Dark, engrossing and brimming with compelling characters – none more so than Guy Pearce as the titular private detective – Jack Irish seems to wrap- up too quickly. At a short and sharp six instalments, season two concludes tonight. In an action- packed finale, it begins with Jack putting his body on the line once again – and it won’t be the last time. When Jack discovers Kendra’s ( Anna Samson) hideout in the side of a cliff containing scientific research and video diaries, he’s suddenly knocked unconscious. When he wakes up, the evidence is gone.
