Book Summary

In this provocative mystery from beloved crime writer Denise Mina, new evidence in an old murder case forces one woman to make an impossible choice.

What will it take to tell the truth when your life depends on a lie?

A year ago, a father and his fiancée were brutally murdered in their opulent London townhouse, sparking the most high-profile murder investigation in recent history. Blood spatter expert Doctor Claudia O'Sheil's evidence put the killer behind bars—or so everyone believes. But since the trial, Claudia's learned a horrific truth: her evidence and her testimony were wrong. And someone she knows made sure of it.

Now, as she takes the stage to give a career-defining speech before London's elite, Claudia faces a devastating choice. Protect her children and her career with her continued complicity, or blow the whole conspiracy apart and reveal the truth: not only is the real murderer still out there, but they're in the audience.

As Claudia steps toward the microphone, she revisits that fateful night. What really happened? And what will Claudia say?

18:38

Professor Claudia Atkins O'Sheil, MBE, and Lord Philip Ardmore were taking the back stairs at the Royal College of Forensic Scientists in Regent's Park, heading down to the distant rumble of a party in the open courtyard.

Even here, in a little-used service area, the new building was elegant and understated. A handrail of pale ash spiralled seamlessly down from the third floor. A soft light from skylights tucked into the eaves made the concrete walls look like grey suede in the late January gloom.

In just twenty minutes Claudia was due on stage in front of an auspicious audience, being filmed and recorded as she gave a career-defining speech about her most famous criminal case. She would outline the facts of the murders at Chester Terrace and the subsequent investigation, explain how her scientific evidence had secured the conviction of a vicious murderer.

But Claudia was not going to give that speech. She was going to tell the truth tonight. It would ruin her life but she had to ...

But what is the truth, and why is it so dangerous? Neither question is answered before the book jumps back in time to one year prior, the night of the murder in question. The narrative alternates between present day, just before Claudia's speech, and the past year in which Claudia works to solve the case. It's not a unique framework, but it is successfully employed here, creating a frantic pace that complements Claudia's scattered emotions...continued

Media Reviews

Daily Mail (UK)
As the tension mounts, the reader is kept guessing… The final denouement is a real cracker… Added to the fiendishly clever plot, Searle's writing is both drily amusing and elegantly crafted.

Financial Times (UK)
Intelligent as ever, Mina judiciously orchestrates suspense and anatomises issues of class—and even the nature of truth.

The Guardian (UK)
Claudia's attempts to decode a privileged world as she wrestles with her conscience make this suspenseful study of complicity a stand-out read.

The Scotsman (UK)
Part of what makes Mina such an interesting writer is that the science is a background to the moral and ethical questions she is posing, not an end in itself... . I would not call Mina a crusading writer, but there is a feeling that the topics she chooses are not random, but serious and urgent.

Booklist
Mina will keep readers in suspense as she weaves a complex web of personal and professional relationships with gruesome crime scene details and high-stakes life choices. Mystery fans will love this.

Kirkus Reviews (starred review)
A moment of triumph turns into terror in this dark thriller…Mina has long been adept at suspenseful pacing and at creating flawed but engaging characters, and here she paints Claudia as something of an anthropologist—a Glasgow native, she's constantly trying to interpret the codes and hierarchies of the English upper classes. As her search for the killer intensifies, it both expands into other dark doings and draws alarmingly close to home. A shocking but satisfying ending caps off this taut tale of murder among the privileged.

Publishers Weekly (starred review)
Outstanding... . Mina builds nerve-shredding suspense.

Beyond the Book



Bloodstain Pattern Analysis and Its Problematic Role in Forensic Science

A bloodstain pattern on a wall The protagonist of The Good Liar is a forensic scientist who has developed the Blood Spatter Probability Scale (BSPS), a fictional modeling system that uses blood spatter information from a crime scene to create a 3D model reconstruction of the events. Although bloodstain pattern analysis has been used to help solve real crimes for over a century, recent studies have discovered that many factors can influence the analysis of bloodstain patterns and create inconsistencies that could result in false convictions, as happens with the BSPS in The Good Liar.

Bloodstain pattern (BSP) analysis is the examination of the location, size, shape, and distribution of bloodstains at a crime scene. When these factors are analyzed in the context of ...
