“Elegant,” I said. When we reached the bar, I ordered a Grey Goose martini, and a sauvignon blanc for Susan.

“Actually, I’ll have a Bloody Mary, very spicy, with extra lemon.”

“Should I be concerned?”

“Extreme circumstances call for extreme measures,” she said. “This crowd is right out of WASP central casting. How did they let me in?”

“We’re a forgiving people at Christmas,” I said. “Just don’t come back in January.”

“Hello, you two,” Juan Alvarez called out to us from beyond the bar. He walked toward us, resplendent in white tennis shorts, a white polo shirt with a monogram on the pocket, white Nikes, and a dangerous-looking black tennis racquet with a thick black handle. The country squire at play. If he couldn’t hit a small white ball with that weapon, we were in for a long afternoon.

Juan leaned down and kissed Susan on each cheek and then shook my hand. “Come with me. I’ll make sure you get good seats,” he said, leading us through the crowd. “Carmen does a wonderful job with these tennis matches.”

Juan waved his arm in the direction of two center-court seats. “Enjoy. When you’re ready, please go help yourself to the buffet. Now, if I may, I’ll catch up with you later,” he said, before heading in the direction of the local TV cameras set up at the other end of the barn. Their bright lights were clustered over a group of what I assumed were the celebrities Carmen had talked into participating in the event.

We could see Carmen coming through the crowd, trailed by a man with a microphone and two cameramen. She was wearing white shorts that showed a pair of long, well-muscled legs, and a navy blue V-neck top. Her long, dark hair was pulled back in a ponytail and tied with red, white, and blue ribbon. She looked up into the stands, saw us, and after a quick word with the reporter, ran up the stairs, taking them two at a time. “Hello there! I’m so glad to see you.” She gave Susan a kiss on the cheek and me an enthusiastic hug.

“I have to go warm up, but I wanted to say hi first. I really appreciate you coming out here for this.” She nodded in my direction. “I’ll bet you would rather do most anything else, wouldn’t you?”

“I’m considering this a research trip,” I said.

“Don’t mind him,” Susan said. “I’m looking forward to seeing what happens next.”

“Hey, Carmen!” a young woman called from behind us. Carmen turned. “Kim!” They embraced. “You made it! How’s the baby?”

“Fantastic! Hey, you look great. Retirement definitely agrees with you,” Kim said.

“Kim, let me introduce you to my friends. Susan and Spenser, Kim Clijsters.”

“Great to meet you,” Kim said. “Carmen, I’m going to clean your clock today. Love you!”

“So that’s what happens next,” I said.

“No,” Carmen said. “First mixed doubles. Two civilians, two pros. One set. Then one set of men’s singles, then one set between Kim and me. Then we all go home.”

“And how long do you think this orgy of tennis talent will take?”

“What do you think, Kim? Four, maybe five hours?” Carmen turned to Kim, who was laughing.

“I don’t know how well you know Carmen, but she’s a bad one. One hour, tops, unless we get into tiebreakers.”

“All right, time to get ready. Head over and get some crab cakes before they’re all gone,” Carmen said. The two friends walked off, arm in arm.

“She’s adorable,” Susan said. “All that talent, and a dimple, too.”

We made our way to the buffet table, where Susan put a small spoonful of vegetables and another of salad on her plate.

“Thanks for not showing me up,” I said, helping myself to prime rib, mashed potatoes, and glazed baby carrots.

We took seats at a table as the mixed doubles got under way. Juan was partnered with a woman I thought was Martina Navratilova. Playing opposite them were John McEnroe and Rita Fiore. I noted Rita’s white tennis costume, a fitted low-cut top and short pleated skirt, which showed off her spectacular legs. A little man sat atop the umpire’s chair while a man in a tan uniform flipped big plastic numbers.

Slide had been pressed into service as one of the ball boys. He ran back and forth across the rear of the court, his face a mask of concentration. A young girl in pigtails worked the other side of the court.

“I had no idea Rita played tennis,” Susan said.

“She’s a woman of many talents,” I said as I watched her smash a serve into the opposite court. Juan could only watch it go by.

“Forty love,” the umpire called. Rita and John were winning. It didn’t seem to be much of a contest.

WE FINISHED OUR MEAL and returned to our seats in the stands as the doubles were wrapping up. Rita and John had beaten Juan and Martina, though it had gone to a tiebreaker.

“I think now would be a good time to console Juan on his loss,” I said to Susan. “Keep my seat warm.”

Susan nodded. The crowd was loud and enthusiastic. I made my way through the throng to Juan. “Sorry about the match, but you put up a good fight,” I said.

Juan smiled. “Playing with Martina is honor enough.”

“You must be proud of Carmen for putting this all together. It’s quite a party.”

“She’s really something, don’t you think?” Juan said.

There was a tone of longing, perhaps, in his voice. As if he knew that he had lost her and he knew why and now his prize possession was soon to leave him. It didn’t matter that he was the one to send her away permanently. Maybe he even loved her. Pity me that the heart is slow to learn what the swift mind beholds at every turn.

On my way back to my seat I went over to one of the dark-skinned men who were watching the match. “You Martita’s brother?” I said.

He shook his head and pointed down the way to the next man standing guard. I walked over to him and stuck my hand out. “I’m Spenser. I took Martita and her baby to the health clinic last week, remember?”

The tall, heavyset man grinned at me, showing a lot of gold. “Muchas gracias, señor.”

“Sorry, I only speak a little Spanish.”

“I’m Marco. What can I do for you?” He kept his gaze on the tennis match while he was talking.

“I just wanted to say hello. Carmen tells me you’re the security guard here. That’s a pretty big responsibility, protecting all these people.”

Marco grinned. “I am but one of many. Mr. Alvarez has . . .” He stopped to count. “He has ten guards here.”

“But that’s because it’s a big event today, right?”

Marco shook his head. “No, we are ten to twelve most of the time. Three shifts of four men. Sometimes more, sometimes less when Mr. Alvarez travels. But mostly ten to twelve.”

“Good to know,” I said. “I’m sure you are well trained.”

“Sí,” he said, and his grin broadened. “And we are well armed.”

“Did Carmen tell you I’m a private detective? I use a Beretta. Easy to handle, gets the job done.”

“Smith and Wesson’s a good weapon for close range. We have a snub-nose .38 special every time. Or for the ankle, a .25 Beretta.” Marco was enthusiastic.

“Rifles?”

“For hunting. Not much for our work.”

A burst of static sounded from Marco’s right ear. I hadn’t noticed his earpiece. Marco listened, then leaned into a microphone at his shoulder and said, “Sí. On my way.

“I have to go now,” he said. “Nice speaking with you, Spenser. Thank you for helping Martita.”

I went back to where Susan was sitting just in time to see Carmen and Kim take the court.

The umpire stepped forward for the coin toss to determine the first serve. Kim won the toss, and she and Carmen took their places.

Kim bounced in place at the baseline. She looked across the net at Carmen to make sure she was ready to start.

Her first serve whizzed over the net and hit the line.

Carmen watched it go by. She smiled at Kim and walked to the other side of the court. Kim served again. Another ace. No smile from Carmen this time. Athletes are all the same. Friendship gives way to the competitive spirit every time.
