The queen was marrying one of her servants named Sebastian: he was an Auvergnat whom she had brought with her from France, and whom she liked very much. However, as the king sent word that he had not seen her for two days, she left the wedding towards six o'clock in the evening, and came to pay him a visit, accompanied by the Countess of Argyll and the Countess of Huntly. While she was there, Durham, in preparing his bed, set fire to his palliasse, which was burned as well as a part of the mattress; so that, having thrown them out of the window all in flames, for fear lest the fire should reach the rest of the furniture, he found himself without a bed, and asked permission to return to the town to sleep; but Darnley, who remembered his terror the night before, and who was surprised at the promptness that had made Durham throw all his bedding out of the window, begged him not to go away, offering him one of his mattresses, or even to take him into his own bed. However, in spite of this offer, Durham insisted, saying that he felt unwell, and that he should like to see a doctor the same evening. So the queen interceded for Durham, and promised Darnley to send him another valet to spend the night with him: Darnley was then obliged to yield, and, making Mary repeat that she would send him someone, he gave Durham leave for that evening. At that moment Paris; of whom the queen speaks in her letters, came in: he was a young Frenchman who had been in Scotland for some years, and who, after having served with Bothwell and Seyton, was at present with the queen. Seeing him, she got up, and as Darnley still wished to keep her--
"Indeed, my lord, it is impossible," said she, "to come and see you.
I have left this poor Sebastian's wedding, and I must return to it; for I promised to came masked to his ball."
The king dared not insist; he only reminded her of the promise that she had made to send him a servant: Mary renewed it yet once again, and went away with her attendants. As for Durham, he had set out the moment he received permission.
It was nine o'clock in the evening. Darnley, left alone, carefully shut the doors within, and retired to rest, though in readiness to rise to let in the servant who should come to spend the night with him. Scarcely was he in bed than the same noise that he had heard the night before recommenced; this time Darnley listened with all the attention fear gives, and soon he had no longer any doubt but that several men were walking about beneath him. It was useless to call, it was dangerous to go out; to wait was the only course that remained to the king. He made sure again that the doors were well fastened, put his sword under his pillow, extinguished his lamp for fear the light might betray him, and awaited in silence for his servant's arrival; but the hours passed away, and the servant did not come.
At one o'clock in the morning, Bothwell, after having talked some while with the queen, in the presence of the captain of the guard, returned home to change his dress; after some minutes, he came out wrapped up in the large cloak of a German hussar, went through the guard-house, and had the castle gate opened. Once outside, he took his way with all speed to Kirk of Field, which he entered by the opening in the wall: scarcely had he made a step in the garden than he met James Balfour, governor of the castle.
"Well," he said to him, "how far have we got?
"Everything is ready," replied Balfour, "and we were waiting for you to set fire to the fuse". "That is well," Bothwell answered--"but first I want to make sure that he is in his room."
At these words, Bothwell opened the pavilion door with a false key, and, having groped his way up the stairs; he went to listen at Darnley's door. Darnley, hearing no further noise, had ended by going to sleep; but he slept with a jerky breathing which pointed to his agitation. Little mattered it to Bothwell what kind of sleep it was, provided that he was really in his room. He went down again in silence, then, as he had come up, and taking a lantern from one of the conspirators, he went himself into the lower room to see if everything was in order: this room was full of barrels of powder, and a fuse ready prepared wanted but a spark to set the whole on fire.
Bothwell withdrew, then, to the end of the garden with Balfour, David, Chambers, and three or four others, leaving one man to ignite the fuse. In a moment this man rejoined them.
There ensued some minutes of anxiety, during which the five men looked at one another in silence and as if afraid of themselves; then, seeing that nothing exploded, Bothwell impatiently turned round to the engineer, reproaching him for having, no doubt through fear, done his work badly. He assured his master that he was certain everything was all right, and as Bothwell, impatient, wanted to return to the house himself, to make sure, he offered to go back and see how things stood. In fact, he went back to the pavilion, and, putting his head through a kind of air-hole, he saw the fuse, which was still burning. Some seconds afterwards, Bothwell saw him come running back, making a sign that all was going well; at the same moment a frightful report was heard, the pavilion was blown to pieces, the town and the firth were lit up with a clearness exceeding the brightest daylight; then everything fell back into night, and the silence was broken only by the fall of stones and joists, which came down as fast as hail in a hurricane.
Next day the body of the king was found in a garden in the neighbourhood: it had been saved from the action of the fire by the mattresses on which he was lying, and as, doubtless, in his terror he had merely thrown himself on his bed wrapped in his dressing-gown and in his slippers, and as he was found thus, without his slippers, which were flung some paces away, it was believed that he had been first strangled, then carried there; but the most probable version was that the murderers simply relied upon powder--an auxiliary sufficiently powerful in itself for them to have no fear it would fail them.
