.”
