A cybersecurity executive is murdered. Was it a random shooting, or a targeted killing?

It’s up to Silas McKay, chief investigator for Discreet Corporate Security Services, to find out.

When Silas is asked to investigate the murder of Sherwood Fenton, he discovers there are already two suspects.

The widow believes the owner of a rival software company killed her husband . . .

She claims he threatened to get revenge on Sherwood during a heated argument.

The police believe Sherwood’s murder was a gang-related shooting . . .

The homicide detectives are focused on a teenager with a facial tattoo who was seen running from the scene.

Silas believes they’re both wrong . . .

He’s looking at a third suspect, someone who’s been hiding in plain sight.

As Silas works through the investigation, he’s also dealing with his budding romantic relationship with Ashley Davenport, the amusing—sometimes not so amusing—antics of his new puppy, and the ever-present conflicts between the eclectic members of his investigative staff.

When Silas finally identifies the real killer, he learns a second murder is being planned, and as he tries to protect the victim, he confronts the killer in a high-stakes encounter where the outcome is anything but certain.
