My knees burned as if stung by nettles but I managed a smile.

‘I wanted to ride, Papa,’ I said. ‘And I want to go riding again.’

His eyes sparkled and his deep, happy laugh shouted out.

‘That’s my girl!’ he said in delight. ‘Want to go riding again, eh? Well, you shall. Tomorrow I shall go to Chichester and buy you a pony and you shall learn to ride at once. Riding till her knees bled at four years old, eh? That’s my girl!’

Still laughing, he led his horse around to the stable yard at the rear of the house where we could hear him shouting for a stable lad. I was left alone with Mama.

‘Miss Beatrice had better go straight to bed,’ she told Nurse, ignoring my wide-awake face. ‘She will be tired. She has done more than enough for one day. And she will not go riding again.’

Of course I went riding again. My mother was bound by all sorts of beliefs in vifely obedience and deference to the head of the household, and she never stood against my father for more than one self-forgetful second. A few days after my ride on the hunter and, alas, before the little scabs on the inside of my knees had healed, we heard a clatter of hoofs on the gravel and a ‘Holloa!’ from outside the front door.

On the gravel sweep outside the house stood my father’s hunter with Father astride. He was leaning down to lead the tiniest pony I had ever seen. One of the new Dartmoor breed, with a coat as dark and smooth as brown velvet and a sweep of black mane covering her small face. In a second my arms were round her neck and I was whispering into her ear.

Only one day later and Nurse had cobbled together a tiny version of a tailored riding habit for me to wear for my daily lesson with Papa in the paddock. Never having taught anyone to ride, he taught me as he had learned from his father. Round and round the water-meadows so my falls were cushioned by the soft earth. Tumble after tumble I took into the wet grass — and I did not always come up smiling. But Papa, my wonderful, godlike papa, was patient, and Minnie, dear little Minnie, was sweet natured and gentle. And I was a born fighter.

Only two weeks later, and I rode out daily with Papa. Minnie was on a leading rein and beside the hunter she looked like a plump minnow on the end of a very long line.

A few weeks after those first expeditions and Papa released me from the apprenticeship of the leading rein and let me ride alone. ‘I’d trust her anywhere,’ he said briefly to Mama’s murmured expostulations. ‘She can learn embroidery any time. She’d better learn to have a seat on a horse while she’s young.’

So Papa’s great hunter strode ahead and Minnie bobbed behind in a rapid trot to keep up. In the lanes and fields of Wideacre, the Squire and the little Mistress became a familiar sight as our rides lengthened from the original half an hour to the whole of the afternoon. Then it became part of the routine of the day that I should go out morning and afternoon with Papa. In the summer of 1760 — an especially dry hot summer — I was out every day with the Squire, and I was all of five.

These were the golden years of my childhood and even at that age I knew it. My brother Harry’s baby illnesses lingered on; they feared he had inherited Mama’s weak heart. But I was as fit as a flea and never missed a day out with Papa. Harry stayed indoors almost all winter with colds and rheums and fevers, while Mama and Nurse fussed over him. Then when spring was coming and the warm winds brought the evocative smells of warming land, he was convalescent. At haymaking, when I would be out with Papa to watch them scything down the tall rippling grass in great green sweeps, Harry would be indoors with his sneezing malady which started every year at haytime. His miserable ‘atchoo, ‘atchoo, would go on all through the hot days of summer, so he missed harvesting, too. At the turn of the year, when Papa promised I could go fox-cubbing, Harry would be back in the nursery or, at the best, sitting by the parlour fire with his winter ailments again.

A year older than me he was taller and plumper, but no match for me. If I succeeded in teasing him into a fight, I could easily trip him up and wrestle with him until he called for Mama or Nurse. But there was much good nature in Harry’s sweet placidity and he would never blame me for his bumps and bruises. He never earned me a beating.

But he would not romp with me, or wrestle with me, or even play a gentle game of hide-and-seek with me in the bedrooms and galleries of the Hall. He really enjoyed himself only when he was sitting with Mama in the parlour and reading with her. He liked to play little tunes on the pianoforte there, or read mournful poetry aloud to her. A few hours of Harry’s life made me unaccountably ill and tired all over. One day in the quiet company of Harry and Mama made me feel as weary as a long day in the saddle riding over the downs with Papa.

When the weather was too bad for me to be allowed out, I would beg Harry to play, but we had no games in common. As I moped round the dark library room, cheered only by finding the breeding record of Papa’s hunters, Harry would pile all the cushions he could find into the window seat and make himself a little nest like a plump wood pigeon. Book in one hand, box of comfits in the other, he was immovable. If the wind suddenly ripped a gap in the thunderclouds for the sun to pour through, he would look out at the dripping garden and say: ‘It is too wet to go out, Beatrice. You will get your stockings and shoes soaked and Mama will scold you.’

So Harry stayed indoors sucking sweets, and I ran out alone through the rose garden where every leaf, dark and shiny as holly, extended a drop of rain on its luscious point for me to lick. Every dense, clustered flower had a drop like a diamond nestling among the petals and when you sniffed the sweetness, rainwater got up your nose and made it tickle. If it rained while I was roaming, I could dive for shelter in the little white latticed summerhouse in the centre of the rose garden and watch the rain splashing on the gravel paths. But more often I would take no notice at all and walk on, on and out through the streaming paddock, past the wet ponies, along the footpath through the sheltered beech wood down to the River Fenny which lay like a silver snake in the coppice at the end of the paddock.

So although we were so near in age, we were strangers for all of our childhood. And though a house with two children in it — and one of them a romp — can never be completely still, I think we were a quiet, isolated household. Papa’s marriage to Mama had been arranged with a view to wealth rather than suitability and it was obvious to us, to the servants and even to the village, that they grated on each other. She found Papa loud and vulgar. And Papa would, too often, offend her sense of propriety by donning his Sussex drawl in her parlour, by his loud, easy laugh, and by his back-slapping chumminess with every man on our land from the poorest cottager to the plumpest tenant farmer.

Mama thought her town-bred airs and graces were an example to the county but they were despised in the village. Her disdainful, mincing walk down the aisle of the parish church every Sunday was parodied and mimicked in the taproom of the Bush by every lad who fancied himself a wit.

Our procession down the aisle, with Mama’s disdainful saunter and Harry’s wide-eyed waddle, made me blush with embarrassment for my family. Only inside our high-backed pew could I relax. While Mama and Harry stuck their heads in their hands and fervently prayed, I would sit up by Papa and slip one cold hand in his pocket.

Mama would recite prayers in a toneless murmur, but my little fingers would seek and find the private magic of my papa’s pocket. His clasp knife, his handkerchief, a head of wheat or a special pebble I had given him — more potent than the bread and wine, more real than the catechism.

And after the service, when Papa and I lingered in the churchyard to learn the village news, Mama and Harry would hurry on to the carriage, impatient of the slow, drawling jokes and fearful of infections.

She tried to belong to the village, but she had no knack of free and easy speech with our people. When she asked them how they did, or when a baby was due, she sounded as if she did not really care (which was true) or as if she found their whole lives sordid and tedious (which was also true). So they mumbled like idiots, and the women twisted their aprons in their hands as they spoke, and kept their mob caps dipped low.

‘I really fail to see what you see in them,’ Mama complained languidly after one of these abortive attempts at conversation. ‘They really are positively natural.’

They were natural. Oh, not in the sense she meant: that they were half-witted. They were natural in that they did as they felt and said what they thought. Of course they became tongue-tied and awkward in her chilly presence. What could you say to a lady who sat in a carriage high above you and asked you with every appearance of boredom what you were giving your husband for dinner that night? She might ask, but she did not care. And even more amazing to them, who believed the life of Wideacre was well known throughout the length and breadth of England, was that the Squire’s lady clearly did not know she was speaking to the wife of one of Acre’s most successful poachers, and so a true answer to the question would have been: ‘One of your pheasants, ma’am.’

Papa and I knew, of course. But there are some things that cannot be told, cannot be taught. Mama and Harry lived in a world that dealt in words. They read huge boxfuls of books delivered from London booksellers and libraries. Mama wrote long criss-crossed letters that went all over England: to her sisters and brothers in Cambridge and London, and to her aunt in Bristol. Always words, words, words. Chatter, gossip, books, plays, poetry and even songs with words that had to be memorized.
