Dark Gold, A Robert Sable Mystery, Published 2003 at Amazon

Dark Gold, the 4th Robert Sable Mystery is the unifying pivot of the series.

             Alaska State Trooper Robert Sable is a man with a troubled past. He watched his wife and son die at the hands of his enemies and, having weathered that tragedy, has recently lost his fiancé, Lisa Riddell, in a bus crash.  Guilt is driving Sable; neither his physical strength nor his psychic gifts were enough to protect the people he loved.  Sliding into a lifestyle of alcohol abuse and risk-taking, it is uncertain if Sable himself will survive.

            Sable's partner, Josh Sampson, is the son of a World War II pilot lost in a plane crash in Alaska.  Sampson knows the secret of the C-46's last flight: it carried a fortune in gold.  What he doesn't realize is how ruthless Philip Martin Frost, the son of another crewmember on the doomed aircraft, is prepared to be.  Frost, a merciless killer, hides behind a mask of respectability.  He eliminates Josh Sampson without a qualm and prepares to kill Robert Sable, on the assumption that Sable knows everything.

            However, Sable knows nothing of the lost riches.  Driven by Sampson's death, Sable and new partner Aaron McCabe, tackle the clues that Sampson left behind.  Slowly, they piece together the puzzle of the lost plane and its cargo.  Confronted by competing FBI agents, crooked cops, hired assassins and hardened crime bosses, they try to track down the gold and stop the cycle of killing. Along the way Sable rediscovers his self worth and has another chance at love.
