The Lady Grace Mysteries: Assassin

My name is Lady Grace Cavendish, and I''m Her Majesty Queen Elizabeth''s favourite Maid of Honour. Everyone thinks growing up at the Royal Court is all parties and feasts and jewels - but mysterious, dangerous things always seem to happen! And because I am small and smart and very good at sneaking around, the Queen has made me her very own special secret investigator.
Last night was the Valentine''s Ball, and I was supposed to pick a suitor there (boring!). But later on, one of them was found dead - with a dagger in his back! And it''s up to me to solve the mystery and find the killer . . .
