Granddad shook his head. “No. It was a civil suit. Made all the headlines.”

“What was it about?”

“If I remember right it was a motorcar engine,” Granddad said. “Some bloke took Sir Toby to court, claiming that they had designed a motorcar engine together and then Sir Toby had claimed the whole thing as his own and cut the other bloke out. Sir Toby hired a top-notch barrister who proved that the other bloke had been driven off his rocker by being in the trenches and had delusions. Might have been true, of course. The war did strange things to a lot of blokes. Anyway, this bloke lost the case and hanged himself.”

“Do you remember what his name was?” I asked.

Granddad sucked through his teeth as he did when he was thinking. “Some German type of name. That’s why there was little sympathy for him, even though he’d been in the trenches like all the other poor blokes. Sherman? That’s what it was. Johann Sherman. He was a Jew, I believe, who’d left Germany as a young man.”

“Then that’s it. The man who was threatening Sir Toby. I think his name was Schumann,” I said. “That’s close enough, isn’t it?”

“Which man was this?” Germain asked sharply.

I told them about what I had overheard and how Johnson had said it was some kind of business deal gone wrong.

“Again he should be easy enough to locate—businessman or crook, perhaps. I will have a private word with the commissioner down here and maybe put some of my men from the Sûreté on to tracking this Schumann.”

“Hang on a minute,” Granddad said, making us all pause in our tracks. “When that necklace was stolen—you said the flashbulbs went off, right?”

I nodded.

“Before or after you fell?”

“Both, I think.”

“If someone took a picture of you being helped up, then it’s possible that one of the cameras caught the robbery.”

“Excellent,” Germain said. “Why don’t you and Lady Georgiana make a tour of the newspapers and press services here, while I confer with my colleagues and decide how best to intervene here without it looking like intervention.”

“I’m anxious to find the girl who impersonated me,” I said. “Don’t you think that should come first?”

“I will take your charming grandfather,” Coco said. “It will help to have a person like me who is used to dealing with these photographers. I know many of them and I am known to them all.”

“Bob’s yer uncle,” Granddad said.

“What has my uncle got to do with this?” Coco asked, looking bewildered.
