The Missing Witness (Quinn & Costa #5)

When a key witness goes missing, Quinn and Costa must find her before a killer silences her for good…

Detective Kara Quinn is back in Los Angeles to testify against a notorious human trafficker, finally moving past the case that upended her life. But when the accused is shot by a masked man in broad daylight, the chaotic scene of the crime turns up few reliable bystanders. And one witness—a whistleblower who might be the key to everything—has disappeared.

After the prosecuting DDA is stabbed to death, it’s clear that anyone who knows too much about the investigation is in danger, and tracking down the witness becomes a matter of life or death. With government corruption running rampant and someone on the inside trying to pin anything they can on Kara, she trusts nobody except FBI special agent Matt Costa and a handful of allies.

But when explosive secrets begin to surface within the LAPD and FBI, Kara questions everything she thought she knew about the case, her colleagues and the life she left behind months ago.

Now Quinn and Costa must race to find the missing witness and get to the bottom of the avalanche of conspiracies that has rocked LA to its core…before it's too late.
