The man who made husbands jealous

the long version

Lysander Hawkley has a knack for trying to help the helpless, even if the helpless is a bored housewife. After his father refuses to lend him any money, his friend, Ferdie, comes up with a scheme to make money out of his womanizing: to help wives make their wandering husbands jealous. The plan, in theory, is simple: to make bored husbands realise why they had fallen in love with their wives in the first place. - from wikipedia
