A photograph does not lie.

At least, that is what someone wants the British government to believe.

When diplomat Lionel Atheling disappears during sensitive commercial negotiations in Brussels, the evidence against him seems devastating: a photograph places him inside an Antwerp warehouse with industrialist Thaddeus Ord, apparently conducting the very secret meeting that could destroy his reputation and compromise British interests.

But photographer Dinah Vesper sees what everyone else has missed.

The light is wrong. The reflections are impossible. And the photograph was not merely altered after printing—the deception was built into a newly manufactured negative, allowing the same false evidence to be reproduced again and again.

Together with aristocratic linguist and unofficial intelligence operative Verity Vesper, Dinah follows the photograph from Brussels salons to Antwerp warehouses and the workshops of Paris. What begins as the search for one missing diplomat becomes the discovery of something far more dangerous: a system capable of manufacturing meetings that never occurred, scandals that never happened, and evidence convincing enough to alter political decisions before anyone thinks to question it.

Yet the conspiracy is not the only uncertainty between the two Misses Vesper.

They share rooms. They share secrets. They share each other's beds.

Dinah believes that makes them lovers.

Verity believes they never agreed on what being lovers means.

Neither woman has lied—and that may be precisely the problem.

As forged evidence draws them toward an enemy willing to reshape truth for profit, Verity and Dinah must decide not only what can be trusted in a photograph, but what two women are entitled to assume about one another when desire has become intimacy and intimacy has begun to demand a name.

A Victorian sapphic espionage romance of photographic deception, political intrigue, complicated trust, and two women who refuse to let either danger or love simplify them.
