At a moonlit Indian ruin—where "thieves of time" ravage sacred ground in the name of profit—a noted anthropologist vanishes while on the verge of making a startling, history-altering discovery.

And as blood flows all too freely, Navajo Tribal Policemen Joe Leaphorn and Jim Chee must plunge into the past to unearth an astonishing truth and a cold-hearted killer.
