Danny occasionally glanced at the man with the cigar, but there was no sign that he was bidding for any of the early lots. He hoped his interest was in the de Coubertin envelope, otherwise why would Blundell have pointed him out?

By the time the auctioneer had reached Lot 35, an assortment of Commonwealth stamps, which was disposed of in less than thirty seconds for £1,000, Danny was becoming increasingly nervous. Lot No. 36 caused an outbreak of chatter, which made Danny check his catalog once again: the 1861 Cape of Good Hope four-penny red, one of only six known in the world.

Blundell opened the bidding at £30,000, and after some dealers and a few minor collectors had dropped out, the only two bidders left appeared to be the man with the cigar and an anonymous telephone bidder. Danny watched the man with the cigar very closely. He didn't seem to give any sign that he was bidding, but when Mr. Blundell finally received a shake of the head from the woman on the phone, he turned back to him and said, "Sold to Mr. Hunsacker for seventy-five thousand pounds." The man smiled and removed the cigar from his mouth.

Danny had become so engrossed in the bidding war that had just taken place that he was taken by surprise when Mr. Blundell announced, "Lot number thirty-seven, a unique envelope showing an eighteen ninety-six first edition of a stamp issued by the French government to celebrate the opening ceremony of the modern Olympic Games. The envelope is addressed to the founder of the Games, Baron Pierre de Coubertin. Do I have an opening bid of a thousand pounds?" Danny was disappointed that Blundell had started the bidding at such a low figure, until he saw several paddles being raised around the room.

"Fifteen hundred?" Almost as many.

"Two thousand?" Not quite as many.

"Two thousand five hundred?" Mr. Hunsacker kept the unlit cigar in his mouth.

"Three thousand?" Danny craned his neck and peered around the room, but couldn't see where the bidding was coming from.

"Three thousand five hundred?" The cigar remained in the mouth.

"Four thousand. Four thousand five hundred. Five thousand. Five thousand five hundred. Six thousand." Hunsacker removed his cigar and frowned.

"Sold, to the gentleman in the front row, for six thousand pounds," said the auctioneer as he brought the hammer down. " Lot thirty-eight, a rare example of..."

Danny tried to see who was seated in the front row, but he couldn't work out which one of them had bought his envelope. He wanted to thank them for bidding three times the high estimate. He felt a tap on his shoulder, and looked around to see the man with the cigar towering over him.

"My name is Gene Hunsacker," he said in a voice almost as loud as the auctioneer's. "If you'd care to join me for a coffee, Sir Nicholas, it's possible that we may have something of mutual interest to discuss. I'm a Texan," he said, shaking Danny by the hand, "which may not come as a big surprise, as we met in Washington. I had the honor of knowing your grand-daddy," he added as they left the room and walked down the stairs together. Danny didn't say a word. Never offer hostages, he had learned since he had begun playing the role of Nick. When they reached the ground floor, Hunsacker led him into the restaurant and headed for another seat that appeared to be his by right.

"Two black coffees," he said to a passing waiter, without giving Danny any choice. "Now, Sir Nicholas. I'm puzzled."

"Puzzled?" said Danny, speaking for the first time.

"I can't work out why you let the de Coubertin come up for auction, and then allowed your uncle to outbid me for it. Unless you and he were working together, and hoped you could force me to go even higher."

"My uncle and I are not on speaking terms," said Danny, selecting his words carefully.

"That's something you have in common with your late grand-daddy," said Hunsacker.

"You were a friend of my grandfather's?" asked Danny.

"Friend would be presumptuous," said the Texan. "Pupil and follower would be nearer the mark. He once outfoxed me for a rare two-penny blue way back in 1977 when I was still a rookie collector, but I learned quickly from him and, to be fair, he was a generous teacher. I keep reading in the press that I have the finest stamp collection on earth, but it just ain't true. That honor goes to your late grand-daddy." Hunsacker sipped his coffee before adding, "Many years ago he tipped me off that he'd be leaving the collection to his grandson, and not to either of his sons."

"My father is dead," Danny said.

Hunsacker looked surprised. "I know-I was at his funeral. I thought you saw me."

"I did," said Danny, recalling Nick's description of the vast American in his diary. "But they would only allow me to speak to my solicitor," he added quickly.

"Yes, I know," said Hunsacker. "But I managed to have a word with your uncle and let him know that I was in the market should you ever want to dispose of the collection. He promised to keep in touch. That's when I realized that he hadn't inherited it, and that your grand-daddy must have kept his word and left the collection to you. So when Mr. Blundell phoned to tell me that you'd put the de Coubertin up for sale, I flew back across the pond in the hope that we might meet."

"I don't even know where the collection is," admitted Danny.

"Maybe that explains why Hugo was willing to pay so much for your envelope," said the Texan, "because he has absolutely no interest in stamps. There he is now." Hunsacker pointed his cigar at a man standing at the reception desk. So that's Uncle Hugo, Danny thought, taking a closer look at him. He could only wonder why he wanted the envelope so badly that he'd been willing to pay three times its estimated value. Danny watched as Hugo passed a check to Mr. Blundell, who in return handed over the envelope.

"You're an idiot," muttered Danny, rising from his place.

"What did you say?" asked Hunsacker, the cigar falling out of his mouth.

"Me, not you," said Danny quickly. "It's been staring me in the face for the past two months. It's the address he's after, not the envelope, because that's where Sir Alexander's collection has to be."

Gene looked even more puzzled. Why would Nick describe his grandfather as Sir Alexander?

"I have to go, Mr. Hunsacker, I apologize. I should never have sold the envelope in the first place."

"I wish I knew what in hell's name you were talking about," said Hunsacker, taking a wallet from an inside pocket. He passed a card across to Danny. "If you ever decide to sell the collection, at least give me first option. I'd offer you a fair price with no ten percent deduction."

"And no twenty percent premium either," said Danny with a grin.

"A chip off the older block," said Gene. "Your grand-daddy was a brilliant and resourceful gentleman, unlike your uncle Hugo, as I'm sure you realize."

"Goodbye, Mr. Hunsacker," said Danny as he tucked the card into Nick's wallet. His eyes never left Hugo Moncrieff, who had just put the envelope into a briefcase. He walked across the lobby to join a woman Danny hadn't noticed until that moment. She linked her arm in his and the two of them left the building quickly.

Danny waited for a few seconds before following them. Once he was back on Bond Street, he looked left and then right, and when he spotted them he was surprised by how much ground they'd already covered. It was clear they were in a hurry. They turned right as they passed the statue of Churchill and Roosevelt sitting on a bench, and then left when they reached Albemarle Street, where they crossed the road and walked for a few more yards before disappearing into Brown's Hotel.
