The Twelfth Hour by Ada Leverson

It is a long and golden summer in the Edwardian period. London is abuzz with gentlemen in tall hats and ladies in flowing silk, some with money, and others who want it badly. Love and marriage are the great game, but the adventure is vastly varied, depending on who is playing. Creatures of wit find it their most impressive subject; creatures of love are either pinnacled or torn apart by its demands.

Felicity, Sylvia and Savile Crofton, aged 25, 20 and 16 respectively, are deep in the melee. Felicity is married to Lord Chetwode, the man of her dreams, and is largely happy, but she is already feeling deeply the falling-off of contact as he pursues horseflesh and antiques across the country in ever-longer stays away.

Her younger sister Sylvia is very much in the market, according to her father, who has many ideas of whom she might marry, but particularly favours a Greek millionaire, Mr. Ridokanaki. He has no idea that her great love is his penniless secretary, Frank Woodville.

Their brother Savile, on holiday from Eton, has not only the spirited attentions of young Dolly Clive to contend with, but also his great passion for an opera singer, whom he loves from afar.

Somehow, all their problems must be brought to a satisfactory conclusion. A typically confident Savile tries to engineer a solution, but in the end it is love itself which cuts through.

This mischievously witty tale of love and intrigue, Leverson's first novel, was first published in 1907.
