Some secrets are too dangerous to tell.

When gunshots shatter a quiet summer night on Mount Macedon, Detective Sergeant Zoe Mayer and her steadfast service dog Harry are first to the summit at dawn. There, they uncover what appears to be a grim murder-suicide: disgraced financier Piers Johnson and his lawyer Antony Peterson, both shot dead, a pistol lying between them.

But something feels wrong. The story doesn’t fit, and neither do the people surrounding it. Suspects abound—each with secrets, each with something to hide. As the pressure mounts to deliver answers, Zoe’s gut tells her the truth is far more twisted. Then Peterson’s teenage daughter, Sarah, vanishes without a trace.

In The Good Dog, Zoe faces her most harrowing case yet—a chilling conspiracy driven by greed, lies, and cold-blooded violence. With time running out and danger closing in, she knows that uncovering the truth may cost her everything. And once again, it’s Harry who might just be the key to solving it all.
