"Wait at the bottom of the orchard and I'll run up to the house and fetch Claudia. She's at home to-day nursing Landry, who's in bed."

"You mascot! The very thing!"

Leaving Morland sitting under the elder bushes by the orchard gate, Lorraine made her way into the garden, and, finding one of the numerous little Castletons playing about, despatched her with a message to Claudia. The latter came out at once, Lorraine explained hurriedly, and the two girls, with some difficulty evading the curiosity of Beata, Romola and Madox, whisked down a side path into the orchard, and joined Morland. They held a very agitated council of three under the elder bushes.

"Are you certain the case isn't there?" urged Morland.

"Absolutely. I hunted for half an hour round the cave," declared Claudia.

"Then who's taken it? If it's some chance tourist who's got it, it may be returned."

Lorraine shook her head.

"I'm terribly afraid it's Madame Bertier. I believe she's mixed up in a very queer piece of business here. I want to tell you what happened yesterday."

As Lorraine recounted her adventures at St. Cyr, and the connection of the foreigner, whom she had helped to identify, with the fascinating Russian, Morland's face darkened.

"Great Heavens! Was the woman a spy after all?" he groaned. "It's the limit! What an infernal ass I've been! If she's caught with those papers on her, and they're traced to me, I'm done for—once and for all! Look here, I'm going out to the cave to have one last hunt for the case. It might have slipped behind something. Will you girls come with me?"
