“I don’t think there’s anything under there.” Daniel sighed. He came out of his bedroom and shook his head sadly. “I haven’t noticed anything loose or creaking, and I think this is a dead end. And you have to be at the theater soon for the play.”

“Dammit.” She’d forgotten, and she dug her cell phone out of her pocket to check the time. “I have at least another ten minutes before I need to leave here. Let’s just keep looking.”

Marcy stood up. “Is there anyplace we haven’t looked?”

“I don’t know.” Daniel glanced around his living room.

“What about that?” Marcy asked. She’d started sucking on her finger, presumably in an attempt to remove the splinter, but she pointed to the fireplace with her free hand.

“What?” Gemma asked.

“In the fireplace.” Marcy took her finger out of her mouth so she’d be easier to understand. “That stone’s a different shade of gray.”

The whole fireplace was done up in large river rocks. Most of them were varying shades of light to medium gray, smoothed and polished to look nice. But one stone near the end of the mantel was a very dark gray with a bluish tone to it.

“Did you replace that stone or something?” Gemma asked Daniel, but she could already feel her heartbeat speeding up.

“No, I didn’t.” He shook his head and walked over to the fireplace, with Gemma right at his heels.

Slowly, almost gingerly, Daniel touched the stone. He started to wiggle it, and at first, nothing happened. Then he started pushing and pulling at it harder until it finally began to budge. As he started to slide the stone out, Gemma held her breath.

“Here.” He handed it to her, then he reached into the dark hole left in the fireplace and began to dig around. “I found something.”

“What is it?” Gemma asked.

“I don’t know. I think…” He let his sentence trail off as he pulled out a small, leather-bound book. “It’s a book.”

“Oh, my gosh.” Gemma nearly dropped the stone trying to take it from him, but Daniel caught the rock and set it on the ground. He stood behind her, peering over her shoulder as she flipped through it.

As soon as she saw the words, she knew. The small, delicate cursive matched the handwriting on the back of some of the pictures they’d gotten from Bernie’s house.

“‘On June 16, 1961, I married my one true love, Bernard McAllister,’” Gemma read aloud. “This is it, you guys. This is Thalia’s journal.”

“I told you I know everything,” Marcy said.

“Does it say anything else?” Daniel asked. “Like anything about sirens?”

“I don’t know.” Gemma flipped through the pages with trembling hands, scanning the faded ink on the yellowed pages. “It seems to be a lot of day-to-day stuff. Their garden. How much she loves Bernie.”

Then Gemma flipped to the back, and her heart sank.

The journal had been divided up into three sections—a calendar at the front, the journal pages in the middle, and a “notes” section in the back, for important information, like birthdays and addresses.

Writing covered the last section, written over the typed words, in the margins, sideways, to the ends of the pages and off them. Thalia had completely filled it … and all of it was written in symbols and shapes—a language that Gemma didn’t understand.

“Crap,” Gemma said. “It’s in Greek or something again.”

“Maybe it can help Lydia with the translation she’s working on,” Marcy suggested.

“We could bring it out to her tonight,” Gemma said. “See if she can make anything out of it.”

“You can’t,” Daniel said. He’d been reading over her shoulder, but he took a step back now.

“What? Why not?” Gemma asked.

“The Taming of the Shrew opens tonight. Remember?” he asked.

She waved him off. “No, I have an understudy or something. I need to stay and read this.”

“No, you need to go be in the play,” Daniel said.

“That’s insane.” Gemma shook her head. “This could be the piece we’ve been looking for.”

“You can’t even understand all of it,” Daniel said. “And if you skip the play, Thea and Penn will know something’s up, and that could be bad news. You don’t want them breathing down your neck while you’re trying to figure out this journal.”

Gemma sighed. “Good point.”

“Thank you,” Daniel said. “Now come on. I’ll take you guys back to the mainland.”

Gemma grumbled, but she did as she was told. On the boat ride back, she sat down in the sleeping quarters, safely away from the spray that might damage Thalia’s journal. She sat cross-legged on the bed and decided to read the parts she could decipher, and she started from the beginning.

In big letters in blotchy dark ink, Thalia had written an important inscription on the back of the front cover:

My dearest Bernard—if ANYTHING happens to me, you need to dispose of this. Nobody can ever find the secrets I’ve kept within these pages. It could be dangerous if in the wrong hands. For your safety, please destroy this.

Understudy

Behind the closed door emblazoned with a fallen starlet’s name, Gemma leaned in front of the mirror, applying thick eyeliner. Outside in the hall, she could hear people scrambling around to get ready for the first show, starting in twenty minutes.
