Start of the Kalas cycle. Duncan and Anne attend a musical performance by a group of European monks, led by Duncan's old friend Immortal Brother Paul. Paul discovers that Immortal Kalas is the promoter who arranged the tour, so that he could get Paul off holy ground and settle an old score by taking his head. In flashback to 1658 Europe, Duncan finds a monastery run by Brother Paul where Immortals can retreat, and Kalas is the chief singer as well as a copyist. Another visiting Immortal, Timon, gives Duncan "Macbeth" and offers to teach him to read it. Later, Duncan suspects Kalas of treachery, and he and Paul confront Kalas. In modern day, Kalas concentrates on getting to Duncan by hurting those he loves: he frames Anne for the deaths of two patients and Joe for selling drugs at his bar.
