Told in a straightforward slightly self-deprecating style, Mary's is truly an extraordinary story, and, has been remarked more than once, an illustration of the oft-cited adage that it's not how good you are - it's how much you want it. As a child she was self-confessedly 'hopeless - it took me a whole year to learn rising trot', but her single-minded pursuit of success from Pony Club to her dream of winning Badminton (and of course much, much more) is impressive. Before a combination of sponsors, prize-monies and her producing and breeding programme gave her some solvency, she took on any jobs she could to make ends meet, which included cleaning out toilets, a butcher's delivery round, and driving HGVs at night: while hard work, impossibly high standards, and a dearth of cheap praise were instilled early on as a teenager at Sheila Willcox's yard. In case we thought she was only about horses, Mary relates how she ticked off her other plans and ambitions: sailing (a tall ship trip on a sailing bursary), a cordon bleu cookery course, a season as a chalet girl, and as much world travel and adventure as she could fit in. Future biographers will delve and expose more of the personal life which is sketched here; this is not a tale for the pruriently curious. Nor is it a tale for the squeamish. The cross-country course of challenges, disasters, mad dashes, bitter disappointments, and ecstatic successes, is punctuated with some real tragedies, and two of these have stuck in my mind: Caroline Pratt's death in a water complex at Burghley in 2004, and 'Call Again Cavalier' breaking his leg and having to be put down at Cardiff in 2008. But Mary is still forging ahead - she will be 50 this year, and one cannot but raise one's hat in acknowledgment to a remarkable horsewoman. A thoroughly good read.
