by S.F. BaumgartnerPublish: Nov 03, 2026 Series: The Mercer FilesThriller Mystery Action & AdventureBook Overview
Three brothers. Three investigations. One conspiracy.A dead rig.
A lost claim.
An iron vault.
The Mercer brothers follow three separate investigations spanning the Gulf Coast, Australia, and the Pacific Northwest—each discovery exposing another piece of a conspiracy protected for decades.
In Black Gold Secret, a storm-exposed offshore rig reveals evidence that the Blackwater disaster was never an accident.
In The Lost Claim, an erased Australian mining claim leads to forged records, shell-company money, and a trail someone will kill to destroy.
In The Iron Vault, a hidden Pacific Northwest archive holds the master evidence that could finally expose the people behind it all.
To reveal the full chain—and clear their family’s name—the brothers and their allies must recover, authenticate, and release the proof before their enemies bury it forever.
The Mercer Files Complete Trilogy brings all three novellas together in one collection filled with clean action-adventure, conspiracy suspense, dangerous discoveries, and restrained romantic undercurrents.
Includes:
• Black Gold Secret
• The Lost Claim
• The Iron Vault
