The remainder were soldiers, simple murderers' tools, who did not even know what was afoot.

Darnley reserved it for himself to appoint the time.
Two days after these conditions were agreed upon, Darnley having been notified that the queen was alone with Rizzio, wished to make himself sure of the degree of her favour enjoyed by the minister.

He accordingly went to her apartment by a little door of which he always kept the key upon him; but though the key turned in the lock, the door did not open.
Then Darnley knocked, announcing himself; but such was the contempt into which he had fallen with the queen, that Mary left him outside, although, supposing she had been alone with Rizzio, she would have had time to send him away.

Darnley, driven to extremities by this, summoned Morton, Ruthven, Lennox, Lindley, and Douglas's bastard, and fixed the assassination of Rizzio for two days later.
They had just completed all the details, and had, distributed the parts that each must play in this bloody tragedy, when suddenly, and at the moment when they least expected it, the door opened and, Mary Stuart appeared on the threshold.
"My lords," said she, "your holding these secret counsels is useless.
I am informed of your plots, and with God's help I shall soon apply a remedy".
With these words, and before the conspirators hid had time to collect themselves, she shut the door again, and vanished like a passing but threatening vision.

All remained thunderstruck.
