Windmere Cove Cozy Mystery Book 4

Murder on the Indigo Sea

Murder on the Indigo Sea

"This is the first book I've read in the series. I enjoyed it so much that I've since purchased all the other books in the series. Very well written. I was reading before work, during my lunch and also in the evening. I couldn't figure out who did it, and couldn't wait to find out."
Dianna S.

"This book had me hooked from the very beginning. Even though it is Book 4, you did not need to read the prior books to enjoy this one. The character development was excellent, and the action took place very early in the book. The story line was so engrossing, I had a very difficult time putting the book down."
DH Thomas


A luxury vessel. Rare spices. An invitation most people would kill for. Someone did.

Aboard the Indigo Sea, the cargo is worth more than gold. So are its secrets. Izzy Harper had no business being there. She went anyway. Noodle in a bow tie. Evidence bags in her clutch. Three murders will do that to a person.

Captain Volkov is dead in the Grand Dignitary Meeting Room. The saffron in his teacup smells wrong. And the man fleeing the scene is someone Izzy trusted. Someone she was starting to feel something for. Someone who looked back at her once across a dead man and kept running. She followed.

Noodle, her golden retriever, is the only reason she turned back. He knows the difference between chasing answers and running from them.

Someone on this ship knows what really happened. Izzy just has to decide how much the truth is going to cost her.

Chapter 1: Murder on the Indigo Sea

Izzy Harper sat in her cottage behind Buttermilk Café, reviewing tomorrow's menu when Noodle lifted his head from his bed. His ears perked forward, tracking something she couldn't hear. A single knock echoed from her front door. She wasn't expecting anyone.

Noodle padded to the door, tail neutral, nose working.

Before she could call out, a white envelope slid under the gap, rain-spotted but intact. She picked it up. The whisk-and-pen emblem of La Société des Gourmets Discerning was pressed into red wax.

Inside, a single line in precise handwriting:

I have something of your grandmother's. Pier Seven. One hour. Come alone.

Her stomach tightened. La Société des Gourmets Discerning. The secret culinary society that had been at the center of three murders already. Spencer Reed, Malcolm Winters, Tony Mancuso. All connected to the bronze fragments, all dead.

Something of her grandmother's? What could they possibly have?

She'd been debating, pacing, second-guessing since the note arrived. Through the window, the sky looked threatening, heavy clouds gathering. Maybe that should have been her first warning this was a bad idea.

Noodle walked to the coat rack and sat, decision made.

"You're right," she said, pulling on her raincoat. "Better to go." She grabbed Noodle's yellow slicker from the hook. "Looks like rain, boy."

The note said come alone, but Noodle was already at the door, waiting patiently while she fastened his rain jacket.

They hurried to her Volvo just as the first fat raindrops began to fall. By the time she pulled into the harbor parking lot five minutes later, the storm had arrived in full force.

***

Wind howled through the rigging of moored boats, sending the Salty Dog and Morning Glory crashing against their bumpers. Rain hammered the docks in sheets so thick that even the lighthouse beam struggled to pierce through.

Pier Seven stretched into the harbor like a finger pointing toward the lighthouse. The pier lights struggled against the storm, their glow barely reaching the planks. Empty slips lined both sides, their usual occupants hauled out for winter storage. Rain pelted Izzy's face as she walked the length of the pier, seeing no one.

She checked her watch. Right on time.

"Hello?" Her voice disappeared into the storm.

Noodle pressed against her leg, alert but calm. Then she heard them. Footsteps on the wet planks behind her. Slow. Deliberate. Getting closer.

She turned.

A figure emerged from the shadows where the pier met the shore. Tall, wearing a long coat that somehow seemed to repel the rain. The pier light caught his face briefly. Middle-aged, sharp features, eyes that held too many secrets. She'd never seen him before.

"Miss Harper." His voice carried despite the storm.

Before she could respond, he grabbed her arm, firm but not painful, and steered her toward a small shelter she hadn't noticed. A covered bench area where fishermen waited out squalls. The wind still reached them, but the roof blocked the worst of the rain. Noodle followed, positioning himself between Izzy and the stranger.

"Thank you for coming," the man said, releasing her arm.

"Did I have a choice?"

"There's always a choice. Though not always a good one." He reached into his coat and pulled out a flat package wrapped in oilcloth, about the size of a recipe card.

"These were stolen from your grandmother's collection years ago," he said, extending the package. "The Society... acquired them. These belong to you. Soon, they'll make more sense.”

The oilcloth bore the whisk-and-pen symbol, beaded with rain. It was all Izzy could do not to tear it open right there, but the rain would damage whatever was inside. She tucked it carefully inside her coat.

"Why now?" she asked. "Why return them?"

The man studied her for a long moment. "Oh, Izzy. You don't understand yet, do you? The fragments you've been collecting? They're not the real Mechanism. They're the key to activating it."

The wind gusted, driving rain sideways across the pier. Noodle moved closer to Izzy, his warmth a comfort against the cold.

"The three fragments you've found," the man continued. "Each one powerful alone, yes. Cultivation, Fermentation, Catalyst. Remarkable devices in their own right. But when combined? They activate something that's been dormant. Something that could transform Windmere Cove."

"Transform it how?"

"That depends on who controls it. And that transformation? It will draw others. Dangerous others. People who've been waiting decades for this opportunity." Lightning flickered across the harbor, illuminating his face. "When you find the fourth fragment, the danger will escalate beyond anything you've faced. "The people you've dealt with before? Amateurs. What's coming..." He shook his head. "Study those recipes carefully. Your grandmother knew more than she ever told the Society."

"Wait," Izzy called as he turned to leave. "Who are you? Why warn me?"

He paused at the edge of the light. "The Mechanism should stay dormant. Not all Society members share that view." He studied her for a moment. "But if someone's going to figure this out, I'd rather it be you." He gestured to the package hidden in her coat. "The answers you need are in there. Though you may not recognize them at first."

Then he walked into the storm and was gone, swallowed by rain and darkness.

***

Back in her cottage, Izzy toweled Noodle dry while the package sat on her kitchen table, still wrapped in its protective oilcloth. The package pulled her back to her grandmother's kitchen, to the scent of cinnamon and brown sugar that always lingered there.

Finally, she couldn't wait any longer. She carefully unwrapped the leather sheath. Inside were four recipe cards, yellowed with age but perfectly preserved.

Her grandmother Margaret's handwriting flowed across the cardstock in faded blue ink:

Lonely Afternoon Cake

Forgiveness Pie

Second-Chance Bread

Sweet Regret Cookies

Each recipe included notes about emotions, stories, moods. Her grandmother's way of organizing recipes not by ingredient or course, but by feeling. Just like Izzy did now.

She picked up the Lonely Afternoon Cake card. The recipe called for brown sugar and sour cream, topped with cinnamon crumble. She had everything she needed.

"What do you think, Noodle? Midnight baking?" He wagged his tail and settled by the oven. “That’s what I thought. You just want the bowl.”

As she creamed butter and brown sugar, as cinnamon filled her kitchen, the scent pulled her back through time. She was eight years old, standing on a step stool in her grandmother's kitchen. September light streaming through windows. The house too quiet after Grandpa's funeral.

"Sometimes," her grandmother had said, folding cinnamon into butter with practiced hands, "we bake to fill the silence with sweeter things."

The cake had cooled on the windowsill while they waited, though neither knew quite what they were waiting for. Just that the waiting was easier with cake to share and stories to tell. Her grandmother had written it right there on the card: Best eaten warm, while waiting for company that may or may not arrive.

Even then, her grandmother had understood that some silences needed filling, some waiting needed purpose.

The memory faded as the timer dinged. Izzy pulled the cake from her own oven, the exact same smell filling her cottage. Lonely Afternoon Cake, perfect for a stormy night when questions outnumbered answers.

While the cake cooled, she studied the recipe cards more closely. That's when she noticed it. In the corner of each card, barely visible unless you looked at just the right angle, was a symbol: //

These weren't just recipes. They were something more. Instructions? A code?

Noodle suddenly nosed at the Forgiveness Pie card, flipping it over on the table. There, on the back, was different handwriting. Her breath caught.

Spencer Reed's precise script filled the back of the card:

This mark isn't decorative. Pattern repeats across all cards. Intentional, formulaic? Symbol or cipher? S.R.

Spencer had held these cards. Studied them. Before he died in her café, before he passed her the first fragment, he'd known about these recipes. Known about the // symbol.

The cake sat cooling on the counter, filling the cottage with warmth and memory. Outside, the storm was passing, thunder growing distant. But Izzy knew another kind of storm was building. The Society member's words echoed in her mind: "When you find the fourth fragment, the danger will escalate beyond anything you've faced."

She looked at the four recipe cards spread on her table, each marked with that mysterious // symbol. Somewhere in these recipes, in her grandmother's careful measurements and emotional notations, lay answers. Or perhaps more questions.

Noodle rested his head on her knee, and she stroked his ears absently.

"Spencer knew," she said quietly. "He knew about the symbol. About the recipes. He knew, and now he's dead."

The golden retriever's brown eyes met hers, steady and calm.

She picked up the Forgiveness Pie card again, studying Spencer's note.

But tonight, she had cake. She had Noodle. She had her grandmother's recipes returned after years of absence.

And she had a mystery that Spencer Reed had started investigating before his death. One hidden in her grandmother's careful handwriting and mysterious symbol.

The storm moved out to sea, leaving only the sound of rain dripping from the eaves.

She cut herself a slice of Lonely Afternoon Cake and sat at her kitchen table, surrounded by the echoes of recipes and secrets, while Noodle kept watch at her feet.

Whatever the // symbol meant, whatever her grandmother had hidden in these recipes, she would figure it out. She had to.

Because somewhere out there, the fourth fragment was waiting. And with it would come the dangerous others the Society member had warned about.
