The Color of Death by Elizabeth Lowell

The name Elizabeth Lowell has become synonymous with electrifying fiction that seamlessly combines suspense, intrigue, and passion. And now the phenomenal New York Times bestselling author brilliantly displays her incomparable talents in a story of treachery, greed, conspiracy, and murder that will hold the reader spellbound until the final word.

It is the opportunity of a lifetime for Kate Chandler, the chance to cut seven rare, priceless sapphires and solidify her reputation as a world-class jewel cutter. But something goes horribly, tragically wrong during what should have been a simple transfer of goods. The sapphires vanish without a trace. Missing also is the man Kate trusted to transport the gems: her half brother, Lee, who now, quite possibly, is dead. And suddenly she is on the run, pursued by federal agents who suspect her of being the criminal mastermind of a cunning bait-and-switch scheme.
