"Just so. The explosion would have done what the axe had failed to do. Men would have said that the king had escaped human justice and been overtaken by God's. You see now why I did not care to know your gentleman in the mask; for really, in spite of his excellent intentions, I could not thank him for what he has done."
Mordaunt bowed humbly. "Sir," he said, "you are a profound thinker and your plan was sublime."
"Say absurd, since it has become useless. The only sublime ideas in politics are those which bear fruit. So to-night, Mordaunt, go to Greenwich and ask for the captain of the felucca Lightning. Show him a white handkerchief knotted at the four corners and tell the crew to disembark and carry the powder back to the arsenal, unless, indeed ---- "
"Unless?" said Mordaunt, whose face was lighted by a savage joy as Cromwell spoke:
"This skiff might be of use to you for personal projects."
"Oh, my lord, my lord!"
"That title," said Cromwell, laughing, "is all very well here, but take care a word like that does not escape your lips in public."
"But your honor will soon be called so generally."
"I hope so, at least," said Cromwell, rising and putting on his cloak.
"You are going, sir?"
"Yes," said Cromwell. "I slept here last night and the night before, and you know it is not my custom to sleep three times in the same bed."
"Then," said Mordaunt, "your honor gives me my liberty for to-night?"
"And even for all day to-morrow, if you want it. Since last evening," he added, smiling, "you have done enough in my service, and if you have any personal matters to settle it is just that I should give you time."
"Thank you, sir; it will be well employed, I hope."
Cromwell turned as he was going.
"Are you armed?" he asked.
"I have my sword."
"And no one waiting for you outside?"
"No."
"Then you had better come with me."
"Thank you, sir, but the way by the subterranean passage would take too much time and I have none to lose."
Cromwell placed his hand on a hidden handle and opened a door so well concealed by the tapestry that the most practiced eye could not have discovered it. It closed after him with a spring. This door communicated with a subterranean passage, leading under the street to a grotto in the garden of a house about a hundred yards from that of the future Protector.
It was just before this that Grimaud had perceived the two men seated together.
D'Artagnan was the first to recover from his surprise.
"Mordaunt," he cried. "Ah! by Heaven! it is God Himself who sent us here."
"Yes," said Porthos, "let us break the door in and fall upon him."
"No," replied D'Artagnan, "no noise. Now, Grimaud, you come here, climb up to the window again and tell us if Mordaunt is alone and whether he is preparing to go out or go to bed.
If he comes out we shall catch him. If he stays in we will break in the window. It is easier and less noisy than the door."
Grimaud began to scale the wall again.
"Keep guard at the other door, Athos and Aramis. Porthos and I will stay here."
The friends obeyed.
"He is alone," said Grimaud.
"We did not see his companion come out."
"He may have gone by the other door."
"What is he doing?"
"Putting on his cloak and gloves."
"He's ours," muttered D'Artagnan.
Porthos mechanically drew his dagger from the scabbard.
"Put it up again, my friend," said D'Artagnan. "We must proceed in an orderly manner."
"Hush!" said Grimaud, "he is coming out. He has put out the lamp, I can see nothing now."
"Get down then and quickly."
Grimaud leaped down. The snow deadened the noise of his fall.
"Now go and tell Athos and Aramis to stand on each side of the door and clap their hands if they catch him. We will do the same."
The next moment the door opened and Mordaunt appeared on the threshold, face to face with D'Artagnan. Porthos clapped his hands and the other two came running around. Mordaunt was livid, but he uttered no cry nor called for assistance.
D'Artagnan quietly pushed him in again, and by the light of a lamp on the staircase made him ascend the steps backward one by one, keeping his eyes all the time on Mordaunt's hands, who, however, knowing that it was useless, attempted no resistance. At last they stood face to face in the very room where ten minutes before Mordaunt had been talking to Cromwell.
Porthos came up behind, and unhooking the lamp on the staircase relit that in the room. Athos and Aramis entered last and locked the door behind them.
"Oblige me by taking a seat," said D'Artagnan, pushing a chair toward Mordaunt, who sat down, pale but calm. Aramis, Porthos and D'Artagnan drew their chairs near him. Athos alone kept away and sat in the furthest corner of the room, as if determined to be merely a spectator of the proceedings. He seemed to be quite overcome. Porthos rubbed his hands in feverish impatience. Aramis bit his lips till the blood came.
D'Artagnan alone was calm, at least in appearance.
"Monsieur Mordaunt," he said, "since, after running after one another so long, chance has at last brought us together, let us have a little conversation, if you please."
