The Lost Treasure of the Templars Books in Order

The Lost Treasure of the Templars series follows antiquarian bookseller Robin Jessop and encryption expert David Mallory as they stumble into the unfinished business of the Knights Templar. Instead of chasing a single chest of gold, they are hunting paper, parchments and secrets that powerful people still care about.

It all begins in The Lost Treasure of the Templars when Robin buys a curious medieval volume for her small shop on the English coast. The object turns out not to be a book at all but a disguised safe, and inside lies one rolled parchment written in an elaborate code. That scrap of writing is enough to mark her as a target and to suggest that the Templars left more behind than ruins and legends.

To make sense of the cipher she turns to David Mallory, a gifted mathematician who earns his living breaking complex codes. Their partnership is uneasy at first, mixing Robin's instinct for old manuscripts and book trade gossip with Mallory's cool, analytical approach to patterns and probabilities. Over time they shift from reluctant allies to friends who trust each other with their lives.

They quickly discover that the so called treasure is really information.

Across the three books the clues lead them through churches, archives and hidden strongrooms as they piece together how the Templars managed land, money and favors for nobles across Europe. The Templar Archive makes it clear that records of who owned what, who owed whom and which families kept which promises can be more explosive than any hoard of coins. By The Templar Brotherhood Jessop and Mallory are moving through the inner circles of old societies, where people will happily trade blood to keep their ancestors' deals out of the light.

The series leans less on gunfights than on tension and pursuit. Robin and David spend as much time poring over floor plans, old maps and marginal notes as they do running from hired muscle, but the danger is constant. Becker uses brief trips back to the fourteenth century to show how the original Templars were betrayed and scattered, then cuts back to the present where their paperwork still has teeth.

If you are drawn to stories about hidden archives, forgotten banking systems and the idea that a single document can topple an empire, this series is designed for you. It reads like a long, intricate treasure hunt in which the true prize is knowledge, and the cost of finding it may be very high.
