Greenwell's Glory

A financial wizard in the city of London has just completed a billion pound deal. For rest and relaxation he travels to Ireland on a long promised fishing trip. On the riverbank, he encounters a little man wearing a cap who appears to have magical powers to such an extent that the Londoner perceives the little man to be a leprechaun but he is not! Before he returns to London he embarks on a singular plan to extract the little man's secret by plying him with whiskey and Guinness thereby revealing a bizarre tale of specimen brown trout and green silk knickers!
