Colonel John suspected that this might be so. And his heart beat, as has been hinted, more quickly. At the evening meal he was early in the room, on the chance that she might appear before the others. But she did not descend, and the meal proved unpleasant beyond the ordinary, James drinking more than was good for him, and taking a tone, brutal and churlish, if not positively hostile. For some reason, the Colonel reflected, the young man was beginning to lose his fears. Why? What was he planning? How was he, even if he had no respect for his oath, thinking to evade that dilemma which ensured his guest's safety?

"Secure as I seem, I must look to myself," Colonel John thought. And he slept that night with his door bolted and a loaded pistol under his pillow. Next morning he took care to descend early, on the chance of seeing Flavia before the others appeared. She was not down: he waited, and she did not come. But neither did his watchers; and when he had been in the room five minutes a serving-girl slipped in at the back, showed him a scared face, held out a scrap of paper and, when he had taken it, fled in a panic and without a spoken word.

He hid the paper about him and read it later. The message was in Flavia's hand; he had seen her write more than once. But if he had not, he knew that neither James nor the O'Beirnes were capable of penning a grammatical sentence. Colonel John's spirits rose as he read the note.

"Be at the old Tower an hour after sunset. You must not be followed."

"That is more easily said than done," he commented.

Nor, if he were followed through the day as closely as on previous days, did he see how it was to be done. He stood, cudgelling his brains to evolve a plan that would enable him to give the slip to the three men and to the servants who replaced them when they were called away. But he found none that might not, by awakening James's suspicions, make matters worse; indeed, it seemed to him that James was already suspicious. He had at last to let things take their course, in the hope that when the time came they would shape themselves favourably.

They did. For before noon he gathered that James wanted to go fishing. The O'Beirnes also wanted to go fishing, and for the general convenience it became him to go with them. He said neither No nor Yes; but he dallied with the idea until it was time to start and they had made up their minds that he was coming. Then he declined.

James swore, the O'Beirnes scowled at him and grumbled. Presently the three went outside and held a conference. His hopes rose as he sat smiling to himself, for their next step was to call Darby. Evidently they gave him orders and left him in charge, for a few minutes later they went off, spending their anger on one another, and on the barefoot gossoons who carried the tackle.

Late in the afternoon Colonel John took up his position on the horse-block by the entrance-gates, where the June sun fell on him; there he affected to be busy plaiting horse-hair lines. Every two or three minutes Darby showed himself at the door: once in a quarter of an hour the old man found occasion to cross the court to count the ducks or rout a trespassing beggar. Towards sunset, however, he came less often, having to busy himself with the evening meal. The Colonel smiled and waited, and presently the butler came again, found him still seated there, and withdrew—this time with an air of finality. "He's satisfied," the Colonel muttered, and the next moment—for the sun had already set a full hour—he was gone also. The light was waning fast, night was falling in the valley. Before he had travelled a hundred yards he was lost to view.

The fishing-party had started the contrary way, so that he had nothing to fear from them. But that he might omit no precaution, when he had gone a quarter of a mile he halted and listened, with his ear near the ground, for the beat of pursuing footsteps. He heard none, nor any sounds but the low of a cow whose calf was being weaned, the "Whoo! hoo! hoo!" of owls beginning to mouse beside the lake, and the creak of oars in a boat which darkness already hid. He straightened himself with a sigh of relief, and hastened at speed in the direction of the waterfall.
