Kathleen Valenti writes mystery fiction with a protagonist who brings a scientific background to crime-solving. Maggie O’Malley is a pharmaceutical researcher, and that professional setting shapes both the plots and the way Maggie approaches the problems she encounters. The series has the pacing and dark humor of cozy mystery alongside more serious thriller elements.

The series launched in 2017 with Protocol and added two more books over the following two years. Valenti uses her background in the pharmaceutical industry to give the series an air of authenticity, particularly around the corporate and ethical dimensions of drug development that run through the plots.

Readers who enjoy amateur sleuth fiction with a protagonist in a specialist profession will find the Maggie O’Malley series a good fit. The books work well read in order, as recurring characters and relationships develop across the trilogy.
