Chapter 4 - The Shadow in the Yard

When we reached the living room, the scene was pure chaos.
The electronic cardiac monitor Dr. Sullivan had attached to Rex's chest was beeping erratically, emitting high-pitched warning tones that pierced the heavy air.
Rex was thrashing weakly against the floor, his eyes rolled back, and white foam bubbling at the corners of his dry lips.
"His heart is throwing premature ventricular contractions!" Dr. Sullivan shouted over the alarm, frantically drawing liquid from a brown glass ampoule into a large syringe. "The digitalis toxin is causing a massive potassium drop! If I can't stabilize his electrical rhythm in ninety seconds, he will go into full cardiac arrest!"
"Do whatever it takes, Sullivan!" Luca roared, dropping onto his knees in the puddle of spilled water and wrapping his powerful arms around Rex's thrashing shoulders. "Hold on, Rex! Daddy's got you! Look at me, boy!"
Dr. Sullivan plunged the needle directly into the injection port of the IV line, pushing the lidocaine dose with steady, deliberate force.
I fell to my knees beside Rex's hindquarters, using a clean towel to wipe the warm foam from his muzzle, praying every prayer I had ever learned in Sunday school.
"Stay with us, Rex," I sobbed openly, stroking his matted fur. "Please don't let them win. Please stay."
For forty agonizing seconds, the monitor continued its frantic, terrifying scream.
Luca held the giant dog tightly against his chest, whispering ancient Sicilian blessings into the dog's ear, his tears dripping freely onto Rex's graying coat.
The ruthless mafia boss who had brought the entire underworld of Illinois to its knees was weeping openly over a dying animal.
Then, with a suddenness that made everyone freeze, the sharp alarm slowed.
Beep... beep... beep... beep.
The jagged red line on the small monitor smoothed out into a steady, rhythmic sinus wave.
Rex's violent tremors ceased, his limbs relaxing against the carpet as he drew in a deep, unobstructed breath of cool air.
His brown eyes slowly fluttered open, clearing slightly from the milky haze that had clouded them for days.
Rex turned his head weakly, his rough tongue making a single, loving swipe across the back of Luca's hand.
Luca buried his face in the thick scruff of Rex's neck, letting out a ragged, trembling breath of pure relief.
"Good boy," Luca whispered brokenly. "That's my good boy."
Dr. Sullivan slumped back against the sofa, wiping cold sweat from his forehead with a trembling forearm.
"The lidocaine counteracted the arrhythmic surge, and the IV fluids are finally clearing the metabolic acid from his blood," Dr. Sullivan said, his voice shaking with exhaustion. "He is far from out of the woods, but his kidneys are producing urine again, and his pulse is holding strong."
"Thank you, Doctor," Luca said quietly, never removing his hand from Rex's chest. "You will be compensated beyond your wildest imagination for what you did tonight."
Suddenly, the mansion's interior lights flickered twice and died completely, plunging the grand room into absolute pitch blackness.
A split second later, the heavy emergency generators kicked on in the basement, bathing the grand hall in eerie, low-wattage red security illumination.
Matteo's voice crackled frantically through Luca's radio earpiece, loud enough for me to hear every word.
"Boss! The exterior fiber-optic lines just got severed at the perimeter gate!" Matteo reported, gunfire echoing faintly in the background over the transmitter. "We have three blacked-out SUVs crashing through the southern checkpoint right now!"
Luca reached down to his hip, his face instantly transforming from a grieving dog owner into a stone-cold general of war.
"Who is it?" Luca demanded into his lapel mic.
"It's the Castiglione tactical crew!" Matteo shouted over the stuttering bark of automatic weapons outside. "Marco Bellini is with them! They know the gala plot was exposed, and they are moving to wipe this house before you can mobilize the family!"
Rex's ears suddenly twitched upright despite his severe weakness.
The elderly dog turned his head toward the reinforced glass patio doors leading to the rear gardens, his nostrils flaring as he tested the air filtering through the room's vents.
Rex let out a sharp, decisive bark that echoed off the high ceiling like a thunderclap.
"Claire, Sullivan, take Rex into the reinforced safe room behind the wine cellar immediately," Luca ordered, his voice cold and commanding as he racked the slide of his firearm.
"Mr. Moretti, he can't walk!" I protested, terrified for both the dog and our lives.
"Then use the heavy wool blanket as a stretcher between the two of you!" Luca commanded, pulling two spare magazines from his pocket and snapping one into his weapon. "Lock the steel vault door from the inside and do not open it for anyone other than me or Matteo!"
Rex growled again, struggling to push himself up on his front paws, his loyalty driving him to stand between Luca and the impending danger despite his failing body.
"No, my brave boy," Luca whispered, pressing Rex gently back down onto the blanket. "You did your job. You warned me. Now it's my turn to protect you."

Dr. Sullivan and I grabbed the four corners of the heavy blanket, lifting Rex's weight with all our combined strength, and hurried down the narrow stone stairs toward the reinforced cellar.
As the heavy vault door swung shut behind us, the deafening sound of shattering glass and heavy automatic gunfire exploded from the grand foyer above.
