Mercy of the Mafia Doctor (Costa Vendetta #10)

1. Amara

AMARA

Cold steel against a lock shouldn’t feel this much like a homecoming, but after ten years of chasing ghosts through other people’s ledgers, the bypass cable under my sleeve feels more honest than any badge I ever carried.

The West Loop is quiet tonight, a heavy, humid silence hanging over the brick warehouses and the trendy lofts, but this corner is different.

This building doesn’t have a sign. It doesn’t need one.

Anyone who knows what happens behind these reinforced doors isn’t looking for a Yelp review.

They’re looking for a miracle or a way to make someone disappear.

The tumbler gives way with a soft, mechanical sigh.

My heart doesn’t race. It doesn’t even skip.

When you’ve been running on pure spite and grief for a decade, your adrenaline system eventually just quits on you, leaving behind a cold, efficient engine that only knows how to move forward.

I slip inside, the air-conditioned chill of the clinic hitting my skin like a slap.

It smells of ozone and industrial-grade cleaner, a scent so sterile it feels hostile.

I don’t turn on a light. I don’t need to.

Having memorized the floor plans I swiped from the city’s digital archives three weeks ago, I found that half of them are already wrong, indicating a remodel that permits failed to capture.

Two steps left, eight steps straight, then improvise around whatever he’s changed.

My boots make no sound on the polished concrete.

My breath is a steady, even rhythm in the back of my throat.

Ten years. More than three thousand six hundred days since the world ended in a phone call and a stack of paperwork that didn’t make sense.

Curtis didn't die for a grand cause. He didn't die for a secret that could change the world. He died for forty thousand dollars. That was the price Alvarado Vane put on my brother’s head.

Forty grand to keep a paper trail buried in the red.

I reach the heavy oak door at the back of the hallway.

This is the inner sanctum. This is where Alessio Costa keeps the things he doesn't want the world—or even his family—to see. The Costa family’s doctor is a man of many talents, but the thing that makes him dangerous is what the city whispers about him: he keeps secrets like a vault.

Outsiders mistake the Costas for blunt force and old blood, but Alessio is the scalpel. He’s the quiet at the center of the storm. And if my intel is right, he’s been hunting the same ghost I have.

The keypad glowing faint blue is only the visible insult. The real lock lives behind it, nested in a biometric relay and a server that has no business being awake at two in the morning. I pull my bypass kit, fingers moving with a grace born of desperation.

My brother used to tell me I was too smart for my own good, that I should’ve been something normal like a teacher or a baker.

What I've turned into would be something he'd hate. He’d hate the way I can dismantle a high-security system in under ninety seconds.

It would probably annoy him that I haven't slept in a bed I owned since I was twenty-two.

But Curtis is dead, and the man who signed the check for his murder is still breathing somewhere in this city.

The keypad chirps once, and the lock disengages.

I push the door open, slipping into the office.

It’s larger than I expected, filled with the shadows of heavy furniture and the faint hum of a server rack in the corner.

I head straight for the desk. I’m not looking for money.

I’m not looking for drugs. I’m looking for the sub-ledger—the one thread of Vane’s architecture he couldn’t scrub, the index that points at everything else.

I’ve spent a decade following the scent of Vane’s money.

It’s a phantom limb, always there, always out of reach.

It’s moved through offshore accounts, shell companies, and laundered construction contracts, but it always leads back to the same source.

A ghost financier who faked his own death more than a decade ago. A man who thinks he’s invisible.

My fingers find the latch on the bottom drawer of the desk. It’s locked, of course. I reach for my pick, but a sudden flash of light from the street catches the corner of my eye.

I freeze. My hand stays hovering over the drawer.

I move to the window, peeling back the edge of a heavy curtain just enough to see the street.

A black SUV is idling at the curb. Two men are getting out, their movements practiced, heavy.

They aren't cops. Cops have a certain way of standing, a jittery energy even when they're trying to be cool.

These men are solid. They move as if they own the sidewalk.

Bellantis.

I recognize the SUV—same plate a Savannah surveillance photo caught outside a Bellanti shell two years ago—and the way the driver adjusts the weight under his jacket.

They’re not here for a book. They’re here for me—for whatever my data has been dragging into the light—and to make sure it burns with me.

Either way, my exit strategy just went up in flames.

I drop the curtain and turn back to the room, my mind spinning. I can’t go out the front. The fire escape is in the hallway, but it’s too exposed. I need to find the ledger and find another way out.

"You’re looking in the wrong place."

The voice is deep, a low rumble that vibrates in the floorboards and settles right in the center of my chest. It’s not a shout. This is not a threat. It’s a statement of fact, delivered with the calm authority of a man who has never been told no in his entire life.

I don't scream. I don't jump. I just stop. My hand goes to the small knife tucked into the small of my back, my fingers curling around the hilt. I turn slowly, my eyes adjusting to the darkness of the corner where the voice came from.

He’s sitting in a high-backed leather chair, almost swallowed by the shadows, and I understand he let me get this far—needed to see exactly what I came for, and to watch whoever followed me in.

I can only see the outline of him—the broad set of his shoulders, the height of him that even sitting down feels oppressive.

As he leans forward, the blue light from the keypad catches the silver at his temples and the sharp, dangerous line of his jaw.

Alessio Costa.

He doesn't look like a mob doctor. He looks like a king who decided to retire to the underworld.

His hands are resting on the arms of the chair, large and scarred, the fingers long and elegant but capable of terrible things.

On his left forearm, a caduceus tattoo peeks out from beneath the rolled-up sleeve of a charcoal shirt.

"The real trail isn’t in that desk," he says, his voice like gravel and silk. "What’s in there is bait—a decoy index I planted to see which Bellanti came sniffing. You’re not who I expected."

"I'm not a common thief," I say, my voice steady despite the way my heart is finally starting to hammer against my ribs. Sarcasm is my only defense, and I wield it like a shield. "I’m an uncommon thief. I have a resume and everything."

He doesn't smile. He doesn't even blink. He just watches me with eyes that feel like they’re peeling back the layers of my skin to see what’s underneath.

"Amara Osei," he says.

The sound of my name in his mouth makes the hair on my arms stand up. It’s not just that he knows who I am. It’s the way he says it, like he’s been saying it to himself for a long time. Like it’s a word he’s already memorized.

"Atlanta. Savannah. New York. Chicago. You didn’t hide your trail as well as you thought, Amara. You just hid it from men who didn’t know what to look for."

"I guess I should've worked on my stealth," I mutter, my grip tightening on the knife. "How long have you been sitting there?"

"Long enough to know you’re better at picking locks than you are at checking your six," he says, standing up.

He’s massive. The profile I read said six-three, but in this room, in this moment, he feels like a mountain. With a predatory grace, he moves with a fluidity that shouldn't belong to a man that size. He doesn't move toward me, not yet. Mirroring my recent move, he walks to the window.

"The men outside are Bellantis," he says, his back to me. "They’ve been following you since you left your apartment at Lake and Aberdeen. They let you do the breaking in so they could catch you inside. You’re the intruder they blame, the body they leave, the fire they light after.

The evidence dies with the building—and with you. "

"Why tell me?" I ask, my eyes scanning the room for an exit he might have missed. "You're a Costa. Your family has been at war with them since before I was born. Why not just let them have me?"

He turns back to me, and finally, I see the intensity in his gaze. It’s not anger. It’s something much more dangerous. It’s obsession.

"Because you may have the one thing I’ve been missing for eleven years," he says, stepping into my personal space.

He’s close enough now that I can smell him—sandalwood, old paper, and something sharp and metallic.

He doesn't touch me, but the air between us feels charged, like the moment before a lightning strike.

I should be terrified. My brain is screaming at me to run, to fight, to do anything but stand here and drown in the depth of his dark eyes.

But I don't move.

"What's that?" I whisper.

"The motive," he says. "I have the money. I have the names. I have the dates. What I don’t have is the reason Vane’s trail keeps circling back to the night my family died."

I feel the breath hitch in my throat. My brother’s death wasn't just a random act of violence. It was a piece of a much larger puzzle. One that this man has been building in the dark for over a decade.

"Curtis," I say, the name a raw wound in the silence of the room.

Alessio’s expression softens, just for a fraction of a second, before the mask of the stoic protector slides back into place.
