Ruth was secretly much disturbed by Clare’s story. She believed that she knew something about the pair of crooks who were accused—Rose Mantel’s two friends—that might lead to their capture. She was sure Henriette Dupay and she had passed them with their stalled automobile on the road to Lyse that morning.

In addition, she believed the two crooks were connected with those people at the Chateau Marchand, who were supposed to be pro-German. Now she knew what language she had heard spoken by José and the hard-featured Bessie of the chateau, there by the wayside cross. It was Spanish. The woman might easily be a Mexican as well as José.

Should she go to the prefect of police and tell him of these things? It seemed to Ruth Fielding that she was much entangled in a conspiracy of wide significance. The crooks who had robbed the Red Cross seemed lined up with the spies of the Chateau Marchand.

And there was the strange animal—dog, or what-not!—that was connected with the chateau. The werwolf! Whether she believed in such traditional tales or not, the American girl was impressed with the fact that there was much that was suspicious in the whole affair.

Yet she naturally shrank from getting her own fingers caught in the cogs of this mystery that the French police were doubtless quite able to handle in their own way, and all in good time. It was evident that even Mrs. Mantel was not to be allowed to escape the police net. She had not been arrested yet; but she doubtless was watched so closely now that she could neither get away, nor aid in doing further harm.

As for Clare Biggars, she was perfectly innocent of all wrong-doing or intent. And she was quite old enough to take care of herself. Besides, her father would doubtless be warned that his daughter was under suspicion of the French police and he would communicate with the United States Ambassador at Paris. She would be quite safe and suffer no real trouble.

So Ruth decided to return to Clair without going to the police, and, after lunch, having delivered the bags of grain which had filled the tonneau of the car, she and Henriette Dupay drove out of town again.

They were delayed for some time by tire trouble, and the French girl proved herself as good a mechanic as was necessary in repairing the tube. But night was falling before they were halfway home.

Ruth’s thoughts were divided between the conspiracy, in which Mrs. Mantel was engaged, and her worry regarding Tom Cameron. She had filed a telegraph message at the Lyse Hospital to be sent to Tom’s cantonment, where he was training, and hoped that the censor would allow it to go through. For she knew she could not be satisfied that Tom had not been wounded until she heard from him.

The American girl’s nerves had been shot through by the affair of the early morning, when the note from Tom had been brought to her. What had followed since that hour had not served to help her regain her self-control.
