The whodunnit element is, perhaps, one of the lesser reasons for enjoying this series. The orgies and sadism add piquancy, especially given our erroneous view of a rigid Thirties morality, but the real fascination - and what will keep you waiting for the final part - lies in the relationships that drive the tale. Lizzie is married to Matt but carries a thing for John. John loves Matt but knows he could be happy with Lizzie, Matt loves Lizzie and John but has told John that his love had better not speak its name.
