Navy lieutenant Eli Mercer has spent his career trusting systems that can be verified. When an Australian evidence package points to a hidden archive in the Pacific Northwest, he finds a backdated destruction order—and only days to reach the records that could finally clear his father’s name. Forensic financial investigator Rosalie Tanaka can follow money through any shell company, but she refuses to call a theory proof. Together, they trace vanished settlement funds from a Bremerton records annex across Puget Sound to a locked vault inside a decaying shipyard. Someone has already begun erasing the trail. Legal obstruction turns to sabotage, and fire and rising water make the search deadly. If Eli and Rosalie cannot authenticate and release the archive before Friday, the Blackwater conspiracy will disappear with it—and twenty-six years of lies will become permanent. The Iron Vault is a clean action-adventure thriller with procedural suspense and a slow-burn romantic undercurrent. It is Book 3 of The Mercer Files but can be read as a standalone.
