Chapter 3 - The Secret in the Leaves

Night fell over the city in a torrent of cold November rain. Nia rode the subway home, sitting in a dimly lit train car that smelled of wet wool and ozone. She kept her right hand clamped tightly inside her coat pocket, her fingers wrapped around the small plastic bag containing the stolen tea leaves.
Every shadow on the platform felt like an enforcer sent by Carlo. Every sudden movement made her flinch. She knew she was operating on borrowed time. Carlo was paranoid; the way he had looked at her in the master suite proved that his suspicions were aroused. If he noticed the tea level in the canister was slightly altered, or if he simply decided a nosey maid was too much of a liability, she wouldn't make it past tomorrow's morning shift.
When she reached her small, run-down apartment on the north side of the city, she double-locked the heavy deadbolt and shoved a chair under the door handle.
She turned on the single overhead lamp in her cramped kitchen.
Nia pulled the plastic bag from her coat and emptied the contents onto a clean sheet of white paper.
The blend was mostly yellow, fibrous chunks of dried ginger root, mixed with green tea leaves and dried honey granules. But scattered throughout were tiny, brittle pieces of dark, grayish-green leaves with tiny, microscopic white hairs on their underside.
Nia grabbed a magnifying glass and a pair of tweezers from her late grandmother’s wooden sewing kit—the kit she had brought with her when she moved away from Oregon after her mother passed away.
She carefully separated the dark leaf fragments from the tea and ginger.
Under the magnifying glass, the leaf structures were definitive. The vein patterns were irregular, netting outward from a thick central ridge, covered in subtle downy fuzz.
It was Digitalis purpurea. Common foxglove.
Nia sat back in her wooden kitchen chair, her hands trembling.
"He's giving him a lethal dose every single day," she whispered aloud to the quiet room.
A raw leaf dose of foxglove was notoriously difficult to measure, which explained why Matteo hadn't died instantly. Carlo wasn't trying to drop him overnight—that would raise immediate suspicions of poisoning. Instead, he was slow-dosing him, allowing the toxic cardiac glycosides to build up in Matteo’s heart tissue day after day, slowly paralyzing the sodium-potassium pumps in his cells, driving his heart rate down to fatal levels while giving him terrible visual disturbances and gastrointestinal agony.
The doctors weren't seeing it because digitalis toxicity mirrored severe end-stage heart failure and systemic organ decay. Without a specific digoxin assay ordered, the automated lab machines simply didn't report it.
Nia locked her hands behind her head, staring at the ceiling.
She had the truth. But how could she use it?
If she walked up to Enzo tomorrow morning and said, "Hey, the maid knows your boss is being poisoned with foxglove," Enzo would either shoot her on the spot as a lunatic, assume she was part of the plot, or Carlo would cut her throat before she finished the sentence.
Enzo was a loyal guard dog, but he was impulsive and violent. If she approached him without flawless execution, Carlo would simply deny it, accuse her of trespassing or planting evidence, and have her eliminated.
She needed to test the tea in a real lab, or she needed to force the medical team to run the exact test right in front of Enzo.
Her phone chimed on the table.
It was a text notification from the Costa Estate automated staffing portal:
ALERT: Housekeeping Shift Reassignment. Employee #4092 (Lewis, N.) - Your scheduled shift for Friday, Nov 14th on the 3rd Floor Master Suite has been CANCELLED. Report to Basement Laundry Facility at 06:00 AM.
Nia stared at the glowing screen.
Carlo was already moving. He was cutting off her access to the third floor. He was pushing her down to the basement where she couldn't see, hear, or touch anything.
Once she was isolated in the basement, it would be child's play for one of Carlo's men to stage an "accident"—a slip on a wet concrete floor, a fall down the elevator shaft, or a simple disappearance into the night.
Nia stood up, her fear suddenly hardening into a cold, sharp resolve.
"No," she said softly to the dark apartment. "I'm not dying in a basement."
Her grandmother had taught her two things: how to recognize the plants that heal and kill, and how to survive when you are surrounded by wild animals.
If Carlo wanted to play a silent game of chess, Nia was going to flip the entire board.
She grabbed a pen and a small piece of paper. She wrote down three words in precise, clear block letters:
DIGOXIN TOXICITY. TEST THE TEA.
May you like
She folded the paper into a tight, narrow square.
Tomorrow morning, she wasn't going to the basement. She was going back to the third floor, and she was going to ignite a fire that neither Carlo nor Enzo could put out.
