The unmissable thriller in the million-copy-selling Katie Maguire series.

On a quiet country road, a good man burns.

Justice Garrett Quinn should have been at a sentencing. He was one of the good ones, fighting for order in a lawless world. In a burned-out car, on the outskirts of Cork, DS Katie Maguire finds what's left of him.

But this is only the beginning. The judge's death sparks a gang war, catching civilians in the crossfire. As the city spirals deeper into violence, Ireland's most fearless detective must find the courage to fight for her hometown once again.

Katie Maguire is no stranger to sacrifice – but she has lost so much already. Facing new horrors each day, Katie must decide:

Can she do her duty when she has nothing left to give?

Perfect for fans of Peter James, CJ Tudor and Chris Carter, The Last Drop of Blood is part of the darkly original million-copy-bestselling DS Katie Maguire thriller series, which can be read in any order.
