6 books in one volume:

#1 - Queen Lucia
Mrs. Lucas, Lucia to her intimates, resides in the village of Riseholme, a pretty Elizabethan village in Worcestershire, where she vigorously guards her status as "Queen" despite occasional attempts from her subjects to overthrow her. Lucia’s dear friend Georgie Pillson both worships Lucia and occasionally works to subvert her power.

#2 - Miss Mapp
Arch-schemer and social climber, Miss Mapp spends her days using opera glasses and a notebook to chart her neighbors' affairs. Among her interests are Major Benjamin Flint, whom she has been trying to marry for years.

#3 - Lucia in London
Here is Lucia in one of her most extraordinary adventures: can she conquer her new home of London, and still hold her societal ground over the stately country mansions of Riseholme as well? Will the citizens of Riseholme - hurt and maddened by Lucia's desertion for the great city - carry out their plot of revenge?

#4 - Mapp and Lucia
Subtly brilliant comedy of social rivalry between the wars. Emmeline Lucas (known universally to her friends as Lucia) is an arch-snob of the highest order. In Miss Elizabeth Mapp of Mallards Lucia meets her match. Ostensibly the most civil and genteel of society ladies, there is no plan too devious, no plot too cunning, no depths to which they would not sink, in order to win the battle for social supremacy. Using as their deadly weapons garden parties, bridge evenings and charming teas, the two combatants strive to outcharm each other - and the whole of Tilling society - as they vie for the position of doyenne of the town.

#5 - The Worshipful Lucia (aka Lucia's Progress)
Both Lucia and Mapp stand for election to the Town Council, and Lucia speculates in gold shares. While redecorating Miss Mapp's house, Lucia discovers and hide the remains of a Roman Villa. Excitements ensue!

#6 - Trouble for Lucia
Lucia learns to ride a bicycle, and we live through the saga of Blue Birdie (Mrs. Wyse's dead budgerigar [parakeet] invoked in a seance). Lucia and Georgie renew their acquaintance with the operatic diva Olga Braceley and the composer Cortese, but nobody in Tilling believes her when she claims to have entertained a duchess overnight. Lucia becomes Mayor of Tilling and Miss Mapp is appointed her Mayoress.
