Of course, all families, high born and low have secrets. Confidential conditions of mind or body. Black sheep. Skeletons in cupboards. Unmentionable uncles. Naughty nephews... aunties who aren't... conventional. More often than not it boils down to something - sexual.

This episode is about the keeping and uncovering of family secrets. In a way it unlocks all the secrets in all our episodes.

Many Victorians, especially the more successful ones, feared shame. In a way this fear was something quite new. A new and growing newspaper industry was keen to amplify that shame. And a new middle class, desperate to cling to its new-found monied status, felt threatened. And, new theories about heredity, coming later in the century, meant that (perish the thought!) shamefulness could be passed on – like red hair or big feet - from generation to generation.

Step right up, step right up and don’t be shy - welcome to Victorian Secrets, and the secrets of... The Freak Show. The secrets of enormously fat men and bearded ladies, the secrets of exotic women with enticingly large buttocks, the secrets of Siamese Twins and dwarf families and, in particular, the secrets of our own, our very own Aztec Children, seen by half a million people on the European continent before they publicly revealed their own, personal, extraordinary secret.

We’ll go backstage to hear the terrible secrets of the freaks themselves, we’ll lift the lace curtains of Buckingham Palace, where our own Queen, god bless her, took tea with the tiny, the towering and the terribly formed.

This episode will penetrate some of the secrets of Victorian sexuality, public and private and will challenge some deeply held misconceptions.

We tend to think of the Victorians as dyed in the wool prudes, and we have latched onto the idea that the Victorians felt their values of self-discipline, temperance and hard work were threatened by the temptations of the flesh. This episode will show in enjoyable detail that ordinary Victorians’ attitudes to sex was for the most part enthusiastic, unembarrassed and surprisingly well informed. Apart, that is, from one secret sexual practice that was loathed, feared and tragically misunderstood.
