The first day of summer is the last day of a young accountant's life. Colin McHenry is out for his regular run when an SUV crosses into his path, crushing him. Within hours of the hit-skip, Cleveland Homicide Detective Jesus De La Cruz finds the vehicle in the owner's garage, who's on vacation three time zones away. The setup is obvious, but not the hand behind it. The suspects read like a list out of a textbook: the jilted fiancée, the jealous coworker, the overlooked subordinate, the dirty client.

His plate already full, Cruz is assigned to a "special project," a case needing to be solved quickly and quietly. Cleveland Water technicians are the targets of focused attacks. The crimes range from intimidation to assault. The locations swing between the east, west, and south sides of the city. This is definitely madness, but there is a method behind it.

The two cases are different and yet the same. Motives, opportunities, and alibis don't point in a single direction. In these mysteries, Cruz has to think laterally, yanking down the curtain to expose the master minding the strings.
