In COLD DAY IN JULY Dr. Reb O'Brien reencounters Marc Girard who left the town thirteen years ago vowing he'd never return. They are different people now, Reb the town doctor and Marc a New Orleans Architect. Even the attraction they feel for each other is different—this isn't puppy love anymore, far from it. But Marc didn't return to Toussaint looking for Reb, although curiosity made him hope he'd meet her again, he came because of the most recent unexpected and supposedly accidental death in town, that of singer, Bonnie Blue.
Reb has accepted the accidental death verdict. Marc believes this was a murder.
Reb is certain the dead woman was Bonnie Blue. Marc is convinced the victim was his missing sister, Amy.
His return raises fear among many business proprietors in Toussaint because Marc's mother, who also left the area, continues to own much of the commercial property in town. The tenants fear the Girards may be planning to sell out which would mean their reasonable rents could skyrocket.
Local suspicion of Marc doesn't help him get the answers he's looking for about the recent death. The town's protectiveness of Reb, and attempts to keep her away from Marc, add more obstacles. When Reb finally admits to him that she thinks she's in serious danger, and they are all but isolated together in a hunt for a killer, need turns to want, and to an obsession neither is willing to ignore.
