The King's Spies: An 11th Century Mystery (Paperback or Softback)

A Sir Geoffrey Mappestone mystery. March 1102 March 1102, and Robert de Belleme, the Black Earl of Shrewsbury, is summoned to appear before King Henry's Easter Court, to answer for siding with the King's older brother, the Duke of Normandy, in an attempt to steal the King's throne. Meanwhile, in the crowded and dangerous streets of Southwark, south of the river Thames, Crusader Knights Sir Geoffrey Mappestone and the hearty Sir Roger of Durham witness a man murdered by hanging from the window of the Crusader's Arms Inn. But this is not just any man, he is the illegitimate nephew of Robert de Belleme, and had apparently been holding a meeting with two mysterious men. In fact, it turns out the inn has been used for many meetings of the earl's spies, and there are plans afoot to obtain a terrible weapon to use against the King, one that the Crusader Knights remember with a terrible fear from the Siege of Jerusalem Greek Fire. Solving the murder is only the first step in uncovering the plot against the King.
