"Train behind in possession of the enemy," returned Jack laconically.

"Bozhe moï!" ejaculated the doctor, drawing his revolver and making for the platform.

Jack passed on, not venturing to delay even long enough to assist a lady, for whom the jump from carriage to track was somewhat difficult. She sprang down unassisted.

"Monsieur Brown, Monsieur Brown!"

Jack shivered from top to toe, and never in his life felt so much inclined to take to his heels as then. He could hardly believe he had heard aright; yet amid the bustle now filling the station he had caught the whisper of his name. On a sudden impulse he swung round.

"Monsieur Brown," said Gabriele Walewska, running up to him, "I have news for you: I have something to show you."

"Come with me, Mademoiselle," said Jack instantly. "I haven't a minute to lose."

"But Masha is here; I cannot leave her."

"For heaven's sake, Mademoiselle, climb up into this carriage. I will fetch Masha."

With anxiety tearing at his heart Jack hurried back down the train. He saw Gabriele's old nurse at the door of a carriage; she was almost the only passenger who had not yet alighted.
