I Know Her Voice by C.M. Vane
I KNOW HER VOICE by C.M. Vane begins at 2:17 a.m., when a mother answers her husband’s phone and hears her daughter crying:
“Mum, I think I’ve killed Dad.”
By sunrise, the husband is dead and the daughter is in police custody.
Then the daughter says she never made the call.
The phone records prove the call happened. There is no recording of what was said. The mother is absolutely certain of one thing: she knows her daughter’s voice.
As the police investigation begins to uncover secrets Daniel kept from the people closest to him, Claire is forced to question not only what happened that night, but how well she really knows her own family.
Because if Sophie is telling the truth, somebody wanted Claire to hear that confession.
And if she is lying, Claire may be the person who helps prove her own daughter guilty.
A psychological thriller about family, trust, memory and the frightening distance between what we know and what we can prove.

AUTHOR INTERVIEW WITH C. M. VANE
Can you introduce I Know Her Voice to readers?
I Know Her Voice is a British psychological thriller built around a very simple but unsettling problem.
At 2:17 in the morning, Claire Bennett sees her husband Daniel’s name on her phone but hears her adult daughter Sophie on the other end. Sophie is upset and tells her, “Mum, I think I’ve killed Dad.”
By the following morning, Daniel is dead and Sophie is being questioned by the police.
Then Sophie tells Claire she never made the call.
The phone records prove that the call happened, but there is no recording of the conversation. Claire is certain she heard her daughter, because Sophie’s is a voice she has known for more than twenty years.
The mystery really begins with that contradiction.
Where did the idea for the novel come from?
I became interested in the difference between knowing something and being able to prove it.
There are certain voices most of us would say we could recognise instantly. A child, a parent, a partner or somebody we have known for years. We don’t stop to analyse the voice. We simply know who is speaking.
I wondered what would happen if somebody’s entire understanding of an event depended on that kind of certainty.
Claire has absolutely no doubt that she heard Sophie on the phone. Sophie is equally certain that she never made the call. I liked the idea of putting a mother between those two apparently impossible truths and seeing what happened when evidence, memory and family loyalty began pulling her in different directions.
Is this primarily a murder mystery or a family story?
Hopefully it works as both.
There is obviously a mystery at the centre of the book, but I was particularly interested in what that mystery does to the Bennett family.
Claire wants to protect Sophie, but Claire is also the person whose account of the phone call makes Sophie look suspicious. That creates a difficult situation because the person Sophie most needs to believe her is also the person most certain that she heard her speak.
The investigation gradually uncovers things Daniel had kept from the people closest to him, so Claire also has to reconsider what she thought she knew about her husband and her marriage.
For me, the suspense comes as much from those changing relationships as it does from trying to solve what happened.
What makes Claire an interesting protagonist to write?
Claire isn’t a detective and she doesn’t suddenly become one.
She is an ordinary person dropped into a situation where something she regards as completely reliable, her ability to recognise her own daughter’s voice, becomes crucial.
She is also stubborn, which is both a strength and a weakness. She refuses to pretend she did not hear what she heard simply because accepting Sophie’s version would be emotionally easier.
At the same time, she loves her daughter. The tension between those two things drives a lot of the story.
What do you hope readers will be thinking about while they read?
Mostly I hope they keep changing their minds.
I wanted the book to keep asking a deceptively straightforward question: who do you believe?
Do you believe the person you love? Do you believe the evidence? Do you believe your own memory? And what happens when those things no longer agree with one another?
There are clues throughout the story, so I hope readers enjoy looking back afterwards and seeing how pieces they interpreted one way earlier in the book take on a different meaning later.
What sort of reader do you think will enjoy I Know Her Voice?
Readers who enjoy psychological thrillers built around family secrets, suspicion and a strong central mystery should feel at home with it.
It is particularly for people who like a thriller where the mystery isn’t just “who did it?” but also “who is telling the truth?” and “how certain can we really be?”
The story moves quickly, but the relationships between Claire, Sophie and Daniel are at the centre of everything.
