Dark Chemistry — Catherine Lee

Everyone is entitled to a voice, but has a protest group turned to murder to make themselves heard?

A fatal stabbing in a local park appears to be a mugging gone wrong â€" but Detective Charlie Cooper suspects there's more to this murder than meets the eye. The victim worked at a local pharmaceutical plant, where protesters against the company's manufacture of vaccines are becoming increasingly vocal. The victim was the CEO's nephew, and soon a clear message is sent â€" stop making vaccines, or more blood will be shed.

Lab Technician Leo McCarthy loves his job at Lighthouse Pharmaceuticals. Processes and procedures, scientific testing, black and white â€" all things Leo's difficult mind can understand. But when his friend is murdered, Leo's world is thrown into a type of chaos he thought was long behind him.

A police procedural tale that tackles one of society's most dividing issues, Dark Chemistry is the fourth in Catherine Lee's page-turning Dark Series. Cooper and Quinn are back in another rollercoaster mystery, and this time murder isn't the only thing rocking Cooper's world.
