All the guests laughed and talked at the same time. Suddenly the countess began to sing again in a low voice: “Knowest thou the land?” from “Mignon.”

The others listened with delight.

Down the avenue a vehicle was heard approaching. There was a cloud of dust enveloping it. It was impossible for the picnic party to distinguish the occupants of the carriage. The countess’s back was turned toward the equipage. She did not look around. Mollie and Ruth were glad that she did not turn, for they recognized the two foreigners who had frightened the young Countess Sophia in the tea garden the afternoon before.

The men drove up to a palm tree near the spot where Mr. Stuart’s guests were eating. They hitched their horse. Then they walked deliberately over to the picnickers. Without a word one of the men reached down. He touched the Countess Sophia von Stolberg on the arm.

Undoubtedly he was German. His face looked threatening and his manner was insulting. His companion waited near him. The Countess Sophia shuddered as the stranger touched her. She trembled and turned pale like a frightened child.

“Madame,” said the German, “you are wanted by the police. We have been sent to arrest you.”

Mrs. De Lancey Smythe gave a hysterical laugh of triumph.

But the young countess quickly recovered her self-control.

“You have made a mistake,” she returned quietly, to the man, whose hand still rested on her arm. “What have I done to be arrested? You have no right to annoy me.”

“You are the notorious swindler wanted by the police of two continents,” accused the German. “I am here to take you back to France where you are wanted.”
