“Marsine has been living in Germany, has he not?” he asked.

“He is a personal friend of the Kaiser,” Sogrange replied.

They both looked up and listened to the crackling of the electricity above their heads.

“I expect Bernadine is a little annoyed,” Peter remarked.

“It isn’t pleasant to be out of the party,” Sogrange agreed. “Nearly everybody, however, believed at the last moment that Sirdeller had transferred his passage to the Lusitania.”

“It’s going to cost him an awful lot in marconigrams,” Peter said. “By the bye, wouldn’t it have been better for us to have traveled separately, and incognito?”

Sogrange shrugged his shoulders slightly.

“Von Hern has at least one man on board,” he replied. “I do not think that we could possibly have escaped observation. Besides, I rather imagine that any move we are able to make in this matter must come before we reach Fire Island.”

“Have you any theory at all?” Peter asked.

“Not the ghost of a one,” Sogrange admitted. “One more fact, though, I forgot to mention. You may find it important. The Duchesse comes entirely against Von Hern’s wishes. They have been on intimate terms for years, but for some reason or other he was exceedingly anxious that she should not take this voyage. She, on the other hand, seemed to have some equally strong reason for coming. The most useful piece of advice I could give you would be to cultivate her acquaintance.”
