I've begun The King's Assassin, a biography of George Villiers, the Duke of Buckingham, who rose to power as the lover of King James I. In Dumas' The Three Musketeers, he is the over-wrought love of Queen Anne, whose diamond studs cause all the fuss before he is assassinated through the intrigues of Cardinal Richelieu and Milady de Winter. The biography is most interesting but the print is very small.
