Book excerpt: How do you stop a killer who’s already behind bars? Sacramento Police Detectives John Penley and Paula Newberry are enlisted to investigate a case involving the trafficking of stolen street drugs. But they quickly find it’s more difficult than they first imagined when the crime is being committed by a group of corrupt cops undermining the system. That’s not the only wrench thrown at Penley and Newberry, however, as Sherman, the leader of the group, is orchestrating murders against those who testified against him. He turns the lens onto Newberry, who begins to receive blame and as the political pressure mounts, it’s clear someone has to pay for the crimes. And it comes down to Newberry or Sherman. With a plot full of twisty, hairpin runs and heart-pounding action, Jim L’Etoile’s Bury the Past is a riveting follow-up to the first in the Detective Penley mysteries, At What Cost.
