Thomas Pitt arrives at a devastating bombing in Lancaster Gate to find two policemen dead and three more gravely wounded.
London's anarchists are blamed, but as Pitt and Inspector Tellman investigate they find it looks increasingly like a personal vendetta against those particular men. Did they lie about a drugs raid that went fatally wrong, and let an innocent man hang?
The idea of police dishonesty cuts Tellman to the quick - he joined the force to protect society, not exploit it. But he must uncover the truth, however much he wants to resist the signs of blackmail and corruption. With the threat of further bombings, and their superiors pushing for a quick resolution, Pitt and Tellman find their every move scrutinised, and their own lives suddenly at risk...
Treachery at Lancaster Gate is the exceptional new historical thriller from the master of Victorian crime.
