After the battle of Acre, we join the Knights Templar in Paris where Landry, a veteran of the Holy Wars, fears that the Order has lost its way. When the blood of a brother is shed, Landry and the Templars are forced to take up their swords again.

Landry and Parsifal search for a killer. The unexpected arrival of Pope Boniface in Paris threatens De Nogaret's carefully laid plans.

Landry and Gawain meet a mysterious woman who claims she can lead them to the Grail; Joan hears of an attack on Navarre; De Nogaret devises a way to improve his standing with King Philip.

Landry seeks the help of Jacques de Molay, the Temple Grand Master; Queen Joan plots her escape.
