In the first week of May 1782, a box at the Drury Lane Theatre was reserved at the request of Miss Scarlette of Henrietta Street.  This is remarkable in itself, given her reputation: boxes at the Theatre were generally the preserve of the particularly fashionable or royal.  The names attributed to her party include 'Doctor J', also of Henrietta Street; Miss Juliette Vierge, to whom he was said to be engaged; Mr Fitzgerald Kreiner (a German, apparently, rumoured to be a distant relative of the royal Hanoverians); and Miss Anji Kapoor.  When the party entered the box there was hissing from the crowds below, but this was nothing unusual.  The Theatre was a noisy place, and the bon ton liked to judge their standing in society by the reaction they were given from the cheap seats.  Scarlette would have been easy to recognise as one of the 'suspect' demi-reps, though she, of course, didn't even acknowledge the sound.  She was reported to have had a satisfied smile on her face as she took her seat.

Because so many of the accounts of Scarlette come from Lisa-Beth, it's easy to see this Procuress of Henrietta Street as a woman living in a world of her own.  But even apart from the great impact she obviously made on those around her, tales of her exploits are legion.  She was said to have bested the famous dandy highwayman and wencher 'Sixteen-String Jack' in a drinking contest shortly before his public execution, and to have disarmed him of his weapon one-handed after he took the defeat badly.  And she was just as formidable on the night of the Theatre visit.  Arriving by hackney cab outside, her party had been met by a group of prostitutes from south of the river who abused her friends and threatened her with violence, stating that she was bringing disrepute even to their kind.  According to one popular story, Scarlette responded to this by casually drawing a musket and pointing it at the leader of the women, saying: 'If it's blood you wish to see, then let it be on my hands.'

In fact, this story is apocryphal.  The truth about the encounter was stranger yet, as later events would show.  Scarlette's demeanour was one of perpetual calm, and she appeared amused by events around her no matter what the threat.  In this respect, she must have got on with the Doctor remarkably well.  She spent more time in his company than any other individual at the House, leading to (entirely untrue) rumours that they were having an affair; that his marriage to Juliette was part of some dastardly plot masterminded by Scarlette herself; even that the Doctor was some demonic reincarnation of Francis Dashwood, a rumour given weight by the fact that the founder of the Hellfire Club had died  (in suspicious circumstances, naturally) just weeks before the Doctor has arrived.

One night the Doctor and Scarlette spent the entire evening alone, drinking wine in the salon of the House.  Scarlette claimed that they lay together on the floor, staring up at the rafters in the ceiling, trying to see through the wood and into time itself.  This was punctuated by some giggling - even from the Doctor, it would appear - and the pair attempted to outdo each other with tales of their adventures, the Doctor claiming that he'd once been invited into the boudoir of Marie Antoinette, Scarlette claiming that she'd once ridden a woolly mammoth (still not believed entirely extinct) which had been a gift to George III from Catherine of Russia.  It was probably now that the Doctor made his notorious 'two hearts' claim, exactly the kind of story which would have been told by charlatans like Cagliostro in France.  When either the alcohol or the meditation caused them to be successful in their efforts to see through the ceiling, Scarlette fashioned a pair of crowns for them to wear out of dyed paper and declared them to be 'the King and Queen of All Time'.  The Doctor ostensibly stated that he was reluctant to become any kind of king, so Scarlette instead crowned herself the Queen and declared him to be her Physician in Ordinary.  (She jokingly said that she was still waiting for somebody truly special to be her Physician in Extraordinary.)

At the Theatre, many members of the party were evidently nervous at the crowd's reaction, particularly Mr Kreiner and Miss Kapoor.  They must have been taken aback by the audience, and probably put out by London society's habit of loudly talking through the performance about the latest scandals amongst the bon ton.  Drury Lane was a place in which one was seen, not a place for seeing.  Scarlette had chosen the performance, believing it to be a fantastical story of 'unlikely adventures on the newly-discovered star, Georgium Sidius', but the information was inaccurate and she spent much of the evening using her discretion-glass to observe the other boxes.
