SHE WAS TOLD TO USE THE SERVICE ENTRANCE AT HER SISTER'S LUXURY GALA — UNTIL THE MYSTERY BENEFACTOR STEPPED OUT OF THE LIMOUSINE

Dressed in a plain wool coat damp from the November rain in Mayfair, Hannah Miller stood quietly on the red carpet of the Dorchester ballroom while her younger sister smiled behind a glass of vintage champagne.

"I'm terribly sorry, Miss, but the kitchen delivery corridor is around the back," her sister Victoria said loudly enough for half the charity committee to hear, drawing a ripple of polite, cruel laughter from the velvet rope line.

"You invited me yourself last Tuesday, Victoria," Hannah replied evenly, holding out the cream-embossed card. "You said Mother wanted both daughters present for the hospital wing dedication."

Victoria plucked the card from Hannah's fingers and tore it cleanly down the middle, dropping the halves into a brass umbrella stand. "That was before we realized the anonymous patron funding the entire twelve-million-pound wing is attending tonight in person. We simply cannot afford anyone shabby at Table One."

The head doorman shifted uncomfortably, stepping forward to escort Hannah away from the flashbulbs.

At that exact moment, three sleek black Rolls-Royce sedans glided to a silent halt along Park Lane. Security guards in tailored earpieces fanned out across the pavement, and the hotel's managing director sprinted down the marble steps—walking straight past Victoria and stopping directly in front of Hannah.
