The Ares Protocol

The rain didn’t fall on the 80th-floor penthouse; it attacked. Sheets of water, driven by a wind that howled like a banshee, hammered against the floor-to-ceiling windows of Arthur Vance’s sterile kingdom.

Inside, it was silent, save for the faint, expensive hum of the air filtration system.

Detective Miles Kincaid hated it. He hated the height, the silence, and the smell—a sterile fusion of ozone and lemon-scented cleaner. He preferred the city’s honest stink: wet asphalt, exhaust, and stale coffee.

“He’s in the study, Kincaid,” Detective Harding grunted, not bothering to look up from his notepad. Harding was a uniformed cop who’d made detective by ticking boxes, and he despised private investigators. “But you’re wasting your time. This one’s a ghost.”

Kincaid ignored him, pulling his trench coat tighter. The coat was damp, and it dripped onto the flawless white marble. “Hired by the widow?”

“Yeah. Elara Vance. She’s in the lounge. Says she wants ‘the best,’ and apparently, that’s you.” Harding’s lip curled. “Funny, she called you before she called us.”

Kincaid raised an eyebrow but said nothing. He pushed open the heavy oak door to the study.

The room was cold. Unnaturally cold.

Arthur Vance, a man who had turned ones and zeros into a ten-billion-dollar empire, was slumped over a glass-and-chrome desk. His eyes, wide and lifeless, stared at a blinking cursor on a fifty-inch monitor. A single, dark stain spread across the breast of his pristine white shirt.

“Locked from the inside,” Harding said, leaning against the doorframe. “Windows are sealed. We had to override the security to even get in. Coroner’s preliminary guess is a single stab wound, precise, probably a stiletto or an ice pick. No weapon found.”

Kincaid walked around the desk. No sign of struggle. No overturned chair. Just a dead man and a locked room.

“This whole place is a smart house, right?” Kincaid asked, his gaze sweeping the room. No vents large enough for a person, no hidden panels he could see.

“Top of the line. Vance’s own company designed it. ‘Ares,’ he called the AI.” Harding tapped his temple. “Genius. Controls the locks, lights, temperature, security. Everything. According to the logs, Mr. Vance initiated a full lockdown of this room at 10:00 PM. Voice command. No one in, no one out. He did it every night. Paranoia was his co-pilot.”

“When was the body found?”

“Midnight. The wife, Elara, said he always came out at 11:30 PM for a nightcap. When he didn’t, she got worried. She couldn’t open the door. She called his security chief, who also couldn’t get in. They finally overrode the system and… well.”

“So, the killer was either in the room before 10:00 PM and vanished, or Vance locked himself in and committed suicide with a weapon that then evaporated.”

“Looks that way,” Harding shrugged. “Like I said. A ghost.”

Kincaid knelt by the body, ignoring the cold that was starting to seep into his knees. He looked at Vance. Then he looked at the wall-mounted thermostat. The display read 55 degrees Fahrenheit.

“Why is it freezing in here?” Kincaid asked.

Harding blinked. “Ares system. Maybe it malfunctioned when he died.”

“Maybe.” Kincaid stood up. “I’ll talk to the widow.”

Elara Vance was in the grand lounge, a room so large it felt like a museum exhibit. She was half her husband’s age, wrapped in a silk robe, and staring out at the raging storm. She was beautiful, and she was putting on a very good show of being distraught.

“Detective Kincaid,” she whispered, dabbing at eyes that were perfectly, suspiciously dry. “Thank you for coming. The police… they’re so… procedural.”

“Mrs. Vance, your husband locked himself in his study at 10:00 PM. Where were you?”

“Here. In my wing. I was reading.” Her voice was breathy. “Arthur was obsessive about his 10:00 PM lockdown. He said it was the only time he could truly work, secure from… everything.”

“Secure from what? Or who?”

She hesitated, twisting a diamond ring on her finger. “Julian. His business partner. They had a terrible fight yesterday. Julian was shouting. Arthur was… cold. He told Julian he was dissolving the partnership.”

“Motive,” Kincaid murmured. “Where is Julian Thorne now?”

“I… I don’t know. He might be here. He has a suite on the floor below.”

“And the security chief? The one who opened the door?”

“Marcus. He’s been with Arthur for twenty years. He runs the entire security for the building.” She finally looked at him, her blue eyes wide and calculated. “You’ll find who did this, won’t you? It was Julian. It had to be.”

Kincaid met her gaze. “I’ll find what happened, Mrs. Vance.”

He found Julian Thorne in the penthouse’s private bar, nursing a scotch. Thorne was all sharp angles and expensive tailoring.

“Detective,” Thorne said, swirling the amber liquid. “Tragic. Utterly tragic.”

“You had a fight with him.”

Thorne laughed, a dry, humorless sound. “Who didn’t? Arthur was a tyrant. A brilliant one, but a tyrant nonetheless. Yes, we fought. He was about to scuttle a project that would have made us both another billion. He’d lost his nerve.”

“Where were you between 10:00 PM and midnight?”

“At the ‘Onyx Club’ downtown. Drowning my sorrows over said billion-dollar project. I have a tab and a dozen witnesses.” He leaned in, his voice dropping. “You want the killer? Look at the ice queen in the lounge. She just inherited the kingdom. Arthur was about to write her out of his will. He told me so himself this afternoon.”

Kincaid left him and went looking for Marcus.

He found the security chief in a small, dark office behind the kitchen. It was a control room, filled with monitors. Marcus was a stark contrast to Vance’s world of glass and light. He was a big man, built of solid, aging muscle, with a face that looked carved from granite.

“Detective,” he said, his voice a low rumble.

“You were with Vance for twenty years.”

“Twenty-two. I was his first-ever employee. Back when he was just a kid in a garage.”

“You run the security. But Ares runs the house. Who controls Ares?”

“Mr. Vance did. Primarily. Voice commands, or his personal tablet.”

“Who else has access?”

“Full admin override? Just me. For emergencies.” Marcus tapped a keyboard. A schematic of the penthouse appeared. “This is the log. Mrs. Vance called me to the study at 11:48 PM. I attempted a remote unlock. It failed. Mr. Vance’s lockdown protocol was absolute. I had to initiate a hard reboot of the room’s core system, which took ten minutes. We entered at 12:02 AM.”

“And before that? Between 10:00 and 11:48?”

“I was here. On patrol.”

“The log shows Vance locking the room at 10:00 PM. Voice command. Status: ‘Locked from Inside.’” Kincaid stared at the screen. “What about the thermostat? Why 55 degrees?”

Marcus’s expression didn’t flicker, but Kincaid caught it—a fractional hesitation.

“The system must have glitched. A power surge from the storm, perhaps.”

“The storm.” Kincaid looked at the monitors, at the feeds from the study. The body was still there, waiting for the coroner. “The room was locked from the inside. The wife and the partner both have motives, but one has an alibi and the other seems more interested in framing him. And you… you were just doing your job.”

“That’s correct.”

Kincaid turned back to Marcus. The air in the small room felt thick. “You know, I was a beat cop in the 90s. We had a case, an old woman in a brownstone. Dead of a heart attack, but her apartment was an icebox. Mid-July. The M.E. told me something I never forgot. Cold slows things down. Coagulation. Lividity. It muddies the time of death.”

Marcus remained perfectly still. “A ‘glitch,’ Detective.”

“Here’s what I think, Marcus.” Kincaid walked closer, his voice dropping. “I think you’re the ghost. You’ve been with him 22 years. You built this place with him. You probably even helped him design this damned Ares system.”

“Mr. Vance was the genius.”

“Was he? Or were you? He was the face, the name. You were the quiet man in the background, the one who made it all work. And he took the credit. He took all of it.”

Marcus’s jaw tightened.

“He wasn’t going to cut Julian out,” Kincaid continued, the pieces clicking into place. “He wasn’t going to cut Elara out. He was going to cut you out. Push you into early retirement. The last loose end from the ‘garage days’ who knew the truth.”

“You have no proof.”

“The log. I’ve been staring at it. 10:00 PM: ‘Voice Command: Lockdown.’ But just before that… 9:59 PM. There’s a missing block of data. Just thirty seconds. It’s not a glitch. It’s a wipe. You initiated a manual override at 9:59, before he gave the voice command. You let him lock himself in, but you kept a digital back door open for yourself.

“You waited. You let him work. Then, you slipped in. He wouldn’t have been surprised to see you. Just Marcus, the loyal watchdog. You stabbed him, once, quick and clean. A kitchen knife, probably. You took it with you.

“Then you went back to this room. You engaged the real lockdown remotely, sealing the room tight. You wiped the 30-second override from the log. But you made a mistake. You’re a security guy, not a forensic pathologist. You dropped the temperature, thinking you’d buy yourself a few hours, confuse the coroner. But you’re not an AI, Marcus. You’re human. And you forgot to set it back to normal.”

Marcus stared at the screen, at the static-filled feed from the study. The storm outside reached a crescendo, the thunder rattling the building to its foundation.

When he finally spoke, his voice was heavy, devoid of all emotion.

“He called me ‘good help.’ Yesterday. After 22 years. I was just… ‘good help.’ He said the company needed a ‘younger image’ for its security. He was going to give me a pension and a plaque.”

Marcus turned his gaze to Kincaid. There were no tears, just an abyss of cold, tired rage.

“Ares… I named it. It was my son’s name. He… he told me it sounded ‘strong.’ He didn’t even remember.”

Kincaid sighed, pulling a crushed pack of cigarettes from his pocket. “And the weapon?”

Marcus reached under his desk and placed a long, thin kitchen knife on the blotter. It was clean.

“I was washing it when Mrs. Vance called.”

Kincaid nodded, picking up the desk phone to call Harding. “You were right about one thing, Marcus. Vance wasn’t the genius. He was just the one who got the credit. And in the end, that’s what killed him.”
