My passenger had less than a minute to breathe, three intimidating men were watching my every move, and no one at 37,000 feet seemed to understand what was happening. Then the stranger grabbed his throat, looked straight at me, and I realized something terrifying: if I didn't act immediately, the man in seat 2A might die in front of me.

The sound of splintering wood echoed down the narrow brick stairwell like a cannon shot.

"Move! Down! Go!" Marcus growled, pushing me toward the steep iron stairs.

I didn't argue. I grabbed the cold iron handrail and hurled myself down the steps, my flight attendant skirt ripping slightly along the seam as I took the stairs two at a time. My heart was pounding in my ears, drowning out everything except the frantic slapping of our shoes against the metal steps.

Above us, heavy footsteps exploded into the service corridor.

"Clear the floor! Search the rooms!" a sharp, commanding voice bellowed from above.

"They found the service door!" Leo gasped from behind me, clutching his bag of laptop drives to his chest like a life preserver. "Marcus, they're right behind us!"

"Keep moving!" Marcus shouted, pulling his Sig Sauer from his holster. He stopped at the fifth-floor landing, turned upward, and fired three rapid shots into the stairwell ceiling.

BANG! BANG! BANG!

The thunderous roars in the enclosed brick space were deafening. Plaster debris and dust rained down on us like gray snow. High above, muffled curses and the sound of bodies scrambling for cover proved Marcus’s warning shots had worked. It had bought us ten seconds.

We burst out of the stairwell onto the third floor, entering a brightly lit, industrial service hallway filled with stacks of clean laundry, industrial ironers, and giant wheeled linen carts. The air was warm and smelled heavily of bleach and steam.

"In here!" Marcus pointed toward a heavy double steel door at the end of the hall.

"Is that the lobby?" I panted, wiping sweat and plaster dust from my eyes.

"No, it's the laundry service freight elevator," Marcus said, shoving through the doors. "It drops straight down to the underground loading dock on Walton Street."

He slammed his hand against the oversized wall button. A yellow light above the doors flickered slowly. 4... 3... 2... The heavy elevator was moving down from the upper floors, painfully slow.

"Come on, come on," Leo whimpered, frantically hitting the button over and over. "They’re coming!"

At the far end of the laundry hallway, the stairwell door burst open.

Three men stepped into the light. They weren't wearing suits like the security detail on the plane. They wore dark tactical jackets, baseball caps pulled low, and carried sleek, suppressed automatic pistols. Professional hitmen.

"There!" one of them yelled, raising his weapon.

"Down!" Marcus bellowed, grabbing the back of my collar and tackling me to the linoleum floor just as a hail of muffled gunfire shattered the air.

Thwack! Thwack! Thwack!

Bullets tore into the soft drywall above our heads, sending clouds of insulation scattering across the hallway. A glass jar of industrial detergent exploded near my head, splashing hot blue liquid across my legs.

Marcus returned fire from the ground, aiming calmly over the top of a metal laundry cart. A hitman stumbled back as Marcus’s round hit him squarely in the chest plate.

DING.

The heavy steel doors of the freight elevator finally slid open with a slow, mechanical groan.

"Get in!" Marcus yelled, pushing me and Leo into the deep, wood-paneled elevator cage.

I scrambled across the steel floor, dragging myself into the corner. Leo lunged inside behind me. Marcus fired two more shots down the hall to force the remaining gunmen behind a stack of linen carts, then dived into the elevator backwards, hitting the emergency door-close lever with the butt of his gun.

The heavy steel gates groaned as they began to pull together.

Through the narrowing gap, I saw the lead hitman break cover, sprinting down the hallway with his silenced weapon raised. He fired twice.

THUMP! THUMP!

The bullets punched through the outer brass doors just as they locked shut. One round struck the control panel in a shower of brilliant blue sparks.

The elevator lurched violently. The cables above us shrieked in protest, and for one sickening, stomach-dropping second, we fell in freefall before the emergency mechanical brakes slammed on with a violent, metal-screeching crunch.

The elevator jerked to a sudden halt, suspending us in total darkness between floors.

"Is everyone alive?" Marcus’s voice cut through the pitch-black space, remarkably steady despite his heavy breathing.

"I... I think so," I sobbed, clutching my knee where I had hit the iron floor. "Leo?"

"I'm okay," Leo stammered, his teeth chattering uncontrollably. "My hard drives are okay."

A beam of bright white light cut through the dark as Marcus clicked on a small tactical flashlight mounted to his pistol. He swept the beam over us. I was covered in dust, my uniform torn, my hands scraped bleeding—but I was whole.

"We're stuck," I said, staring at the shattered control box oozing thin grey smoke. "Marcus, we're trapped in an elevator shaft with three armed men above us!"

"We aren't trapped," Marcus said calmly. He lowered his gun, looked up at the ceiling of the freight elevator, and pointed the flashlight upward.

There was an emergency escape hatch in the iron roof.

"Leo, give me a boost," Marcus commanded.

"Wait," I said, leaning against the wall as I stood up. "Where does that hatch lead?"

"To the secondary counterweight shaft," Marcus replied, grabbing the metal lip of the hatch and flexing his massive arms to swing himself up into the dark abyss above. "It opens into the subterranean tunnels beneath Lake Shore Drive. Built in 1920 to haul coal into the hotel furnace."

He reached his large hand down through the open hatch.

"Give me your hand, Evelyn," he said, his eyes reflecting the bright white light of the tactical torch. "You survived a murder attempt at 37,000 feet. I'm not letting you die in a hotel basement."

I looked up at his outstretched hand. I had no weapon, no phone, no money, and no identification. Everything I owned was in my rolling suitcase back in Suite 812. All I had left was my life and the man who had dragged me into this nightmare.
