Reggie Perrin is a sales executive on the edge - an average man finding it increasingly difficult to put up with the monotony of life, a disappointing marriage and ten years of the daily commute and the office grind. The head of disposable razors at male-grooming firm Groomtech, he gradually begins to crack. At first he rebels only mentally, in the form of increasingly surreal flights of fancy. But slowly, he begins telling his wife, his boss and his fellow commuters what he really thinks. As well as, most dangerously of all, his new colleague - Jasmine Strauss, the beautiful head of balms and lubricants, with whom Reggie becomes besotted.
