“You spoke of some bones, Mr. Mason. Could you show them before you go?”

“They are here in this corner.” The trainer strode across and then stood in silent surprise as our light was turned upon the place. “They are gone,” said he.

“So I expected,” said Holmes, chuckling. “I fancy the ashes of them might even now be found in that oven which had already consumed a part.”

“But why in the world would anyone want to burn the bones of a man who has been dead a thousand years?” asked John Mason.

“That is what we are here to find out,” said Holmes. “It may mean a long search, and we need not detain you. I fancy that we shall get our solution before morning.”

When John Mason had left us, Holmes set to work making a very careful examination of the graves, ranging from a very ancient one, which appeared to be Saxon, in the centre, through a long line of Norman Hugos and Odos, until we reached the Sir William and Sir Denis Falder of the eighteenth century. It was an hour or more before Holmes came to a leaden coffin standing on end before the entrance to the vault. I heard his little cry of satisfaction and was aware from his hurried but purposeful movements that that he had reached a goal. With his lens he was eagerly examining the edges of the heavy lid. Then he drew from his pocket a short jemmy, a box-opener, which he thrust into a chink, levering back the whole front, which seemed to be secured by only a couple of clamps. There was a rending, tearing sound as it gave way, but it had hardly hinged back and partly revealed the contents before we had an unforeseen interruption.

Someone was walking in the chapel above. It was the firm, rapid step of one who came with a definite purpose and knew well the ground upon which he walked. A light streamed down the stairs, and an instant later the man who bore it was framed in the Gothic archway. He was a terrible figure, huge in stature and fierce in manner. A large stable-lantern which he held in front of him shone upward upon a strong, heavily moustached face and angry eyes, which glared round him into every recess of the vault, finally fixing themselves with a deadly stare upon my companion and myself.

“Who the devil are you?” he thundered. “And what are you doing upon my property?” Then, as Holmes returned no answer he took a couple of steps forward and raised a heavy stick which he carried. “Do you hear me?” he cried. “Who are you? What are you doing here?” His cudgel quivered in the air.

But instead of shrinking Holmes advanced to meet him.

“I also have a question to ask you, Sir Robert,” he said in his sternest tone. “Who is this? And what is it doing here?”

He turned and tore open the coffin-lid behind him. In the glare of the lantern I saw a body swathed in a sheet from head to foot with dreadful, witch-like features, all nose and chin, projecting at one end, the dim, glazed eyes staring from a discoloured and crumbling face.

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... "
