Maggie O’Malley works in the pharmaceutical industry, which gives author Kathleen Valenti a rich setting for murder plots tied to drug development, corporate cover-ups, and the ethics of medicine. Protocol, the first book, establishes Maggie as someone who stumbles into danger through her work rather than seeking it out.

The series has a consistent tone across its three books – mystery with dark humor, a protagonist who is smart but not infallible, and plots that take the pharmaceutical setting seriously rather than using it as mere backdrop. 39 Winks and As Directed carry the story forward while introducing new complications in Maggie’s personal and professional life.

For readers who enjoy mystery series with a grounded protagonist and a specific professional world as the stage, the Maggie O’Malley books offer three tightly plotted stories that can be enjoyed as a complete run.
