Death of a blue blood - Donald Bain

Jessica Fletcher and her friend Scotland Yard detective inspector George Sutherland are invited to attend a New Year's Eve Ball at Castorbrook Castle, thanks to her British publisher. Shortly after arriving in the idyllic English countryside, Jessica discovers the body of a lady's maid in the garden. While their host, Lord Norrance, his snobbish third wife, other members of the household, and party guests squabble over the tragic death in tight-lipped, perfectly mannered, thoroughly British style, family relations are strained as old wounds are reopened.
