THE PATH ACROSS THE MORASS.
Mike, when night fell, moved away toward the castle, which lay about a quarter of a mile from the village. Approaching to within fifty yards of the gate, he sat down to watch. About eleven o'clock he heard the creak of the gate, and presently was startled by seeing two horsemen ride past him. "They must have muffled their horses' feet," he said to himself. "They are up to no good. I wish there had only been one of them." Mike slipped off his shoes and started in pursuit, keeping just far enough behind the horsemen to enable him to observe the outline of their figures. For half a mile they proceeded quietly. Then they stopped, dismounted, removed the cloths from their horses' feet, and remounting rode forward at a gallop. Mike's old exercise as a runner now rendered him good service. He could already tell, by the direction which the horsemen were taking, that they were bearing to the east of Edinburgh, but he resolved to follow as far as possible in order to see exactly whither they went. The road, or rather track, lay across a moorland country. The ground was often deep and quaggy, and the horsemen several times checked their speed, and went at a slow walk, one advancing on foot along the track to guide the way. These halts allowed breathing time for Mike, who found it hard work to keep near them when going at full speed. At last, after riding for an hour, the horsemen halted at a solitary house on the moorland, Here several horses, held by troopers, were standing. Mike crept round to the back of the house, and looked in at the window. He saw two English officers sitting by a fire, while a light burned on a table. Mike at once recognized in one of them the dreaded General Cromwell, whom he had seen at Drogheda.
"What a fool I was," he muttered to himself, "to have come without my pistol. I would have shot him as he sits, and so wiped out Drogheda."
At the moment the door opened, and a trooper in Scotch uniform entered. "I have brought this letter," he said, "from Alan Campbell."
The general took the letter and opened it. "Campbell promises," he said to the other officer, "to open fire upon the detachment in the village with the guns of the castle as soon as we attack. One of the men who has brought this will remain here and guide our troops across the morass. He suggests that two hundred foot and as many horse should be here at eight to-morrow evening. All he stipulates for is that Colonel Furness, the Royalist who commands the enemy's detachment, shall be given over to him, he having, it seems, some enmity with Argyll. Furness? ah, that is the officer whom I sent to the Bermudas from Drogheda. We had advices of his having got away and captured a ship with other prisoners on board. A bold fellow, and a good officer, but all the more dangerous. Let Campbell do with him as he likes."
The other officer drew out an inkhorn and wrote, at Cromwell's dictation, his adherence to the terms offered by Alan Campbell. Cromwell signed the paper, and handed it to the messenger. Then the English general and his escort mounted and rode off. Campbell's retainers sat for half an hour drinking together. Then they came to the door. One mounted, and saying to the other, "I would rather have twenty-four hours' sleep such as you have before you, than have to ride back to Kirkglen to-night; the mist is setting in thickly," rode off into the darkness.
Mike kept close to him, until at last the man dismounted to follow the track where the morass was most dangerous. In an instant Mike sprang upon him and buried his dagger in his body. Without a cry the trooper fell. Mike felt in his doublet for Cromwell's letter. Placing this in his breast, he went a few paces from the path where he found that he sunk to his knees, the water being some inches deep over the bog. Then he returned, lifted the body of the trooper, carried it as far into the bog as he dared venture, and then dropped it. He placed his foot on the iron breastpiece, and pressed until the body sank in the soft ooze, and the water completely covered it. Then he went back to the horse, and taking the reins, followed the track until completely clear of the moorland country, where, mounting, he rode back to Kirkglen, and presented himself to Harry. The latter had, hours before, gone to bed, having posted strong guards around the village. He struck a light and listened to Mike's relation of what he had done, and ended by the production of the document with Cromwell's signature.
"Another debt to the Earl of Argyll," Harry said grimly. "However, although this proves the treachery of his kinsman, it does not convict Argyll himself, although the evidence is strong enough to hang any other man. Now, Leslie, what do you advise? Shall we send and seize the man left at the hut?"
"It is a doubtful question," Leslie answered, after a pause. "When Campbell finds that his messenger does not return before morning, he will like enough send others off to learn the reason why. If they find him gone, Campbell may suspect that his plan has failed and may send warning to Cromwell."
"At any rate," Harry continued, "we need not decide before morning. But at daybreak, Leslie, plant a party of men on the road and stop any horseman riding out. Let the sergeant in charge say only that he has my orders that none are to pass eastward. It would be a natural precaution to take, and when the news comes back to the castle, Campbell will not necessarily know that his scheme has been detected."
