The Growler and the Masher were waiting for him in the drawing-room of the Hotel Franklin, a small family-hotel near the Trocadero. Mme. Mergy had not yet written to him.

"Oh," he said, "I can trust her! She will hang on to Daubrecq until she is certain."

However, toward the end of the afternoon, he began to grow impatient and anxious. He was fighting one of those battles - the last, he hoped - in which the least delay might jeopardize everything. If Daubrecq threw Mme. Mergy off the scent, how was he to be caught again? They no longer had weeks or days, but only a few hours, a terribly limited number of hours, in which to repair any mistakes that they might commit.

He saw the proprietor of the hotel and asked him:

"Are you sure that there is no express letter for my two friends?"

"Quite sure, sir."

"Nor for me, M. Nicole?"

"No, sir."

"That's curious," said Lupin. "We were certain that we should hear from Mme. Audran."

Audran was the name under which Clarisse was staying at the hotel.

"But the lady has been," said the proprietor.

"What's that?"

"She came some time ago and, as the gentlemen were not there, left a letter in her room. Didn't the porter tell you?"

Lupin and his friends hurried upstairs. There was a letter on the table.

"Hullo!" said Lupin. "It's been opened! How is that? And why has it een cut about with scissors?"

The letter contained the following lines:

"Daubrecq has spent the week at the Hotel Central. This morning he had his luggage taken to the Gare de --- and telephoned to reserve a berth in the sleeping-car --- for ---

"I do not know when the train starts. But I shall be at the station all the afternoon. Come as soon as you can, all three of you. We will arrange to kidnap him."

"What next?" said the Masher. "At which station? And where's the sleeping-car for? She has cut out just the words we wanted!"

"Yes," said the Growler. "Two snips with the scissors in each place; and the words which we most want are gone. Who ever saw such a thing? Has Mme. Mergy lost her head?"

Lupin did not move. A rush of blood was beating at his temples with such violence that he glued his fists to them and pressed with all his might. His fever returned, burning and riotous, and his will, incensed to the verge of physical suffering, concentrated itself upon that stealthy enemy, which must be controlled then and there, if he himself did not wish to be irretrievably beaten.

He muttered, very calmly:

"Daubrecq has been here."

"Daubrecq!"

"We can't suppose that Mme. Mergy has been amusing herself by cutting out those two words. Daubrecq has been here. Mme. Mergy thought that she was watching him. He was watching her instead."

"How?"

"Doubtless through that hall-porter who did not tell us that Mme. Mergy had been to the hotel, but who must have told Daubrecq. He came. He read the letter. And, by way of getting at us, he contented himself with cutting out the essential words."

"We can find out... we can ask... "
