S11·E19 Love Hurts

Sergeant Merton is dating Vivienne Keen, but the morning after a date she accuses him of stealing her purse. Merton of course denies the allegation and is suspended pending investigation, but things do not look to good for him when the purse is found in his apartment. Furthermore a similar allegation was made against him ten years earlier, but the case was dropped. PC Bradley still thinks his superior is innocent and begins his own, private investigation at the risk of being suspended himself. Bernie Scripps is acting strangely. He has seen Dr. Summerbee a lot recently and Vernon is afraid he suffers from a serious depression.
