Charlotte lost her head. As Miss Knight left her to go to the Prince, she rushed up to her bedroom, seized a bonnet, ran down the back stairs, out of the house and – swollen knee forgotten – full-tilt into the street. Here she ran hither and thither, uncertain which way to go, until, by one account, a kindly young man, the nephew of a Pall Mall picture dealer, saw her from a window and came to her aid. Breathlessly, she begged him to call her a hackney cab, which – having no idea – who she was – he did, and she offered the driver a guinea to drive her – ‘towards Oxford Street’. She may have been careful not to betray her destination: on the other hand, never having been out by herself before, she may have been a little uncertain of the way to her mother’s house in Bayswater, which was where she planned to go. The jarvey, whose name was Higgins, obediently took her to the top of Regent Street, and by this time she had recovered her confidence enough to tell him to drive on to Connaught Place, the Princess of Wales’s house – and to drive faster.
It is not known just when the cabby tumbled to the identity of his fare, but no doubt he was he was suitably surprised and obsequious when the young Princess, arrived on her mother’s doorstep, handed him three guineas.
The excitement of her flight was slightly damped when she learned that her mother was not at home,having gone to Blackheath ‘on business’. A groom was sent off post-haste to bring her back, and Charlotte was left to cool her heels. All that she could think of to do was to order dinner; and she then decided to send for her uncle Sussex, and despatched a messenger with a scribbled note. She also summoned Mr. Brougham. As it happened, both were dining out and had to be run to earth, which caused a further delay.
At about nine o’clock the Princess of Wales arrived, accompanied by Lady Charlotte Lindsay. She had been met on the road by the galloping groom, and had hurried back, only stopping at the House of Commons to try and find Mr. Whitbread, who was not there.
She now heard the whole story. Charlotte threw herself upon her mother’s protection and announced that she wished to live with her always. To this the Princess of Wales was non-committal, and it is noticeable in Brougham’s account of what followed that she is oddly silent: Charlotte’s proposal did not entirely accord with her plans.
Brougham, who had been up all the night before on a legal case, was desperately tired when the summons reached him, and fell asleep in the carriage that was sent to fetch him to Connaught Place. Thinking that he was sent for by the Princess of Wales, he dreaded the effort that lay before him as he ‘stumbled upstairs, still half asleep, to the drawing-room’. Here, to his astonishment, he found Princess Charlotte, who rushed forward and seized both his hands, saying how impatient she had been at the delay. ‘I have run off,’ she announced. She was radiant, and brushed aside his questions, declaring, ‘Oh it is too long to tell now.’
