In Rachel Knight, author and OJ Simpson prosecutor Marcia Clark has created a feisty heroine with class and style - a terrific character for a heart-thumping thriller series set in LA.

When Deputy District Attorney Rachel Knight's journey home is interrupted by screaming sirens, she decides to follow them.

But what she finds when she arrives at a sleazy LA motel shatters her world: her trusted colleague Jake lies dead beside the body of a teenage male prostitute.

The police say murder/suicide. Rachel's gut says different.

Her search for proof will take her through the dark and tangled city, from its wealthy suburbs to its violent heart.

And a truth so dangerous it could kill her.
