Leila Mercer is a burned former operative now working Tehran as a regional analyst cover, and in Faltering Trust she gets pulled back into the city’s internal intelligence war when a message arrives early, a location is falsified, and local counterintelligence turns a compromised apparatus against her. Riding the southern ring in a battered Peugeot and reading through an untraceable messaging app she no longer fully trusts, Leila realizes the crackdown is not coming from outside Iran at all: it is coming from within the system that once used her.

With her agency status ostracized but still useful enough to sustain covert action, Leila has to build a reliable extraction plan while dodging local intelligence traps, a year-long disinformation campaign, and a mole hunt inside her own network. The asset’s next drop is scheduled within twenty-four hours, and the hostile side is using that deadline as bait. If she moves on the wrong coordinate, she exposes the asset, the family member who wants to defect, and the thin trail of contacts still keeping her alive.

Leila’s fatal flaw is personal as much as operational: her emotional pull toward the asset keeps overriding her objectivity, even as the handler she half-trusts and the rival operative shadowing the extraction make every choice more dangerous. She lives by one rule — never abandon a source who trusted you, regardless of the cost — but that code now threatens her cover identity, her credibility, and the last clean route out of Tehran. The cost is to keep a false security alive long enough to save the source’s family while Tehran’s counterintelligence tightens around Leila’s own threadbare affiliation.
