Murder at Buxley Manor by Leena Clover

An English manor house, intrepid dowagers, spirited Bright Young Things . . . and Murder! England 1921. Lady Elizabeth Gaskins is throwing a big party to celebrate her birthday. But when an odious guest gets killed and steals her thunder, her father, the Earl of Buxley, becomes a suspect. After all, he came to blows with the dead man in front of several witnesses. Determined to find out who murdered his childhood friend, Lord Buxley summons a detective from Scotland Yard. Not to be outdone, Lady Bess and her spunky cohorts, the oldest Dowager Countess and great aunts, embark on a hunt for the killer. Aided by servants, friends, and villagers, fortified by copious amounts of Darjeeling and kedgeree, these feisty women will not let minor obstacles deter them.
