Treason at Lisson Grove

In late Victorian London, a dying informant takes a conspiracy's secrets to the grave before Thomas Pitt can reach him—and the chain of events that follows stretches from the fog-soaked streets of the city to the coast of France, pulling Pitt further from home just as the ground shifts dangerously beneath everyone he trusts. Back in London, his wife Charlotte and their ally Victor Narraway face a different kind of threat: one rooted in betrayal, reputation, and the quiet violence of political manipulation. Anne Perry understands that the deepest suspense isn't about who holds the knife but about who holds the power—and how quickly loyalty can be weaponized.

What makes this installment particularly satisfying is how Perry expands the series beyond Pitt's familiar professional world, giving Charlotte genuine agency in a high-stakes situation that demands her intelligence rather than her patience. The dual-track structure keeps tension taut without feeling mechanical, and Perry's prose remains precisely observed—period detail worn lightly, characters shaped by what they choose not to say. After twenty-six books, this series still knows how to surprise.
