THE RED SHOES OF FIFTH AVENUE: MY SIX-YEAR-OLD DAUGHTER DREW THE $38 CHRISTMAS SHOES WE COULDN'T AFFORD ON A BUS TICKET—UNTIL NEW YORK'S MOST RUTHLESS MAFIA BOSS RECOGNIZED THE PENCIL IN HER HAND

"They blew the gas main in the front bake-shop to bury the tunnel entrance!" Enzo shouted from the driver’s seat as he slammed the Maybach onto the sidewalk behind a hook-and-ladder fire truck.

"Enzo, stay locked inside this armored car with Rosie!" Dominic commanded, already throwing his black cashmere overcoat off in the backseat and pulling a heavy crowbar and a high-powered LED flashlight from the trunk pass-through. "If anyone without my badge comes within twenty feet of my niece, put them in the ground!"

"Wait—I’m coming with you!" I cried, grabbing the strap of my purse and jumping out into the freezing December slush right behind Dominic before he could shut the door. "The front stairs will be collapsed from the gas explosion, and you don't know the coal chute layout in the back courtyard! I’ve shoveled coal down that chute every winter for four years!"

Dominic looked at me through the swirling black smoke and falling snow—a five-foot-four bakery worker in a patched coat—and saw the exact same refusal to surrender he had seen when I stood in front of Rosie at Bergman’s.

"Stay one step behind me, Clara," Dominic said fiercely, catching my hand in his as we sprinted down the narrow, ice-slicked service alley beside the burning bakery while firefighters fought the blaze at the front awning on Steinway Street.

In the enclosed brick courtyard behind the bakery, the padlock on the iron coal-chute doors had been freshly cut with bolt cutters—and lying in the slush beside the ash bins was Anton Novak, groaning and clutching a bleeding gash on the side of his head where Uncle Vittorio’s men had struck him on their way out ten minutes ago!

Dominic dropped a knee onto Anton’s chest, pinning the sixty-year-old baker to the icy bricks.

"Where is he, Anton?!" Dominic roared over the crackle of the flames roaring through the first-floor rafters above us. "Did Vittorio take him out through the cold-storage warehouse, or is he still behind the oven?!"

"He’s still in Vault 14!" Anton wheezed in terror, blood running down his flour-stained collar. "Swear to God, Mr. Moretti, I kept him alive for four years! Vittorio wanted to kill him the night of the Red Hook fire, but he needed Michael’s live retinal scan every December twentieth at noon to unlock the Zurich trust dividend! Ten minutes ago, Vittorio got the final December scan, locked the heavy steel vault door from the outside, and severed the steam boiler pipe so the cellar would flood with scalding water before the fire department found him!"

I didn't wait for Dominic to finish questioning him.

I threw open the heavy iron coal-chute doors and scrambled down the steep steel slide into the dark, smoke-filled basement beneath the bakery.

Down here, the heat was suffocating. Above our heads, the massive twenty-ton brick hearth of the main bakery oven was groaning under the weight of the burning first floor, while three feet across the stone floor, a ruptured four-inch cast-iron boiler pipe was spewing boiling white steam and ankle-deep scalding water across the cellar!

Dominic landed on the coal pile right behind me, shielding my face from a shower of falling sparks with his body as he shone his tactical flashlight through the dense white fog toward the back of the brick oven.

There, set into the three-foot-thick foundation wall behind the flour racks, was the rusted iron door marked DANGER — HIGH VOLTAGE STEAM.

And bolted across the outside of the door was a massive steel drop-bar secured by a spinning brass combination wheel and a keyhole stamped V-14.

From the other side of the four-inch steel door came the faint, rhythmic pounding of a piece of iron pipe against metal—three short taps, pause, one long tap.

My heart stopped.

Three short taps, one long tap.

That was the exact secret knock Leo used to tap on our bedroom window in Astoria when he came home late from night carpentry jobs so he wouldn't wake baby Rosie!

"Leo!" I screamed at the top of my lungs, splashing through the rising hot water in my worn boots and slamming both of my palms against the hot steel door. "Leo, it’s Clara! I’m here! We’re right outside!"

The rhythmic tapping on the inside of the door stopped instantly.

Then, through the rusted brass speaking tube mounted beside the doorframe, came a voice I had heard in my dreams every single night for four years—hoarse, weak from smoke and heat, but undeniably alive:

"Clara?! Clara, get out of the cellar! The boiler pipe is going to blow the brick arch! For God’s sake, where is Rosie?!"

A sob tore out of my throat so hard my knees hit the flooded stones before Dominic caught me under the arms and hauled me up onto the dry wooden pallet beside the wall.

"Rosie is safe in my armored car out front, Michael!" Dominic shouted into the brass speaking tube, his voice cracking with four years of brotherly agony as he jammed the brass V-14 key from Leo’s toolbox into the heavy padlock. "Hold on, little brother! I’ve got the key!"

Dominic twisted the brass key with all his strength. The heavy secondary padlock popped open—but the central steel drop-bar didn't budge.

It was held in place by a three-wheel brass mechanical cipher lock set into the center of the bar.

"Dominic, you can't open the cipher without Vittorio’s six-digit code!" Michael coughed from inside the vault, where black smoke from the upper ventilation shaft was already being sucked down into his chamber. "And if you shoot the lock, the relocker pins will jam the bar permanently! Take Clara and Rosie and get out before the oven floor caves in!"

"I am not leaving you in here after four years, Leo Miller!" I cried, wiping the soot and tears from my eyes as I stared at the three brass number wheels on the lock—each wheel numbered from 00 to 99.

"Wait," Dominic said, his dark eyes narrowing on the brass lock plate. "Vittorio didn't set the combination on this vault door when it was built in two thousand and eighteen, Michael. Who installed the mechanical relocker on Vault 14 during the warehouse renovation?"

Silence from the speaking tube for two seconds.

"I did," my husband rasped from behind the steel. "Six years ago, before I left Brooklyn. Wait—Vittorio never changed the factory override wheel on the back tumbler!"

"What did you set the six numbers to six years ago, Leo?!" I shouted, my fingers already gripping the hot brass dial as the wooden ceiling beams behind us cracked with a terrifying roar.

"The day my real life started, Clara!" my husband cried out through a fit of coughing. "And the weight on the hospital bracelet!"

I didn't even have to think. Every mother knows those numbers until the day she dies.

December 14—Rosie’s birthday: 12 — 14.

And seven pounds, eight ounces: 07 — 08.

Wait—that was eight digits, and the three wheels only took three pairs of numbers!

I looked down at the third brass wheel, which was engraved with a weight scale symbol: OUNCES.

Seven pounds, eight ounces wasn't 07-08—in total ounces, seven times sixteen plus eight was 120!

With boiling water swirling around my ankles and burning timber crashing down onto the coal chute ten feet behind us, I spun the three brass wheels: 12 — 14 — 20.
