The mingled smells of hot horse and cold river mist filled my nostrils. I could hear only the swish and thud of galloping hooves and the occasional sharp click of horseshoes striking against each other. Behind me, strung out, rode a group of men dressed like myself in white silk breeches and harlequin jerseys, and in front, his body vividly red and green against the pale curtain of fog, one solitary rider steadied his horse to jump the birch fence stretching blackly across his path.

All, in fact, was going as expected. Bill Davidson was about to win his ninety-seventh steeplechase. Admiral, his chestnut horse, was amply proving he was still the best hunter 'chaser in the kingdom, and I, as often before, had been admiring their combined back view for several minutes.

Ahead of me the powerful chestnut hindquarters bunched, tensed, sprang: Admiral cleared the fence with the effortlessness of the really good performer. And he'd gained another two lengths, I saw, as I followed him over. We were down at the far end of Maidenhead racecourse with more than half a mile to go to the winning post. I hadn't a hope of catching him.

The February fog was getting denser. It was now impossible to see much farther than from one fence to the next, and the silent surrounding whiteness seemed to shut us, an isolated string of riders, into a private lonely limbo. Speed was the only reality. Winning post, crowds, stands, and stewards, left behind in the mist, lay again invisibly ahead, but on the long deserted mile and a half circuit it was quite difficult to believe they were really there.

It was an eerie, severed world in which anything might happen. And something did.

We rounded the first part of the bend at the bottom of the racecourse and straightened to jump the next fence. Bill was a good ten lengths in front of me and the other horses, and hadn't exerted himself. He seldom needed to.
