I raised my eyebrows at him, and he grinned. “I didn’t manage to take as much of the favorite as I wanted on the exchanges. Damn Internet link went down.”

“Just us or everyone?” I asked seriously.

“Dunno,” he said, intrigued. “I’ll find out.”

Luca and I started to pack up our equipment as Betsy paid out the occasional winning ticket. Most of the racegoers were streaming for the exits to try to beat the traffic jams, and, no doubt, there would be more winning tickets from the last race handed in the following day.

We kept a record on our computer of all the bets taken, both winning and losing, and it never ceased to amaze me how many of the winning tickets were never cashed. Presumably some were lost, and perhaps some inebriated punters didn’t realize they were winners, but almost every day there were two or three winning bets that were never claimed. “Sleepers,” they were called, and they were like a cash bonus for us. But it was one we could never completely rely on. Our tickets didn’t have an expiry date on them, and, only the day before, I’d had to cash a sleeper from the Royal Ascot Meeting of the previous year. Maybe it had been hiding for twelve months in the deep recesses of someone’s morning-coat pocket, or tucked into the hatband of a topper, waiting quietly to be discovered and paid out.

The crowd had mostly dispersed to the parking lots by the time Luca, Betsy and I had packed up the majority of our gear and loaded it onto our little wheeled trolley that ingeniously doubled up as a base for our computer during the racing. The betting ring was deserted save for the other bookmakers, who, like us, were packing up amongst the detritus of a day’s gambling: discarded newspapers, torn-up betting slips, crumpled coffee cups and half-eaten sandwiches.

“Do you fancy a beer?” Luca asked as I pulled one of the elastic straps over our equipment.

“I’d love one,” I said, looking up at him. “But I can’t. I have to go and see Sophie.”
