When a missing teenage girl is found dead in a parking lot, her throat slashed, it's only the beginning. Their discovery leads police directly to the bodies of two young immigrants killed in their run down apartment. The next morning three more men are found dead in the street nearby.

Welcome to summer in the city.

None of it makes any sense. But as Minneapolis Police Department homicide detectives Magozzi and Rolseath struggle to establish what's happened, they realise that the deaths may not be as random as they first appear. Nor, it seems, were they simply an isolated, freak twenty-four hours of violence in the Twin Cities.

As the killings continue, Magozzi and Rolseath turn to maverick computer analyst Grace McBride for help. But Grace's contribution to the investigation depends on her staying alive long enough to provide it.

And as the evidence mounts, piece by piece, it reveals terrifying intent. Ultimately, it forces the two detectives to make a dreadful choice: down which path does the lesser of two evils lie . . .

Two Evils offers all the knife-edge plotting, rich characterisation and crackling dialogue PJ Tracy fans have come to expect from a thriller writer at the top of their game.
