Burning the Books (S01E09)

When a young car thief discovers a briefcase, Det. Insp. Galloway believes he’s finally on the trail of Sun Hill’s own 'Arthur Daley.' However, car troubles prevent him from interviewing his main suspect. Later, after a fire at a warehouse that is meant to assure Galloway that the porn magazines were incinerated, he and his team return to the station only to witness the van transporting the magazines departing from the back entrance, where it had been parked for a full day.
