The vintage plot concerns a Gainsborough miniature, a mouldering country house, an overweight solicitor, a fortune-hunter, a butler who isn"t a butler, an American corporate lawyer and his kleptomaniac sister; but the heart of the story - in every sense - concerns Jerry West and his determined pursuit of air hostess Jane Hunnicutt, the eponymous Girl in Blue. When Jane unexpectedly becomes a millionairess, Jerry despairs of wooing her, but the sun never goes behind a cloud for long in Wodehouse: Jerry gets his Jane in the end, but only after a series of trials which raise the comic stakes to the author"s highest level.
