“But he took away the only thing that does me any good.”

“What’s that?”

“Cigarettes d’Auvergne.”

“I never heard of them.”

“They’re the only thing to stop it, and he took away every one I had.”

But even as he spoke Pocket remembered the cigarette he had produced from his bag, but lacked the moral courage to light, in the train. He had slipped it into one of his pockets, not back into the box. He felt for it feverishly. He gave a husky cheer as his fingers closed upon the palpable thing, and he drew forth a flattened cylinder the size of a cigarette and the colour of a cigar. The boy had to bite off both ends; the man was ready with the match. Pocket drank the crude smoke down like water, coughed horribly, drank deeper, coughed the tears into his eyes, and was comparatively cured.

“And your doctor forbids a sovereign remedy!” said his companion. “I cannot understand him, and I’m a doctor myself.” His voice and look were deliberate even for him. “My name is Baumgartner,” he added, and made a pause. “I don’t suppose you know it?”

“I’m not sure I don’t,” replied Pocket, swelling with breath and gratitude; but in truth the name seemed vaguely familiar to him.

“A schoolboy in the country,” observed Dr. Baumgartner, “is scarcely likely to have heard of me; but if you inquire here in London you will find that I am not unknown. I propose to carry you off to my house for breakfast, and a little rest. That is,” added the doctor, with his first smile, “if you will trust yourself to me first and make your inquiries later.”

Pocket scouted the notion of inquiries in an impulsive outburst; but even as he proceeded to mumble out his thanks he could not help feeling it would have been less embarrassing to know more exactly whom he was thanking and must needs accompany now. Dr. Baumgartner? Where was it he had come across that name? And when and where had anybody ever seen such a doctor as this unshaven old fellow in the cloak and hat of a conspirator by limelight?
