They met at the Chelsea Arts Ball: he went as a paper parcel, and she as a Spanish dancer. Harry Gibson and Miss Diver fell deeply in love…

But when Mr Gibson decides he’ll have to marry the hopelessly unprepossessing daughter of his colleague in order to save his ailing business, Miss Diver is cut off without a penny. She’s forced in turn to take in a lodger, Mr Philips, who mistakenly takes Miss Diver for a much richer woman than she is…

Watching over them all is Miss Diver’s niece Martha, a clumpy, unappealing child of a certain artistic genius.
