“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 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 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.

"Perhaps I'm in the way?" Lupin suggested.

"Not at all, doctor, not at all," said Daubrecq. "Besides, what I have to say has a certain bearing on your errand." And, into the telephone, "Hullo! M. Prasville?... Ah, it's you, Prasville, old cock!... Why, you seem quite staggered! Yes, you're right, it's an age since you and I met. But, after all, we've never been far away in thought... And I've had plenty of visits from you and your henchmen... In my absence, it's true. Hullo!... What?... Oh, you're in a hurry? I beg your pardon!... So am I, for that matter... Well, to come to the point, there's a little service I want to do you... Wait, can't you, you brute?... You won't regret it... It concerns your renown... Hullo!... Are you listening?... Well, take half-a-dozen men with you... plain-clothes detectives, by preference: you'll find them at the night-office... Jump into a taxi, two taxis, and come along here as fast as you can... I've got a rare quarry for you, old chap. One of the upper ten... a lord, a marquis Napoleon himself... in a word, Arsene Lupin!"

Lupin sprang to his feet. He was prepared for everything but this. Yet something within him stronger than astonishment, an impulse of his whole nature, made him say, with a laugh:

"Oh, well done, well done!"

Daubrecq bowed his head, by way of thanks, and muttered:

"I haven't quite finished... A little patience, if you don't mind." And he continued, "Hullo! Prasville!... No, no, old chap, I'm not humbugging... You'll find Lupin here, with me, in my study... Lupin, who's worrying me like the rest of you... Oh, one more or less makes no difference to me! But, all the same, this one's a bit too pushing. And I am appealing to your sense of kindness. Rid me of the fellow, do... Half-a-dozen of your satellites and the two who are pacing up and down outside my house will be enough... Oh, while you're about it, go up to the third floor and rope in my cook as well... She's the famous Victoire: you know, Master Lupin's old nurse... And, look here, one more tip, to show you how I love you: send a squad of men to the Rue Chateaubriand, at the corner of the Rue Balzac... That's where our national hero lives, under the name of Michel Beaumont... Do you twig, old cockalorum? And now to business. Hustle!"

When Daubrecq turned his head, Lupin was standing up, with clenched fists. His burst of admiration had not survived the rest of the speech and the revelations which Daubrecq had made about Victoire and the flat in the Rue Chateaubriand. The humiliation was too great; and Lupin no longer bothered to play the part of the small general practitioner. He had but one idea in his head: not to give way to the tremendous fit of rage that was urging him to rush at Daubrecq like a bull.

Daubrecq gave the sort of little cluck which, with him, did duty for a laugh. He came waddling up, with his hands in his trouser-pockets, and said, incisively:

"Don't you think that this is all for the best? I've cleared the ground, relieved the situation... At least, we now know where we stand. Lupin versus Daubrecq; and that's all about it. Besides, think of the time saved! Dr. Vernes, the divisional surgeon, would have taken two hours to spin his yarn! Whereas, like this, Master Lupin will be compelled to get his little story told in thirty minutes... unless he wants to get himself collared and his accomplices nabbed. What a shock! What a bolt from the blue! Thirty minutes and not a minute more. In thirty minutes from now, you'll have to clear out, scud away like a hare and beat a disordered retreat. Ha, ha, ha, what fun! I say, Polonius, you really are unlucky, each time you come up against Bibi Daubrecq! For it was you who were hiding behind that curtain, wasn't it, my ill-starred Polonius?"
