She had seen me come into the room but had carried on singing even louder than before. She simply couldn’t stop. And so it had gone on all night and into the following day. I couldn’t reason with her. Eventually, in desperation and fear, I had called the doctor.

This manic state had lasted for nearly a week, with her spending much of the time in bed asleep and heavily sedated. When awake, she had hardly stopped talking or singing, and she was greatly irritated when interrupted.

And then, almost as quickly, she had dived into a deep depression, refusing to eat and blaming herself for all the ills of the world. It was irrational and obsessive behavior, but she believed it absolutely. Sedatives were exchanged for antidepressants, and for a while we didn’t seem to know whether she was going up or down.

Mental illness can be very frightening, and I was utterly terrified. Physical disease usually manifests itself with visible symptoms-a rash, a fever or a swelling. And there is nearly always some pain or discomfort to which the patient can point and describe.

However, a sickness of the mind, and its function, has no such easy-to-understand physical indicators. Sufferers appear just as they did before the disorder hit, and often, as in Sophie’s case, have no comprehension that they are ill. To them, their behavior appears quite normal and logical. It is everyone else who’s mad for even suggesting they need psychiatric help in the first place.

The plans for a family that I had initially placed on hold had, by now, been well and truly switched off. The little bedroom, which had long ago become my office and storeroom, would, it seemed, never contain a cot and teddy bears, at least not while Sophie and I owned the house.

It was not just that Sophie was too often ill to look after a child, it was also the risk that a pregnancy would cause an upset to her hormones that could tip her over entirely into a void from which she would never recover. Postnatal depression can severely debilitate even the sanest of mothers, so what might it do to Sophie? And even though a professor of psychiatry had told us it wasn’t likely, there was some evidence to suggest that manic depression could be a hereditary condition. I was wary of creating a manic-depressive child. For ten years I had witnessed the destruction from within of a bubbly, lively and fun-loving young woman. I didn’t relish the thought of the same thing happening to my children.

I supposed I still loved Sophie, although after five months of medically enforced separation I was sometimes unsure. It was true that, during those months, there had occasionally been some good moments, but they had been rare, and mostly we existed in limbo, our lives on pause, waiting for someone to push the PLAY button if things improved.

We had definitely been dealt a bum hand in life. Sophie’s parents, typically and loudly, had blamed me for their daughter’s illness, while I silently blamed them back for rejecting her over her choice of husband. The doctors wouldn’t say for sure if that had been a factor in her illness, but it certainly hadn’t helped.

Alice, Sophie’s younger sister, constantly said I was a saint to stick by her all these years. But what else could I do? It wasn’t her fault she was ill. What sort of husband would desert his wife in her time of need? “In sickness and in health,” we had vowed, “until death us do part.” Perhaps, I thought, death would indeed be the only way out of this nightmare.

I shook myself out of these morbid thoughts, let myself into the house and went straight to bed.

Thursday at Royal Ascot is Gold Cup Day. It is also known as “Ladies Day,” when the female of the species preens herself in her best couture under an extravagant hat she wouldn’t be seen dead in at any other time or place.

This particular Thursday the sun had decided to play the game, and it was shining brightly out of a clear blue sky. The champagne flowed and seafood lunches were being consumed by the trawlerload. All was set for a spectacular day of racing. Even I, a cynical bookie, was looking forward to it all with hope and expectation for another bunch of long-priced winners.

“Didn’t walk into another door, then?” asked Larry Porter as he set up his pitch next to ours.

“No,” I replied. “No doors in the parking lot last night.”

He grinned at me. “And all that cash yesterday.” He rubbed his hands. “Fancy trying to rob you on Tuesday when you’re broke, then let you off yesterday with bulging pockets. Bloody mad.”

“Yes,” I said quietly, wondering once again if it really had been an attempted robbery in the first place.

“Let’s hope we have bulging pockets again today,” Larry said, still smiling.

“Yes,” I said again, my mind still elsewhere.

Larry Porter and I could not be properly described as friends. In truth, I didn’t have any friends amongst my fellow bookmakers. We were competitors. Many punters believed that there was an ongoing war between them and the bookies, but, in fact, the really nasty war was between the bookmakers themselves. Not only did we fight for the custom of the general public, we fought hardest and dirtiest amongst ourselves, betting and laying horses, doing our utmost to get one over on our neighbors. There was very little love lost between us and, whereas Larry had been genuinely concerned that I had been mugged in the parking lot, it was more because he saw a danger to himself than out of compassion for any injury or loss that I had sustained.

Many in the racing industry, both privately and publicly, called all bookmakers “the enemy.” They accused us of taking money out of racing. But we were only making a living, just like them. They too bought their fancy cars and enjoyed their foreign holidays, and what was that if it wasn’t “taking money out of racing”? The big firms, although no friends of mine, spent millions of their profits on race sponsorship, and we all paid extra tax on gambling profits on top of the “levy,” a sum that was also taken from bookmakers’ profits and put back into racing via the Horserace Betting Levy Board.

The betting levy provided more than half the country’s total race prize money, as well as contributing to the cost of the dope testing, the patrol cameras and the photo-finish systems. Plenty of the trainers hated all bookmakers with a passion, but they still bet with them, and they couldn’t seem to see that the future of racing, and consequently their own futures, relied totally on the public continuing to gamble on the horses.

“Larry,” I said, “did your Internet go down just before the last race on Tuesday?”

“I believe it did,” he said. “But it happens all the time. You know that.”

“Yes,” I said. “But did you know that all the mobile phones went off at the same time?”

“Did they indeed,” he said. “Anyone hit?”

“Not that I know of,” I replied.

“I’ll bet there was quite a queue at the pay phone on the High Street,” he said with a laugh. There was a public telephone just outside the racetrack, one of the few remaining now that everyone seemed to have a mobile.

“Yeah,” I said, joining in with his amusement, “I bet you’re right.”

Business was brisk in the run-up to the first race. As always when there was a really big crowd, many punters liked to place all their bets for the whole day before the first so that they didn’t have to relinquish their viewing spots between races. Acquiring seats in the Royal Enclosure viewing area on the fourth floor of the grandstand was as difficult as obtaining a straight answer from a politician. Once secured, they were not given up lightly.

Consequently, we were taking bets for all races, able to quote our odds thanks to the prices offered on the Internet gambling sites, where bets would have been made all morning. Again, it was the computer running the show, with us humans at its beck and call.
