Peter Ruff looked out into the blackness, through the glittering arc of lights, and perhaps for once he suffered his fancy to build for him visions of things that were not of earth. If so, however, it was a moment which swiftly passed. His reply was in a tone as matter of fact as his usual speech.
“Because,” he said, “I do not exactly see the end of my present expedition—I do not understand its object.”
“You have some apprehension?” she asked.
“None at all,” he answered. “Why should I? There is an unwritten bargain,” he added, a little more slowly, “to which I subscribed with our friends here, and I have certainly kept it. In fact, the balance is on my side. There is nothing for me to fear.”
The train crept into the Gare du Nord, and they passed through the usual routine of the Customs House. Then, in an omnibus, they rumbled slowly over the cobblestones, through the region of barely lit streets and untidy cafes, down the Rue Lafayette, across the famous Square and into the Rue de Rivoli.
“Our movements,” Peter Ruff remarked dryly, “are too well known for us to attempt to conceal them. We may as well stop at one of the large hotels. It will be more cheerful for you while I am away.”
They engaged rooms at the Continental. Miss Brown, whose apartments were in the wing of the hotel overlooking the gardens, ascended at once to her room. Peter Ruff, who had chosen a small suite on the other side, went into the bar for a whiskey and soda. A man touched him on the elbow.
“For Monsieur,” he murmured, and vanished.
Peter Ruff turned and opened the note. It bore a faint perfume, it had a coronet upon the flap of the envelope, and it was written in a delicate feminine handwriting.
DEAR Mr. RUFF:
