Jack, who had expected the relapse, called in a doctor, but Lydia refused to see him. The next day she received the lawyer.

She had only briefly outlined the part which Marcus Stepney had played in her rescue, but she had said enough to make Jack call at Stepney's hotel to thank him in person. Mr. Stepney, however, was not at home—he had not been home all night, but this information his discreet informant did not volunteer. Nor was the disappearance of the Jungle Queen noticed for two days. It was Mrs. Cole-Mortimer, in settling up her accounts with Jack, who mentioned the "yacht."

"The Jungle Queen," said Jack, "that's the motor-launch, isn't it? I've seen her lying in the harbour. I thought she was Stepney's property."

His suspicions aroused, he called again at Stepney's hotel, and this time his inquiry was backed by the presence of a detective. Then it was made known that Mr. Stepney had not been seen since the night of Briggerland's arrest.

"That is where they've gone. Stepney was very keen on the girl, I think," said Jack.

The detective was annoyed.

"If I'd known before we could have intercepted them. We have several destroyers in the harbour at Villafrance. Now I am afraid it is too late."

"Where would they make for?" asked Jack.

The officer shrugged his shoulders.

"God knows," he said. "They could get into Italy or into Spain, possibly Barcelona. I will telegraph the Chief of the Police there."
