The new jaw-dropping, twisty thriller from Sunday Times bestselling Ruth Mancini.

You were only seven years old when you witnessed your mother's murder.

Although you did not see her attacker clearly, you are pretty sure who it was.

Thanks to you, he went to prison for twenty years.

Now he's out.

And you are no longer certain that the man you identified that terrifying evening really was the killer.

But if it wasn’t him, who was the stranger on the stairs?

And can he now be coming for you?

Inspired by a shocking real-life case, a gripping psychological thriller by a criminal defence lawyer who has seen it all.

Praise for The Stranger on the Stairs

Brilliant. My favourite Ruth Mancini yet. A taut, haunting and thought-provoking story of fractured memories, complex relationships and coverups. Kept me guessing (and biting my nails) throughout.

Anna Mazzola

Wow! Everything you’d expect from the brilliant Ruth Mancini – a propulsive, heart-thumping read, complex characters you really care about, multiple layers of thought-provoking insights, taut plotting, and an absolutely nail-shredding finish. Fantastic! If Ruth Mancini’s writing it, I’m reading it!

Gill Perdue

Ruth Mancini writes thrillers with the certainty of someone who’s seen the law in action and knows exactly how to unpick it. Brilliantly smart, unsettlingly human and impossible to put down.
