A young Parisian lawyer is found murdered, burned alive with a flaming tyre around his neck.
For Lola Jost, retired police commissioner, the killer's methods are all too familiar. Her beloved assistant Toussaint Kidjo was dispatched in the same way five years before. Convinced of a connection, and aided by her loyal sidekick Ingrid Diesel, Lola reopens the Kidjo investigation on the sly.
But the murdered lawyer turns out to be the protégé of a shadowy fixer known as "Mister Africa", who is heavily involved in the arms trade. And the official investigation becomes mired in a power struggle between the Paris police and a newly formed national intelligence agency.
Lola and Ingrid have earned their reputation as amateur super sleuths who get the job done when the police can't
- or won't. But the high-stakes world of international arms dealing plays by its own brutal rules, and this case could
prove too hot for them to handle . . .
