The Pennine Way Killings (Michael McKenna #4)

Previously published as Unsafe Convictions.

Two years ago, Trisha Stanton Smith was burned alive in her own home. Her ex-husband, Piers, was convicted, but now the courts suspect his innocence. . .

The case has been reopened, and DCI Michael McKenna has been assigned to investigate. He’s pulled into the isolated town of Haughton in the Pennines, a place far from his usual stomping grounds.

As McKenna digs deeper, he uncovers unsettling truths: key evidence was overlooked, witnesses ignored, and the town’s powerful residents played a major role in the wrongful conviction. With each lead, McKenna traces a trail of corruption that runs deeper than he imagined.

But the case isn’t McKenna’s only challenge. Recently promoted, he faces scrutiny from colleagues questioning his ability to handle high-profile cases, and the pressure to prove himself is mounting.

The investigation takes a dark turn when another death occurs, eerily linked to the case. McKenna is forced to confront his own past — a failed case years ago that cost him a colleague.

With his past catching up to him and the stakes higher than ever, McKenna must crack the case before a killer escapes justice.
