Query: Shallow and poorly researched

I love murder mysteries. If you do too, skip this one. The plot was painfully predictable. The supposed fatal illness "Nigli's apastic anemia" that the main character has does not exist. I'm an RN and have worked with bone marrow transplant patients for 23 years. To have the chief detective of a serial murder investigation be newly diagnosed with a fatal hematologic illness, not tell her superiors and continue in her position is preposterous and would be unethical in the real world. That this condition is "treated" (and evenually "cured"!) with blood transfusions is ridiculous.I had similar reactions to the woman's group. No depth, unrealistic.
