22 Hans Square was actually a boarding school, but a bed wasn't required for a five year old living three doors away.
At first, Letitia merely delighted in her surroundings, found much to thrill her mind, then went home to Mum and Dad when classes were over for the day. It seems to have not been - nor caused - any hardship that she was not only so young, but ten years the junior of every other girl there.
Perhaps Mrs Rowden tailored her lessons accordingly. Maybe Letitia simply could keep up. The clue might be in what happened next.
In 1809, when she was seven years old, her father reached a decision about his lot. He had been in the military, but now determined that he was going to make a go of farming. Not in his native Herefordshire - that would be too humiliating - but back in Trevor Park, Hertfordshire. The Landon house in Hans Square was packed up and the whole family came with him.
Letitia was not impressed. She was far away from where she wanted to be, and she was bored.
Her father called upon his niece, Elizabeth Landon, to move in with them. She was his brother Samuel's daughter and a well educated young lady of nineteen years old. Perfect for acting as a governess for little Letitia. Or so he thought.
The reality quickly asserted itself. Letitia was simply too intelligent. At seven, she'd already far out-stripped her adult cousin. Elizabeth was magnanimous about it. In fact, she appeared downright proud of her young charge, later recalling,
'In very many instances, in endeavoring to teach, I have myself been taught, the extraordinary memory and genius of the learner soon leaving the humble abilities of the teacher far behind.'
The seven year old had already memorized massive sections of Sir Walter Scott's The Lady of the Lake, especially the battle scenes, which she recited with malice aforethought into her brother's face. She was reading Keats, Byron and Petrarch; devouring Robinson Crusoe and the Arabian Nights; and traveling to Africa, via her imagination, as prompted by travel books.
Her family gave up and sent her back to 22 Hans Square as a boarder.
For the rest of her life, she would consider her school to be home. Letitia refused point blank to graduate. As she grew into an adult, her travels might take her halfway across the world, but when she returned to Britain, it was to the school, not her family home.
