134. Love Me Love My Dog

McCann learns some hard truths about what it takes to be a sergeant as he and Stamp search for a troubled schizophrenic who has been harassing his neighbours. As they speak to the young man's grandmother, who appears to be the driving force behind his recent campaign, they discover his neighbours may have been responsible for a fire which burned down the man's flat six months ago. As they continue their search, McCann is devastated when they find a body in the local park.
