Known Essex criminal Jason Simons is found murdered in too similar a way to Honeywell to be a coincidence - beaten, shot and dumped. But as anomalies in his post mortem start to stack up, it is discovered that Simons was not what he seems.
The team find traces of drugs on Simons's penknife that point to a major importation, but his bereaved girlfriend Tess does not seem to know anything about it. Suspicion turns back to Dean Fallon, but a discovery in his medical records and the death of the Fallon family lawyer, Ben Osrin, takes the investigation in an unexpected new direction.
