An Israeli Agent Infiltrates

An Israeli Agent Infiltrates
A long cover
Arie Levy infiltrates Benedict’s organization while posing as Khali Habash, a plasma physicist. His family life and intelligence work remain divided between different identities.
A mission in the deep
The Proteus assignment takes him to the Mariana Trench, where he hopes to learn what Benedict is hiding. His role links the opening disaster to an international intelligence struggle.
Heath Joins the Expedition

Heath Joins the Expedition
A scientific cover
Heath Williams joins the Benthos expedition as a paleo-biologist, but he is actually a CIA agent seeking evidence about Benedict’s fusion project. He maintains his cover by studying marine fossils.
A second layer of secrecy
Heath’s mission overlaps with Arie’s but does not initially connect them. The crew is surrounded by people gathering information for different governments and purposes.
A Warning from the Fossil

A Warning from the Fossil
Scientific evidence
Heath identifies a recent Kronosaurus fossil and connects the remains to the attackers. He warns Benedict that the creatures hunt in packs and recommends delaying further missions.
Cover under pressure
The finding increases the danger to the whole crew, but Heath must continue protecting his identity. His useful scientific explanation also brings him closer to the truth Benedict wants to control.
The Agent Is Silenced

The Agent Is Silenced
Suspicion detected
Benedict questions Heath about Devil’s Purgatory and reads his physical response. Heath denies knowing the location, but Benedict recognizes that the scientist’s cover may be compromised.
Evidence destroyed
Heath is killed and his body is concealed inside a UNIS barrel. The act removes an intelligence source and turns the ship’s security system into a means of hiding murder.
A Retrieval Plan Underway

A Retrieval Plan Underway
An urgent objective
CIA representatives and Masao discuss getting Terry and their agent off the ship before the Navy intervenes. They fear Benedict may use the remaining captives as hostages.
Institutions arrive late
The plan depends on timing, yet the Benthos is already collapsing and the people on board are in immediate danger. The intelligence operation’s careful strategy cannot fully account for the crisis it helped create.
