Vera's home office was a masterclass in minimalism. There were no scattered papers, no personal photographs. Just a sleek glass desk, an ergonomic black leather chair, and the soft, cool glow of a high-end laptop monitor.
It was 2:28 AM. Detective Lais would likely begin his neighbourhood inquiries by sunrise. Vera had precisely four hours to ensure he found nothing but a pristine, upper-class suburban mirage.
She cracked her knuckles—a rare, unrefined habit she only allowed herself in absolute solitude—and began typing.
Her target was the local Homeowners Association's cloud server. The neighbourhood was riddled with video and audio-recording doorbells, driveway sensors, and high-definition security cameras. To the average resident, it was a safety bubble where crime didn't exist. To Vera, it was an unacceptable liability. Fortunately, the HOA president used his dog's name and birth year as a master password, mixed with a few random words relating to his hobbies. It was offensively easy to bypass. On the one hand, Vera appreciated his time-saving predictability; on the other, she felt insulted. Her disdain grew exponentially.
Vera accessed the archive for Premium Point in Westchester, filtering the timeframe to two days prior to her art intervention.
The screen flickered, splitting into four quadrants: a high-definition feed from the camera mounted on the building directly across from her aunt's house, a view of Brown's driveway, another of the entrance gate, and finally, a feed from Hannah and Max's house midway down the street.
There it was. The lemonade stand.
Vera leaned back in her chair, a faint smile touching her lips as she watched the silent film of her own curation unfold on the screen.
The video showed Lena and Lea standing behind a wooden picnic table, a bright yellow pitcher resting between them. At exactly 5:45 PM, a black SUV pulled into the driveway next door. Arthur Brown stepped out, looking characteristically flushed and furious, shouting into his Bluetooth earpiece.
On the screen, Vera watched her digital self exit her own front door, holding a pair of gardening shears. She had timed it flawlessly.
The mechanism of a perfect murder isn't violence, Vera thought, her eyes tracking her own graceful movements on the monitor. It is simply the right substance introduced at the right moment.
The toxin she had used was a masterpiece of her own making. A highly purified, weaponised strain of Clostridium botulinum, carefully synthesised in the sterile environment of her private lab. Unlike the vulgar street poisons that caused convulsions or vomiting, her formula was a gentleman's weapon. It was odourless, colourless, and completely undetectable to the human palate, especially when masked by the sharp acidity of lemons and sugar. Once ingested, it bound irreversibly to the nerve endings, blocking the release of acetylcholine. The result was a quiet, descending flaccid paralysis. The lungs simply forgot how to pull in air, while the heart forgot how to beat.
On the screen, Arthur Brown barked something at the twins. The girls shrank back. He was likely complaining about their stand blocking a fraction of his pristine walkway, or perhaps shouting that he didn't have time for them.
Vera recalled her own words, delivered on screen with perfectly feigned sweetness: "Oh, come on, Arthur. They've been standing here since this morning trying to raise some money for a good cause. They're doing no harm."
Digital Vera approached the table, offering a polite, neighbourly smile that didn't quite reach her eyes. She placed a five-dollar bill in the girls' jar and asked for two cups of lemonade—one for her, one for Arthur, as a gesture of "peace".
Vera paused the video, zooming in on her own hands.
To the naked eye, it looked as though she was simply handing the plastic cup to the angry hedge fund manager. But in that frozen frame, Vera knew exactly what was happening. Tucked beneath her index finger, hidden by the curve of the cup, was a microscopic, water-soluble capsule. As her thumb brushed the rim to hand him the drink, the capsule dropped silently into the iced yellow liquid.
It dissolved in less than one second.
Arthur took the cup, apologised to his little neighbours, gave Vera a dismissive nod, and chugged half of it in one gulp before turning his back and marching into his house. He had swallowed his own aesthetic end.
Vera unpaused the video, watching Arthur's front door close. That was the penultimate time the neighbourhood saw him alive. The following morning, he left for work and never returned.
"A flawless performance," Vera whispered to the empty room, laughing under her breath.
She highlighted the entire block of footage from 5:00 PM to 7:00 PM. With a few rapid keystrokes, she didn't just delete it; she replaced it with a seamless, edited loop of Lena and Lea standing at their lemonade stand from the previous day. The shadows of the trees matched perfectly. So did the routines of all the neighbours.
She did the same for all the cameras that might have caught a glimpse of Arthur's trajectory and the poisoned transaction.
By 3:15 AM, the digital footprint of her crime was completely eradicated. However, she had one last thing to do.
She had to check Brown's commute to ensure nothing odd had occurred at work that could be traced back to her.
Vera accessed the archive for Madison Avenue, filtering the timestamps for the next morning between 7:00 and 9:00 AM, when Arthur arrived at work.
The screen flickered again, loading a high-definition feed from the camera mounted on the building directly across from her target's office, monitoring his window and entrance door.
She didn't need to alter anything on this digital archive; she just needed intel.
Vera followed her subject as he entered his workplace. Nothing out of the ordinary, except for a slight falter in Brown's step during his final entrance. Nothing to worry about.
She then double-checked his commute. Nothing other than him driving angrily, likely shouting at some unfortunate employee over the phone.
Perfect. Detective Lais could watch all the footage he wanted. He would only find Lena and Lea handing one glass after another to virtually all the neighbours, followed by a regular 9-to-5 workday.
Vera closed the laptop, satisfied, plunging the room back into darkness.
Her intel groundwork was complete. The physical evidence—the capsule—was dissolved. The delivery system—the lemonade—was digested. The digital memory was wiped clean. It was highly unlikely the twins would accurately remember her brief interaction with Arthur, and even if they did, their young age rendered them unreliable witnesses. Besides, they had sold a lot of lemonade over those three days.
The neighbourhood remembered nothing but a sunny afternoon.
She stood up, walked to her pristine kitchen, and poured herself a glass of chilled sparkling water.
Let Detective Lais come. Vera was ready to play the perfect, lovely, and kind neighbour.
