Madam Lydia

Victorian London. Lydia, now a fully-fledged working girl, is in great demand, both at the Silken Web bordello and for lucrative ''private engagements.'' She also finds herself becoming a mentor to her alluring younger colleagues, Kate and Emily, although her relationship with them is as intimate as it is sisterly.

As Lydia assists an increasingly wealthy and hedonistic clientele with the realisation of its wildest fantasies, she begins to enjoy the exhibitionism and ritual role-play involved as much as the physical pleasures she has always relished. Then Lady Amanda - a regular client with a taste for lesbianism and depilation - introduces Lydia to a clandestine society which tests her sexuality to its very limits.

This is the fourth book in Philippa Masters'' Lydia series.
