Aramis uttered a cry of joy.

Athos stepped back and passed his hand across his brow.

"Fatality!" he muttered.

68. Cromwell's House.

It was, in fact, Mordaunt whom D'Artagnan had followed, without knowing
it. On entering the house he had taken off his mask and imitation beard,
then, mounting a staircase, had opened a door, and in a room lighted
by a single lamp found himself face to face with a man seated behind a
desk.

This man was Cromwell.

Cromwell had two or three of these retreats in London, unknown except to
the most intimate of his friends. Mordaunt was among these.

"It is you, Mordaunt," he said. "You are late."

"General, I wished to see the ceremony to the end, which delayed me."

"Ah! I scarcely thought you were so curious as that."

"I am always curious to see the downfall of your honor's enemies, and
he was not among the least of them. But you, general, were you not at
Whitehall?"

"No," said Cromwell.

There was a moment's silence.

"Have you had any account of it?"

"None. I have been here since the morning. I only know that there was a
conspiracy to rescue the king."

"Ah, you knew that?" said Mordaunt.

"It matters little. Four men, disguised as workmen, were to get the king

"But--if the plot had succeeded?"

"I wished it to do so."

"I thought your excellence considered the death of Charles I. as a
misfortune necessary to the welfare of England."

"Yes, his death; but it would have been more seemly not upon the
scaffold."

"Why so?" asked Mordaunt.

Cromwell smiled. "Because it could have been said that I had had him
condemned for the sake of justice and had let him escape out of pity."

"But if he had escaped?"

"Impossible; my precautions were taken."

"And does your honor know the four men who undertook to rescue him?"

"The four Frenchmen, of whom two were sent by the queen to her husband
and two by Mazarin to me."

"And do you think Mazarin commissioned them to act as they have done?"

"It is possible. But he will not avow it."

"How so?"

"Because they failed."

"Your honor gave me two of these Frenchmen when they were only guilty of
fighting for Charles I. Now that they are guilty of a conspiracy against
