What will it take to tell the truth when your life depends on a lie? This is the question a blood spatter expert grapples with when she realises she sent the wrong person to prison. The 20th novel from NYT bestseller and Costa-shortlisted crime writer Denise Mina, for fans of Tana French and Elly Griffiths.

** FROM THE NY TIMES and Costa shortlisted author, comes a NEW standalone thriller**

The truth might set her free ... but will it be the death of her?

When blood spatter expert Claudia O'Shiel finds herself on stage to talk about the most famous criminal case in recent history, she has a choice to make- explain how her evidence put away the man responsible for the brutal double murder? Or tell them the truth - that the real killer is still out there, and if she tries to expose this conspiracy, it won't just be her life on the line.

A taut, intelligent suspense novel for fans of Val McDermid, Elly Griffiths and Tana French, The Good Liar is about power, class, and the lengths we're willing to go for family.
