But he did not accept defeat. Instead, he’d turned his many talents to convincing those around him that a well-planned joint invasion by the French king and the Scots could set things right again, restore the exiled Stewarts to their rightful throne.

They nearly had succeeded.

History remembered the tragic romance of Culloden and Bonnie Prince Charlie, years after Hooke’s time. But it was not in that cold winter at Culloden that the Jacobites—quite literally, the ‘followers of James’, and of the Stewarts—came closest to a realization of their purpose. No, that happened in the spring of 1708, when an invasion fleet of French and Scottish soldiers, Hooke’s idea, anchored off the coast of Scotland in the Firth of Forth. On board the flagship was the tall, twenty-year-old James Stewart—not the James who had fled England, but his son, whom many, not only in Scotland but in England, accepted as their true king. On shore, assembled armies of the highlanders and loyal Scottish nobles waited eagerly to welcome him and turn their might against the weakened armies to the south.

Long months of careful preparations and clandestine plans had come to their fruition, and the golden moment seemed at hand, when once again a Stewart king would claim the throne of England.

How this great adventure failed, and why, was one of the most fascinating stories of the period, a story of intrigue and treachery that all sides had tried hard to cover up and bury, seizing documents, destroying correspondence, spreading rumors and misinformation that had been believed as fact down to the present day.

Most of the details that survived had been recorded by Nathaniel Hooke.

I liked the man. I’d read his letters, and I’d walked the halls of Saint-Germain-en-Laye, where he had walked. I knew the details of his marriage and his children and his relatively long life and his death. So it was frustrating to me that, after five long months of writing, I still struggled with the pages of my novel, and Hooke’s character refused to come alive.

I knew Jane sensed that I was having trouble—as she said, she’d known me far too long and far too well to overlook my moods. But she knew, too, I didn’t like to talk about my problems, so she took care not to come at me directly. ‘Do you know, last weekend I read through those chapters that you sent me—’

‘When on earth do you have time to read?’

‘There’s always time to read. I read those chapters, and I wondered if you’d ever thought of telling things from someone else’s point of view…a narrator, you know, the way Fitzgerald does with Nick in The Great Gatsby. It occurred to me that someone on the outside could perhaps move round more freely, and link all the scenes together for you. Just a thought.’ She left it there, and no doubt knowing that my first response to anyone’s advice was staunch resistance, changed the subject.

Nearly twenty minutes later, I was laughing at her dry descriptions of the joys of diapering a newborn, when her husband, Alan, thrust his head around the doorway of the bedroom.

‘You do know there’s a party going on downstairs?’ he asked us, with a scowl I would have taken much more seriously if I hadn’t known it was all bluff. He was a softie, on the inside. ‘I can’t entertain this lot all on my own.’

‘Darling,’ Jane replied, ‘they are your relatives.’

‘All the more reason not to leave me alone with them.’ But he winked at me. ‘She’s not got you talking shop, I hope? I told her she’s to let you be. She’s too concerned with contracts.’

Jane reminded him, ‘Well, that’s my job. And for your information, I am never in the least concerned that Carrie’s going to break a contract. She has another seven months before the first draft’s due.’

She’d meant for that to cheer me, but I think that Alan must have seen my shoulders sag, because he held his hand to me and said, ‘Come on, then. Come downstairs and have a drink, and tell me how the trip was. I’m amazed you made it all that way in time.’

There were enough jokes floating round about my tendency to get distracted when I traveled, so I opted not to tell them anything about my detour up the coast. But it reminded me, ‘Alan,’ I asked, ‘are you flying tomorrow?’

‘I am. Why?’

Alan’s little fleet of helicopters helped to serve the off-shore oil rigs dotted through the North Sea off the rugged coast of Peterhead. He was a fearless pilot, as I’d learned the one and only time I’d let him take me up. I’d barely had the legs to stand when he’d returned me to the ground. But now I said, ‘I wondered if you’d fly me up the coast a bit. Nathaniel Hooke came over twice from France, to intrigue with the Scottish nobles, and both times he landed at the Earl of Erroll’s castle, Slains, which, from the map I’ve got, the old one, looks to be somewhere just north of here. I’d like to see the castle, or what’s left of it, from out at sea, the way it would have looked to Hooke when he first saw it, coming over.’

‘Slains? Aye, I can take you over that. But it’s not up the coast, it’s down. At Cruden Bay.’

I stared. ‘Where?’

‘Cruden Bay. You would have missed it, coming up the way you did.’

Jane, sharp as ever, noticed something in my face, in my expression. ‘What?’ she asked.

I never ceased to be surprised by serendipity—the way chance happenings collided with my life. Of all the places that I could have stopped, I thought. Aloud I only said, ‘It’s nothing. Could we go tomorrow, Alan?’
