Other name: Silver Triangle;
Summary: Marlee, an agent of the advanced civilization Central on the planet Blue Ear, finds himself on a mission to track down the troubadour Lagthorin. His mission leads him to the planet Corundum, where he finds the elusive musician and subsequently dies. Back at Central, he is regenerated into a new clone, Marlee Two, who sets off once more, drawn back to Lagthorin and her song. And so the strings of fate guide Marlee forward, inescapably intertwined with both the events on the planet Corundum and, 30,000 years across time, with the long-extinct race of the planet Silver Triangle.
