I went on and the next letters formed two more words, which I separated as they appeared. And, to my great amazement, a complete English sentence lay before my eyes.
"Done?" asked Lupin, after a time.
"Done!.. By the way, there are mistakes in the spelling…"
"Never mind those and read it out, please… Read slowly."
Thereupon I read out the following unfinished communication, which I will set down as it appeared on the paper in front of me:
"Take no unnecessery risks. Above all, avoid atacks, approach ennemy with great prudance and…"
I began to laugh:
"And there you are! Fiat lux! We're simply dazed with light! But, after all, Lupin, confess that this advice, dribbled out by a kitchen-maid, doesn't help you much!"
Lupin rose, without breaking his contemptuous silence, and took the sheet of paper.
I remembered soon after that, at this moment, I happened to look at the clock. It was eighteen minutes past five.
Lupin was standing with the paper in his hand; and I was able at my ease to watch, on his youthful features, that extraordinary mobility of expression which baffles all observers and constitutes his great strength and his chief safeguard. By what signs can one hope to identify a face which changes at pleasure, even without the help of make-up, and whose every transient expression seems to be the final, definite expression?.. By what signs? There was one which I knew well, an invariable sign: Two little crossed wrinkles that marked his forehead whenever he made a powerful effort of concentration. And I saw it at that moment, saw the tiny tell-tale cross, plainly and deeply scored.
He put down the sheet of paper and muttered:
"Child's play!"
The clock struck half-past five.
"What!" I cried. "Have you succeeded?.. In twelve minutes?.."
He took a few steps up and down the room, lit a cigarette and said:
"You might ring up Baron Repstein, if you don't mind, and tell him I shall be with him at ten o'clock this evening."
"Baron Repstein?" I asked. "The husband of the famous baroness?"
"Yes."
"Are you serious?"
"Quite serious."
Feeling absolutely at a loss, but incapable of resisting him, I opened the telephone-directory and unhooked the receiver. But, at that moment, Lupin stopped me with a peremptory gesture and said, with his eyes on the paper, which he had taken up again:
"No, don't say anything… It's no use letting him know… There's something more urgent … a queer thing that puzzles me… Why on earth wasn't the last sentence finished? Why is the sentence…"
He snatched up his hat and stick:
"Let's be off. If I'm not mistaken, this is a business that requires immediate solution; and I don't believe I am mistaken."
He put his arm through mine, as we went down the stairs, and said:
"I know what everybody knows. Baron Repstein, the company-promoter and racing-man, whose colt Etna won the Derby and the Grand Prix this year, has been victimized by his wife. The wife, who was well known for her fair hair, her dress and her extravagance, ran away a fortnight ago, taking with her a sum of three million francs, stolen from her husband, and quite a collection of diamonds, pearls and jewellery which the Princesse de Berny had placed in her hands and which she was supposed to buy. For two weeks the police have been pursuing the baroness across France and the continent: an easy job, as she scatters gold and jewels wherever she goes. They think they have her every moment. Two days ago, our champion detective, the egregious Ganimard, arrested a visitor at a big hotel in Belgium, a woman against whom the most positive evidence seemed to be heaped up. On enquiry, the lady turned out to be a notorious chorus-girl called Nelly Darbal. As for the baroness, she has vanished. The baron, on his side, has offered a reward of two hundred thousand francs to whosoever finds his wife. The money is in the hands of a solicitor. Moreover, he has sold his racing-stud, his house on the Boulevard Haussmann and his country-seat of Roquencourt in one lump, so that he may indemnify the Princesse de Berny for her loss."
"And the proceeds of the sale," I added, "are to be paid over at once. The papers say that the princess will have her money to-morrow. Only, frankly, I fail to see the connection between this story, which you have told very well, and the puzzling sentence…"
Lupin did not condescend to reply.
We had been walking down the street in which I live and had passed some four or five houses, when he stepped off the pavement and began to examine a block of flats, not of the latest construction, which looked as if it contained a large number of tenants:
"According to my calculations," he said, "this is where the signals came from, probably from that open window."
"On the third floor?"
"Yes."
He went to the portress and asked her:
"Does one of your tenants happen to be acquainted with Baron Repstein?"
"Why, of course!" replied the woman. "We have M. Lavernoux here, such a nice gentleman; he is the baron's secretary and agent. I look after his flat."
"And can we see him?"
"See him?.. The poor gentleman is very ill."
"Ill?"
"He's been ill a fortnight … ever since the trouble with the baroness… He came home the next day with a temperature and took to his bed."
"But he gets up, surely?"
"Ah, that I can't say!"
"How do you mean, you can't say?"
"No, his doctor won't let any one into his room. He took my key from me."
"Who did?"
"The doctor. He comes and sees to his wants, two or three times a day. He left the house only twenty minutes ago … an old gentleman with a grey beard and spectacles… Walks quite bent… But where are you going sir?"
"I'm going up, show me the way," said Lupin, with his foot on the stairs. "It's the third floor, isn't it, on the left?"
"But I mustn't!" moaned the portress, running after him. "Besides, I haven't the key … the doctor…"
They climbed the three flights, one behind the other. On the landing, Lupin took a tool from his pocket and, disregarding the woman's protests, inserted it in the lock. The door yielded almost immediately. We went in.
At the back of a small dark room we saw a streak of light filtering through a door that had been left ajar. Lupin ran across the room and, on reaching the threshold, gave a cry:
"Too late! Oh, hang it all!"
The portress fell on her knees, as though fainting.
I entered the bedroom, in my turn, and saw a man lying half-dressed on the carpet, with his legs drawn up under him,
