Sholmes handed the porter a piece of fifty centimes.

“Thank you, Monsieur Sholmes,” said the porter.

The Englishman looked at him; it was Arsène Lupin.

“You!... you!” he stammered, absolutely astounded.

And Wilson brandished his sound arm in the manner of a man who demonstrates a fact as he said:

“You! you! but you were arrested! Sholmes told me so. When he left you Ganimard and thirty men had you in charge.”

Lupin folded his arms and said, with an air of indignation:

“Did you suppose I would let you go away without bidding you adieu? After the very friendly relations that have always existed between us! That would be discourteous and ungrateful on my part.”

The train whistled. Lupin continued:

“I beg your pardon, but have you everything you need? Tobacco and matches ... yes ... and the evening papers? You will find in them an account of my arrest—your last exploit, Monsieur Sholmes. And now, au revoir. Am delighted to have made your acquaintance. And if ever I can be of any service to you, I shall be only too happy....” He leaped to the platform and closed the door.
