“During lunch, Cyrus sat next to Lady Virginia Fenwick and he was clearly overwhelmed by all her ‘member of the royal family’ and ‘distant niece of the Queen Mother’ rubbish. Afterwards, she went shopping with him in Bond Street to buy an engagement ring for his high school sweetheart, Ellie May Campbell, whom he later married. After Cyrus had bought the ring, he invited Lady Virginia back to his suite at the Ritz for tea, and the next thing he remembers is waking up in bed beside her, and the only thing she was wearing was the engagement ring.”

“That’s impressive, even by Virginia’s standards,” said Giles. “So what happened next?”

“That was when Cyrus made his first big mistake. Instead of grabbing the ring and telling her to get lost, he took the next flight back to the States. For a while, all he thought he’d lost was the ring, until Lady Virginia turned up at his wedding looking seven months pregnant.”

“Not the sort of wedding present he was hoping for.”

“Gift-wrapped. The next day, Buck Trend, one of the sharpest and meanest lawyers west of the Mississippi, gave Cyrus’s in-house lawyer a call, and once again my friend panicked. He ended up instructing his lawyer to settle before he and Ellie May returned from their honeymoon. Trend extracted more than a pound of flesh, and Cyrus ended up paying a million dollars up front, and a further ten thousand a month until the child has completed his education.”

“That’s not a bad return for a one-night stand.”

“If it ever was a one-night stand. What Virginia hadn’t bargained for was Ellie May Campbell—now Ellie May Grant—who turns out to be cut from the same Scottish cloth as her ladyship. When Cyrus finally confessed to what had taken place in London, Ellie May didn’t believe a word of Virginia’s story. She hired a Pinkerton detective and sent him across the Atlantic with instructions not to return until he’d found out the truth.”

“And did he come up with anything?” said Giles.

“He reported back that he wasn’t convinced Lady Virginia had ever had a child, and that even if she had, there was no reason to believe Cyrus was the father of the Hon. Frederick Archibald Iain Bruce Fenwick.”

“A blood test might narrow down the possibility.”

“And it might not. But in any case, while the boy’s at pre-prep in Scotland, Cyrus can hardly drop in and ask the headmaster for a sample.”

“But if he contested a paternity suit in open court the judge would have to call for a blood test.”

“Yes, but even if they turned out to share the same blood group it still wouldn’t be absolutely conclusive.”

“As I well know,” said Giles, without explanation. “So how can I help?”
