Smelling of Roses (S05E08)

Henry finds himself perplexed when he suddenly loses his ability to smell. Meanwhile, Fisher is fixated on apprehending tyre exporter Peter Watson, leading Henry to suspect that Fisher, who is on the brink of divorcing his wife, might be involved with Mrs. Watson. However, she has uncovered her husband's embezzlement of her charity funds and is using Fisher to ensnare him. Feeling manipulated by Fisher to pursue Watson, Henry resigns from the police force and miraculously regains his sense of smell. With Gary declining a job offer at another kitchen, Henry and his team have ample reason to celebrate the ongoing success of Pie in the Sky.
