Colter is hired by Gavin Russo (Robert Moloney) to find his daughter Laura (Paolina van Kleef). Officially she died three years ago but Gavin swears he can see her in a photo from a couple of weeks ago. And Gavin may be right.

The mystery comes to the fore in this episode of Tracker and it’s a doozy. The show touches on the massive audience for paranormal investigation shows and combines that with a familial mystery and the consequences of it. Sharon Lee Watson’s clever script never really plays with the idea the supernatural is real, or not real, but rather approaches it the same way Colter does. Something to be understood in order to close the case.

That refreshing pragmatism gives Moloney and Diana Maria Riva especially a chance to shine in two of the supporting roles. Moloney’s grieving dad is an open wound of a man whose total emotional openness gives the episode its drive. But its heart is in Riva’s exhausted, troubled Detective Brock. Tracker is always at its best when it avoids fake adversarial relationships and Brock is onboard with Colter instantly. She’s open about the case, the cost it exacted on everyone and is engaged, motivated and damaged, It’s a great character, joining the legion of supporting players you’d be happy to see again and another great turn from Riva who you may recognise from shows like Dead Like Me or The West Wing.

Jon Huertas, a veteran of Castle and Generation Kill on the other side of the camera and a This is Us cast mate of Hartley’s, directs with some real style too. There’s a found footage sequence that’s central to the case and a couple of nicely haunted moment that never go OTT. Unsurprisingly though, Huertas is an actor’s director and he gives his whole cast plenty of room of shine. They do, as does the script.

Verdict: Another rock solid episode, a very good mystery and a great supporting cast. Tracker really is on a roll now. 9/10
