Night fell as they journeyed on, ever joined by fresh contingents from all the country round.  In the van pressed forward the folk of Saint Philbert, warm from the utter destruction of the house of the witch woman, La Meffraye, so that not one stone was left upon another.  Guided by these the Duke and his party made their way easily through the forest, even in the darkness of the night.  And as they passed hamlet or cottage ever and anon some frenzied mother would rush upon them and fall on her knees before the Duke, praying him to look well for her darling, and bringing mayhap some pitiful shred of clothing or lock of hair by which the searchers might identify the lost innocent.

As they went forward the soldiers pricked on ahead, and caused the people to fall to the rear, lest any foreknowledge of their purpose might reach the wizard and warn him to escape.

The woods of Machecoul were dark and silent that night.  Not the howl of a questing wolf was heard.  Truly the marshal’s demons had forsaken him, or mayhap they were all busy at that last carnival in the keep of the Castle of Machecoul.

As the storming party approached nearer, and while yet they were several miles distant, they became aware of a great red light that gleamed forth above them.  They could not see whence it came, but the peasants of Saint Philbert with affrighted glances told how it beaconed only after the disappearance of some little one from their homes, what strange cries were heard ringing out from that lofty tower, and how for days after the smoke of a great burning would hang about the gloomy turrets of devil-haunted Machecoul.

Fiercer and ever fiercer shone the red glare, and the faces of the soldiers were lit up so that Pierre de l’Hopital ordered them to keep to the more gloomy arcades of the forest.

Then by midnight the cordon was drawn so closely that none might pass in or out.  And behind the soldiery the common folk lay crouched, anger in their hearts, and their eyes turned towards the open windows in the keep of Machecoul, from which flared the red light of bale.

Then, covering their lanterns, the three Scots, with Duke John, Pierre de l’Hopital, and a score of officers, stole silently towards the tower by which the Lady Sybilla had promised that an entrance should be gained to the Castle of Machecoul.

It was situated at the western corner towards the south, and was joined to its fellows at the corresponding angles of the fortress by galleried walls of great height.  Ten feet above the ground was a little door of embossed iron, but ordinarily no steps led to it when the castle was in a state of defence.  Yet when Sholto adventured into the angle of the wall, he stumbled upon a ladder that leaned against the little landing-ledge, above which was the entrance denoted on the plan.

Sholto ascended first, being the lightest and most agile of all.  As he had expected, he found the door unlocked and a narrow passage leading within the tower.  He lay a moment and listened, and then, being certain there was a light and the sounds of labour within, he crawled back to the ladder head, and whispered to the Lord James an order for total silence.
