Feud (The Grace Mysteries) by Lady Grace Cavendish

There is much excitement at Court as the famous painter Levina Teerlinc arrives to paint the Queen's portrait. The Maids of Honor are recruited to help entertain the Queen during the sittings, and to pose for the painter while the Queen is busy. They love being in the studio but have to beware as deadly poisons are used in some of the paints! One of Lady Grace's fellow Maids of Honor, Carmina, begins to act rather strangely--she seems confused and always tired. Her family has recently been involved in a feud with another noble family after her father was killed in a jousting tournament--is it possible that Carmina is being poisoned? Could the painter or her assistants be involved? Can Grace solve the mystery and discover the truth behind the strange happenings at Court?
