I spent six weeks creating a special mermaid performance for my brother’s bride, only to be publicly humiliated—then she asked why he’d accused me of trying to steal their money.

The crawl through the horizontal intake pipe was forty feet of pure claustrophobia.

The concrete walls were lined with sharp, encrusted oyster shells that scraped against the tough fabric of her drysuit with a sound like fingernails on a chalkboard. The water rushing around her shoulders was freezing, but inside her rubber suit, Maggie was sweating, her breath coming in ragged, controlled bursts.

Ten feet. Twenty feet.

Above her, she could hear the structural groaning of the building. The resort was settling on its pilings as thousands of tons of sea water shifted into the basement.

Then her light caught an obstruction.

A heavy, stainless-steel security grate blocked the end of the conduit—installed twenty years ago when the resort renovated the lower level to prevent divers from entering the private viewing moat.

Maggie pulled herself up to the grate. Through the square iron bars, she could see light.

Not sunlight, but the flickering, dying yellow light of the hotel’s emergency halogen beacons.

She pressed her mask against the bars and looked into the Lower Coral Room.

The scene was a nightmare.

The room was eighty feet long and forty feet wide, designed as a luxury underwater cocktail lounge with ten-foot-high panels of four-inch-thick curved acrylic glass looking out into the inlet.

The water in the room was already five feet deep.

Tables of white linen, silver trays, floral arrangements, and mahogany chairs were floating like wreckage in a flooded hold. The water had reached the level of the wall sconces, which were hissing and throwing off showers of blue sparks before dying into blackness.

At the far end of the room, standing on top of the heavy mahogany bar—the highest point left in the chamber—were three people.

Elise was there.

Her wedding dress was completely ruined, the skirt torn away to the knees, her bare shoulders shivering violently under the cold spray dripping from the ceiling. In her arms, she held Leo, her sister’s seven-year-old son. The boy was crying silently, his small face buried in Elise’s neck, his tiny blue suit soaked through.

Lying across the top of the bar beside them was Arthur Sterling.

The old shipping tycoon was pale as parchment, his eyes half-closed, clutching his left arm against his chest. His white shirt was soaked, his breathing shallow and rapid.

The water was six inches below the surface of the bar.

And the acrylic viewing panels at the front of the room—the massive windows looking out into the ocean—were beginning to fail.

Under the unmitigated pressure of the nor'easter’s high tide, the central window had bowed three inches inward. A spiderweb of white stress fractures was creeping across the lower left corner of the acrylic, whistling with a terrifying, high-pitched screech as jets of pressurized water shot forty feet across the room like needles.

If that panel blew, thirty thousand gallons of ocean water would hit the room in four seconds. Elise, Leo, and Arthur would be pulverized against the back concrete wall before they even had time to scream.

Maggie didn't have time to use the cutting torch. The heat would compromise the surrounding concrete and crack the acrylic faster.

She had the four-pound wrecking bar.

Maggie found the four anchor bolts securing the old grate to the concrete conduit collar. The concrete around them was soft from forty years of salt exposure. She jammed the point of the bar behind the top left mounting plate, braced both fins against the opposite side of the pipe, and drove the steel bar with all the force of her hips.

*CLANK!*

A chunk of gray aggregate broke loose.

She struck it again. *CLANK!*

The bolt popped free with a shriek of twisted metal.

She moved to the second bolt. Her right shoulder was burning with lactic acid, her knuckles scraped raw where the rubber glove had torn against an oyster shell. Her dive computer was beeping an urgent low-air alarm: **500 PSI. FIVE HUNDRED PSI.** She had less than three minutes before her tanks were empty.

*“ELISE!”* Maggie screamed through her mask, but the sound was muffled into a wet grunt.

She slammed the bar against the third bolt. It sheared clean.

Maggie grabbed the heavy iron grate with both gloved hands, planted her boots against the conduit lip, and tore the grate out of the wall like an iron tooth.
