Dead in the Water (Police Scotland 1, Paperback)

She was meant to testify. Now she’s vanished.

When a key witness fails to appear in court, Acting DC Scott Cullen and DC Craig Hunter are sent to track her down. But what they find instead is a scene of death — two homeless women, both dead from a supposed overdose.

But something doesn’t add up.

The deeper they dig, the clearer it becomes: this wasn’t random. It’s part of something bigger — a criminal operation targeting the vulnerable, and another team of detectives keeping secrets of their own.

To stop the killings, Cullen and Hunter must find the witness before the killers do.
