The room, as I gazed round, was a most singular mixture of dates and of places. The half-panelled walls may well have belonged to the original yeoman farmer of the seventeenth century. They were ornamented, however, on the lower part by a line of well-chosen modern water-colours; while above, where yellow plaster took the place of oak, there was hung a fine collection of South American utensils and weapons, which had been brought, no doubt, by the Peruvian lady upstairs. Holmes rose, with that quick curiosity which sprang from his eager mind, and examined them with some care. He returned with his eyes full of thought.

“Hullo!” he cried. “Hullo!”

A spaniel had lain in a basket in the corner. It came slowly forward towards its master, walking with difficulty. Its hind legs moved irregularly and its tail was on the ground. It licked Ferguson’s hand.

“What is it, Mr. Holmes?”

“The dog. What’s the matter with it?”

“That’s what puzzled the vet. A sort of paralysis. Spinal meningitis, he thought. But it is passing. He’ll be all right soon — won’t you, Carlo?”

A shiver of assent passed through the drooping tail. The dog’s mournful eyes passed from one of us to the other. He knew that we we were discussing his case.

“Did it come on suddenly?”

“In a single night.”

“How long ago?”

“It may have been four months ago.”

“Very remarkable. Very suggestive.”

“What do you see in it, Mr. Holmes?”

“A confirmation of what I had already thought.”

“For God’s sake, what do you think, Mr. Holmes? It may be a mere intellectual puzzle to you, but it is life and death to me! My wife a would-be murderer — my child in constant danger! Don’t play with me, Mr. Holmes. It is too terribly serious.”

The big Rugby three-quarter was trembling all over. Holmes put his hand soothingly upon his arm.

“I fear that there is pain for you, Mr. Ferguson, whatever the solution may be,” said he. “I would spare you all I can. I cannot say more for the instant, but before I leave this house I hope I may have something definite.”

“Please God you may! If you will excuse me, gentlemen, I will go up to my wife’s room and see if there has been any change.”

He was away some minutes, during which Holmes resumed his examination of the curiosities upon the wall. When our host returned it was clear from his downcast face that he had made no progress. He brought with him a tall, slim, brown-faced girl.

“The tea is ready, Dolores,” said Ferguson. “See that your mistress has everything she can wish.”

“She verra ill,” cried the girl, looking with indignant eyes at her master. “She no ask for food. She verra ill. She need doctor. I frightened stay alone with her without doctor.”

Ferguson looked at me with a question in his eyes.

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... "
