"Yes," replied the third officer. "I think I've got all there is to be got out of them, so I sent the people away."

"Did Mary Cregan give evidence?" asked Morton, with a frown that looked a little heavier than usual.

"No, but her master did," answered the man called Wilson, who had flat, red hair and a plain, pale face, not without sharpness. "I think he's hanging round the girl himself and is out against a rival. There's always some reason of that sort when we are told the truth about anything. And you bet the other girl told right enough."

"Well, let's hope they'll be some sort of use," remarked Nolan, in a somewhat hopeless manner, gazing out into the darkness.

"Anything is to the good," said Morton, "that lets us know anything about him."

"Do we know anything about him?" asked the melancholy Irishman.

"We know one thing about him," said Wilson, "and it's the one thing that n.o.body ever knew before. We know where he is."

"Are you sure?" inquired Morton, looking at him sharply.

"Quite sure," replied his a.s.sistant. "At this very minute he is in that tower over there by the sh.o.r.e. If you go near enough you'll see the candle burning in the window."

As he spoke the noise of a horn sounded on the road outside, and a moment after they heard the throbbing of a motor car brought to a standstill before the door. Morton instantly sprang to his feet.

"Thank the Lord that's the car from Dublin," he said. "I can't do anything without special authority, not if he were sitting on the top of the tower and putting out his tongue at us. But the chief can do what he thinks best."

He hurried out to the entrance and was soon exchanging greetings with a big handsome man in a fur coat, who brought into the dingy little station the indescribable glow of the great cities and the luxuries of the great world.

For this was Sir Walter Carey, an official of such eminence in Dublin Castle that nothing short of the case of Prince Michael would have brought him on such a journey in the middle of the night. But the case of Prince Michael, as it happened, was complicated by legalism as well as lawlessness. On the last occasion he had escaped by a forensic quibble and not, as usual, by a private escapade; and it was a question whether at the moment he was amenable to the law or not. It might be necessary to stretch a point, but a man like Sir Walter could probably stretch it as far as he liked.

Whether he intended to do so was a question to be considered.

Despite the almost aggressive touch of luxury in the fur coat, it soon became apparent that Sir Walter's large leonine head was for use as well as ornament, and he considered the matter soberly and sanely enough. Five chairs were set round the plain deal table, for who should Sir Walter bring with him but his young relative and secretary, Horne Fisher. Sir Walter listened with grave attention, and his secretary with polite boredom, to the string of episodes by which the police had traced the flying rebel from the steps of the hotel to the solitary tower beside the sea. There at least he was cornered between the moors and the breakers; and the scout sent by Wilson reported him as writing under a solitary candle, perhaps composing another of his tremendous proclamations. Indeed, it would have been typical of him to choose it as the place in which finally to turn to bay. He had some remote claim on it, as on a family castle; and those who knew him thought him capable of imitating the primitive Irish chieftains who fell fighting against the sea.

"I saw some queer-looking people leaving as I came in," said Sir Walter Carey. "I suppose they were your witnesses. But why do they turn up here at this time of night?"

Morton smiled grimly. "They come here by night because they would be dead men if they came here by day. They are criminals committing a crime that is more horrible here than theft or murder."

"What crime do you mean?" asked the other, with some curiosity.

"They are helping the law," said Morton.

There was a silence, and Sir Walter considered the papers before him with an abstracted eye. At last he spoke.

"Quite so; but look here, if the local feeling is as lively as that there are a good many points to consider. I believe the new Act will enable me to collar him now if I think it best. But is it best? A serious rising would do us no good in Parliament, and the government has enemies in England as well as Ireland. It won't do if I have done what looks a little like sharp practice, and then only raised a revolution."

"It's all the other way," said the man called Wilson, rather quickly. "There won't be half so much of a revolution if you arrest him as there will if you leave him loose for three days longer. But, anyhow, there can't be anything nowadays that the proper police can't manage."

"Mr. Wilson is a Londoner," said the Irish detective, with a smile.

"Yes, I'm a c.o.c.kney, all right," replied Wilson, "and I think I'm all the better for that. Especially at this job, oddly enough."

Sir Walter seemed slightly amused at the pertinacity of the third officer, and perhaps even more amused at the slight accent with which he spoke, which rendered rather needless his boast about his origin.

"Do you mean to say," he asked, "that you know more about the business here because you have come from London?"

"Sounds funny, I know, but I do believe it," answered Wilson. "I believe these affairs want fresh methods. But most of all I believe they want a fresh eye."

The superior officers laughed, and the redhaired man went on with a slight touch of temper:

"Well, look at the facts. See how the fellow got away every time, and you'll understand what I mean. Why was he able to stand in the place of the scarecrow, hidden by nothing but an old hat? Because it was a village policeman who knew the scarecrow was there, was expecting it, and therefore took no notice of it. Now I never expect a scarecrow. I've never seen one in the street, and I stare at one when I see it in the field. It's a new thing to me and worth noticing. And it was just the same when he hid in the well. You are ready to find a well in a place like that; you look for a well, and so you don't see it. I don't look for it, and therefore I do look at it."

"It is certainly an idea," said Sir Walter, smiling, "but what about the balcony? Balconies are occasionally seen in London."

"But not rivers right under them, as if it was in Venice," replied Wilson.

"It is certainly a new idea," repeated Sir Walter, with something like respect. He had all the love of the luxurious cla.s.ses for new ideas. But he also had a critical faculty, and was inclined to think, after due reflection, that it was a true idea as well.

Growing dawn had already turned the window panes from black to gray when Sir Walter got abruptly to his feet. The others rose also, taking this for a signal that the arrest was to be undertaken. But their leader stood for a moment in deep thought, as if conscious that he had come to a parting of the ways.

Suddenly the silence was pierced by a long, wailing cry from the dark moors outside. The silence that followed it seemed more startling than the shriek itself, and it lasted until Nolan said, heavily:

"'Tis the banshee. Somebody is marked for the grave."

His long, large-featured face was as pale as a moon, and it was easy to remember that he was the only Irishman in the room.

"Well, I know that banshee," said Wilson, cheerfully, "ignorant as you think I am of these things. I talked to that banshee myself an hour ago, and I sent that banshee up to the tower and told her to sing out like that if she could get a glimpse of our friend writing his proclamation."

"Do you mean that girl Bridget Royce?" asked Morton, drawing his frosty brows together. "Has she turned king's evidence to that extent?"

"Yes," answered Wilson. "I know very little of these local things, you tell me, but I reckon an angry woman is much the same in all countries."

Nolan, however, seemed still moody and unlike himself. "It's an ugly noise and an ugly business altogether," he said. "If it's really the end of Prince Michael it may well be the end of other things as well. When the spirit is on him he would escape by a ladder of dead men, and wade through that sea if it were made of blood."

"Is that the real reason of your pious alarms?" asked Wilson, with a slight sneer.

The Irishman's pale face blackened with a new pa.s.sion.

"I have faced as many murderers in County Clare as you ever fought with in Clapham Junction, Mr. c.o.c.kney," he said.

"Hush, please," said Morton, sharply. "Wilson, you have no kind of right to imply doubt of your superior's conduct. I hope you will prove yourself as courageous and trustworthy as he has always been."

The pale face of the red-haired man seemed a shade paler, but he was silent and composed, and Sir Walter went up to Nolan with marked courtesy, saying, "Shall we go outside now, and get this business done?"

Dawn had lifted, leaving a wide chasm of white between a great gray cloud and the great gray moorland, beyond which the tower was outlined against the daybreak and the sea.

Something in its plain and primitive shape vaguely suggested the dawn in the first days of the earth, in some prehistoric time when even the colors were hardly created, when there was only blank daylight between cloud and clay. These dead hues were relieved only by one spot of gold--the spark of the candle alight in the window of the lonely tower, and burning on into the broadening daylight. As the group of detectives, followed by a cordon of policemen, spread out into a crescent to cut off all escape, the light in the tower flashed as if it were moved for a moment, and then went out. They knew the man inside had realized the daylight and blown out his candle.

"There are other windows, aren't there?" asked Morton, "and a door, of course, somewhere round the corner? Only a round tower has no corners."

"Another example of my small suggestion," observed Wilson, quietly.

"That queer tower was the first thing I saw when I came to these parts; and I can tell you a little more about it--or, at any rate, the outside of it. There are four windows altogether, one a little way from this one, but just out of sight. Those are both on the ground floor, and so is the third on the other side, making a sort of triangle. But the fourth is just above the third, and I suppose it looks on an upper floor."

"It's only a sort of loft, reached by a ladder, said Nolan. "I've played in the place when I was a child. It's no more than an empty sh.e.l.l." And his sad face grew sadder, thinking perhaps of the tragedy of his country and the part that he played in it.
