Some contracts expire. Others are written in blood.

When a high-profile whistleblower is assassinated moments before testifying about colonial-era atrocities, the only clue is a calling card left on the body: a wax seal impression showing a crown pierced by a dagger.

The same symbol appears in the margin of a 150-year-old contract discovered during routine digitization of colonial archives—a document authorizing a secretive military unit called "The Crown's Daggers" to operate beyond all laws and oversight.

Their mission: eliminate threats to Empire "by any means necessary, in perpetuity."

Their payment: bloodline privileges extending to all descendants, for as long as the Crown endures.

The contract was never officially terminated.

Now, a modern paramilitary force composed of direct descendants of these imperial enforcers is systematically eliminating anyone exposing historical crimes—operating with military precision, unlimited resources, and high-level clearance codes that shouldn't still work.

Plunged into a shadow war against killers who believe they're fulfilling ancestral duty, the team faces their deadliest adversaries yet:

Inaya infiltrates an exclusive private military company recruiting exclusively from certain family lineages, where she discovers training exercises specifically designed around eliminating people with her team's exact skill sets.

Sania races to identify potential targets on the mercenaries' kill list, only to find her own family name among them—forcing her to warn relatives who never knew the dangerous legacy of her agency work.

Adisa tracks the group's financial backers to a network of aristocrats and business leaders desperately protecting family reputations built on colonial wealth, putting her on a collision course with the mercenaries' most lethal field commander—who operates with the precision of someone who's studied her every move.

As governments disavow knowledge and the agency itself issues stand-down orders, the women uncover the horrifying truth: the contracts were designed to activate in precisely this historical moment—when colonial powers fear being held accountable for past crimes.

They're not just facing mercenaries. They're facing a legal mechanism created by empire to protect itself—even from the grave.

Some debts can never be repaid. Some contracts can never be broken.

CRIMSON CONTRACTS delivers military-grade action and relentless suspense in a high-stakes thriller where historical injustice meets modern-day black ops. For fans of TOM CLANCY, VINCE FLYNN, and JACK REACHER who demand intelligent heroines facing impossible odds.

Honor may be their weakness. Blood oaths may be their strength. But underestimating these three women will be their final mistake.
