"What has become of Danglars, the instigator, and therefore the most guilty?"

"What has become of him? Why, he left Marseilles, and was taken, on the recommendation of M. Morrel, who did not know his crime, as cashier into a Spanish bank. During the war with Spain he was employed in the commissariat of the French army, and made a fortune; then with that money he speculated in the funds, and trebled or quadrupled his capital; and, having first married his banker's daughter, who left him a widower, he has married a second time, a widow, a Madame de Nargonne, daughter of M. de Servieux, the king's chamberlain, who is in high favor at court. He is a millionaire, and they have made him a baron, and now he is the Baron Danglars, with a fine residence in the Rue de Mont-Blanc, with ten horses in his stables, six footmen in his ante-chamber, and I know not how many millions in his strongbox."

"Ah!" said the abbe, in a peculiar tone, "he is happy."

"Happy? Who can answer for that? Happiness or unhappiness is the secret known but to one's one self and the walls -- walls have ears but no tongue; but if a large fortune produces happiness, Danglars is happy."

"And Fernand?"

"Fernand? Why, much the same story."

"But how could a poor Catalan fisher-boy, without education or resources, make a fortune? I confess this staggers me."

"And it has staggered everybody. There must have been in his life some strange secret that no one knows."

"But, then, by what visible steps has he attained this high fortune or high position?"

"Both, sir -- he has both fortune and position -- both."

"This must be impossible!"

"It would seem so; but listen, and you will understand. Some days before the return of the emperor, Fernand was drafted. The Bourbons left him quietly enough at the Catalans, but Napoleon returned, a special levy was made, and Fernand was compelled to join. I went too; but as I was older than Fernand, and had just married my poor wife, I was only sent to the coast. Fernand was enrolled in the active troop, went to the frontier with his regiment, and was at the battle of Ligny. The night after that battle he was sentry sentry at the door of a general who carried on a secret correspondence with the enemy. That same night the general was to go over to the English. He proposed to Fernand to accompany him; Fernand agreed to do so, deserted his post, and followed the general. Fernand would have been court-martialed if Napoleon had remained on the throne, but his action was rewarded by the Bourbons. He returned to France with the epaulet of sub-lieutenant, and as the protection of the general, who is in the highest favor, was accorded to him, he was a captain in 1823, during the Spanish war -- that is to say, at the time when Danglars made his early speculations. Fernand was a Spaniard, and being sent to Spain to ascertain the feeling of his fellow-countrymen, found Danglars there, got on very intimate terms with him, won over the support of the royalists at the capital and in the provinces, received promises and made pledges on his own part, guided his regiment by paths known to himself alone through the mountain gorges which were held by the royalists, and, in fact, rendered such services in this brief campaign that, after the taking of Trocadero, he was made colonel, and received the title of count and the cross of an officer of the Legion of Honor."

Our hope was that, by taking train, we might get to Beckenham as soon as or sooner than the carriage. On reaching Scotland Yard, however, it was more than an hour before we could get Inspector Gregson and comply with the legal formalities which would enable us to enter the house. It was a quarter to ten before we reached London Bridge, and half past before the four of us alighted on the Beckenham platform. A drive of half a mile brought us to The Myrtles — a large, dark house standing back from the road in its own grounds. Here we dismissed our cab and made our way up the drive together.

“The windows are all dark,” remarked the inspector. “The house seems deserted.”

“Our birds are flown and the nest empty,” said Holmes.

“Why do you say so?”

“A carriage heavily loaded with luggage has passed out during the last hour.”

The inspector laughed. “I saw the wheel-tracks in the light of the gate-lamp, but where does the luggage come in?”

“You may have observed the same wheel-tracks going the other way. But the outward-bound ones were very much deeper — so much so that we can say for a certainty that there was a very considerable weight on the carriage.”

“You get a trifle beyond me there,” said the inspector, shrugging his shoulders. “It will not be an easy door to force, but we will try if we cannot make someone hear us.”

He hammered loudly at the knocker and pulled at the bell, but without any success. Holmes had slipped away, but he came back in a few minutes.

“I have a window open,” said he.

“It is a mercy that you are on the side of the force, and not against it, Mr. Holmes,” remarked the inspector as he noted the clever way in which my friend had forced back the catch. “Well, I think that under the circumstances we may enter without an invitation.”

One after the other we made our way into a large apartment, which was evidently that in which Mr. Melas had found himself. The inspector had lit his lantern, and by its light we could see the two doors, the curtain, the lamp, and the suit of Japanese mail as he had described them. On the table lay two glasses, an empty brandy-bottle, and the remains of a meal.

“What is that?” asked Holmes suddenly.

We all stood still and listened. A low moaning sound was coming from somewhere over our heads. Holmes rushed to the door and out into the hall. The dismal noise came from upstairs. He dashed up, the inspector and I at his heels, while his brother Mycroft followed as quickly as his great bulk would permit.

Three doors faced us upon the second floor, and it was from the central of these that the sinister sounds were issuing, sinking sometimes into a dull mumble and rising again into a shrill whine. It was locked, but the key had been left on the outside. Holmes flung open the door and rushed in, but he was out again in an instant, with his hand to his throat.

“It’s charcoal,” he cried. “Give it time. It will clear.”
