A mix of Wodehousian farce and whodunit that is sure to appeal to Downton Abbey fans, Lady Georgie - 35th in line to the throne, flat broke and struggling to survive in the Great Depression - is embroiled in a mystery.

She may be thirty-fifth in line for the throne, but Lady Georgiana Rannoch cannot wait to ring in the New Year - before a Christmas killer wrings another neck . . .

On the first day of Christmas, my true love gave to me - well, actually, my true love, Darcy O'Mara, is spending a feliz navidad tramping around South America. Meanwhile, Mummy is holed up in a tiny village called Tiddleton-under-Lovey with that droll Noel Coward! And I'm snowed in at Castle Rannoch with my bumbling brother, Binky, and sourpuss sister-in-law, Fig.

So it's a miracle when I contrive to land a position as hostess to a posh holiday party in Tiddleton. The village is like something out of A Christmas Carol! But then there are three deaths, so-called accidents. Perhaps a recent prison break could have something to do with it . . . that, or a long-standing witch's curse. But after Darcy shows up beneath the mistletoe, anything could be possible in this wicked wonderland.
