The team of Det. Supt. Michael Walker, DI North, and DCI Connor follows each case from crime committed, through the pursuit of justice, to the law courts where the efforts of the force will be tested--sometimes to the breaking point.
Metroploitan Police Commander Jack Delany and his wife Honor, a magistrate ,are murdered in their home and valuables are stolen in what initially seems to have been a burglary that went wrong.
Despite an apparently water-tight alibi, there is something about the twins' behaviour that makes Walker uneasy, particularly as the dominant Michael seems to be controlling his asthmatic brother.
