The Hole in the Ocean

SOME SECRETS ARE BURIED FOR A REASON. OTHERS WERE NEVER MEANT TO BE FOUND.

Harbor

In Trieste, CIA officer Cole Hardin finds a murdered information broker and a number that should not exist outside a classified program. Three days later, a U.S. Navy vessel vanishes in the Gulf of Oman. The official account arrives quickly; the questions stop even faster.

Hardin follows evidence through shipyards and defense contractors as access narrows and geopolitical pressure builds. He must find out what happened before his search puts the people he means to protect in danger.

Story-grounded details beyond the mission brief.

The free-port city

Trieste’s Porto Franco lets goods sit in bonded warehouses and be repacked before they move on—a detail that gives the port’s ordinary trade an opaque edge.

A report with blanks

The missing-vessel notice gives no name, flag, tonnage, type, or last known position: basic identifiers Hardin expects to see in a naval report.
