Ashes to Ashes by Mary Monica Pulver
A body is found in “Crazy Dave” Wagner’s appliance store after the store is destroyed by a fire. Detective Peter Brichter is called in because local organized crime is thought to be involved. Brichter consults arson investigator Captain Isaac (Zak) Kader, and other officers in the police department, but no matter how many suspects they interview, they seem no closer to solving the case. Meanwhile, at home, Kori Brichter struggles with the right timing to tell Peter that she’s pregnant, after they agreed they would not have children.
