The Midnight Choir by Gene Kerrigan
Sometimes, getting away with it is all that matters.
Dixie Peyton, widow of a petty criminal, is struggling to regain custody of her son. In desperation she seeks the help of controversial detective Harry Synnott, a man obsessed by his own interpretation of justice. But Synnott has other priorities. As he finds himself getting deeper into trouble, Dixie risks becoming a sacrifice on the altar of Synnott's career.
Meanwhile the police have arrested a blood-stained man. They seem to have chanced upon a murderer - now they need to find out who he killed. Ruthless gangland leader Lar Mackendrick is hunting an informer. And armed thief Joshua Boyce is about to rob a jeweller's shop. For all of them, as the pressure mounts and the choices become stark, getting away with it is all that matters.
