It was the fashion during Regency to hire a house for the Season in Mayfair-the heart of London's fashionable West End-at a disproportionately high rent for sometimes very inferior accommodation. So why is it that Number 67 Clarges Street, a town house complete with staff, remains vacant season after season? The home of numerous families in the past to whom ill luck-even death-has befallen, Number 67 has been damned as unlucky. In the Miser of Mayfair, salvation seems to come at last in the form of a Mr. Roderick Sinclair, who has confirmed his intentions to let the house for the Season. The staff are overjoyed-until they find that Mr. Sinclair is a terrible miser and is planning no parties. Furthermore, his ward, Fiona, seems not to have a bright idea in her head. Only Rainbird, the clever and elegant butler of Number 67, plots with Fiona to bewitch, bedazzle, and confuse the earl into seeing things their way.
