photography has the virtue of depending on daylight. And if you don't know that I would grind all the Gothic arches in the world to powder to save the sanity of a single human soul, you don't know so much about my religion as you think you do.'
The young Australian had sprung to his feet like a man rejuvenated. 'By George! that's the talk,' he cried; 'though I never thought to hear it from that quarter. I'll tell you what, reverend sir, I'll do something that will show I haven't lost my courage after all.'
The old steward was still looking at him with quaking watchfulness, as if he felt something fey about the young man's defiance. 'Oh,' he cried, 'what are you going to do now?'
'I am going to photograph the portrait,' replied Darnaway.
Yet it was barely a week afterwards that the storm of the catastrophe seemed to stoop out of the sky, darkening that sun of sanity to which the priest had appealed in vain, and plunging the mansion once more in the darkness of the Darnaway doom. It had been easy enough to fit up the new studio; and seen from inside it looked very like any other such studio, empty except for the fullness of the white light. A man coming from the gloomy rooms below had more than normally the sense of stepping into a more than modern brilliancy, as blank as the future. At the suggestion of Wood, who knew the castle well and had got over his first aesthetic grumblings, a small room remaining intact in the upper ruins was easily turned into a dark room, into which Darnaway went out of the white daylight to grope by the crimson gleams of a red lamp. Wood said, laughing, that the red lamp had reconciled him to the vandalism; as that bloodshot darkness was as romantic as an alchemist's cave.
Darnaway had risen at daybreak on the day that he meant to photograph the mysterious portrait, and had it carried up from the library by the single corkscrew staircase that connected the two floors. There he had set it up in the wide white daylight on a sort of easel and planted his photographic tripod in front of it. He said he was anxious to send a reproduction of it to a great antiquary who had written on the antiquities of the house; but the others knew that this was an excuse covering much deeper things. It was, if not exactly a spiritual duel between Darnaway and the demoniac picture, at least a duel between Darnaway and his own doubts. He wanted to bring the daylight of photography face to face with that dark masterpiece of painting; and to see whether the sunshine of the new art would not drive out the shadows of the old.
Perhaps this was why he preferred to do it by himself, even if some of the details seemed to take longer and involve more than normal delay. Anyhow, he rather discouraged the few who visited his studio during the day of the experiment, and who found him focusing and fussing about in a very isolated and impenetrable fashion. The steward had left a meal for him, as he refused to come down; the old gentleman also returned some hours afterwards and found the meal more or less normally disposed of; but when he brought it he got no more gratitude than a grunt. Payne went up once to see how he was getting on, but finding the photographer disinclined for conversation came down again. Father Brown had wandered that way in an unobtrusive style to lake Darnaway a letter from the expert to whom the photograph was to be sent. But he left the letter on a tray, and whatever he thought of that great glasshouse full of daylight and devotion to a hobby, a world he had himself in some sense created, he kept it to himself and came down. He had reason to remember very soon that he was the last to come down the solitary staircase connecting the floors, leaving a lonely man and an empty room behind him. The others were standing in the salon that led into the library, just under the great black ebony clock that looked like a titanic coffin.
'How was Darnaway getting on,' asked Payne, a little later, 'when you last went up?'
The priest passed a hand over his forehead. 'Don't tell me I'm getting psychic,' he said with a sad smile. 'I believe I'm quite dazzled with daylight up in that room and couldn't see things straight. Honestly, I felt for a flash as if there were something uncanny about Darnaway's figure standing before that portrait.'
'Oh, that's the lame leg,' said Barnet promptly. 'We know all about that.'
'Do you know,' said Payne abruptly, but lowering his voice, 'l don't think we do know all about it or anything about it. What's the matter with his leg? What was the matter with his ancestor's leg?'
'Oh, there's something about that in the book I was reading in there, in the family archives,' said Wood; 'I'll fetch it for you.' And he stepped into the library just beyond.
'I think,' said Father Brown quietly, 'Mr Payne must have some particular reason for asking that.'
'I may as well blurt it out once and for all,' said Payne, but in a yet lower voice. 'After all, there is a rational explanation. A man from anywhere might have made up to look like the portrait. What do we know about Darnaway? He is behaving rather oddly–'
The others were staring at him in a rather startled fashion; but the priest seemed to take it very calmly.
'I don't think the old portrait's ever been photographed,' he said. 'That's why he wants to do it. I don't think there's anything odd about that.'
'Quite an ordinary state of things, in fact,' said Wood with a smile; he had just returned with the book in his hand. And even as he spoke there was a stir in the clockwork of the great dark clock behind him and successive strokes thrilled through the room up to the number of seven. With the last stroke there came a crash from the floor above that shook the house like a thunderbolt; and Father Brown was already two steps up the winding staircase before the sound had ceased.
'My God!' cried Payne involuntarily; 'he is alone up there.'
'Yes,' said Father Brown without turning, as he vanished up the stairway. 'We shall find him alone.'
When the rest recovered from their first paralysis and ran helter– skelter up the stone steps and found their way to the new studio, it was true in that sense that they found him alone. They found him lying in a wreck of his tall camera, with its long splintered legs standing out grotesquely at three different angles; and Darnaway had fallen on top of it with one black crooked leg lying at a fourth angle along the floor. For the moment the dark heap looked as if he were entangled with some huge and horrible spider. Little more than a glance and a touch were needed to tell them that he was dead. Only the portrait stood untouched upon the easel, and one could fancy the smiling eyes shone.
An hour afterwards Father Brown in helping to calm the confusion of the stricken household, came upon the old steward muttering almost as mechanically as the clock had ticked and struck the terrible hour. Almost without hearing them, he knew what the muttered words must be.
In the seventh heir I shall return In the seventh hour I shall depart.
As he was about to say something soothing, the old man seemed suddenly to start awake and stiffen into anger; his mutterings changed to a fierce cry.
'You!' he cried; 'you and your daylight! Even you won't say now there is no Doom for the Darnaways.'
'My opinion about that is unchanged,' said Father Brown mildly. Then after a pause he added: 'I hope you will observe poor Darnaway's last wish, and see the photograph is sent off.'
'The photograph!' cried the doctor sharply. 'What's the good of that? As a matter of fact, it's rather curious; but there isn't any photograph. It seems he never took it after all, after pottering about all day.'
Father Brown swung round sharply. 'Then take it yourselves,' he said. 'Poor Darnaway was perfectly right. It's most important that the photograph should be taken.'
As all the visitors, the doctor, the priest, and the two artists trailed away in a black and dismal procession across the brown and yellow sands, they were at first more or less silent, rather as if they had been stunned. And certainly there had been something like a crack of thunder in a clear sky about the fulfilment of that forgotten superstition at the very time when they had most forgotten it; when the doctor and the priest had both filled their minds with rationalism as the photographer had filled his rooms with daylight. They might be as rationalistic as they liked; but in broad daylight the seventh heir had returned, and in broad daylight at the seventh hour he had perished.
'I'm afraid everybody will always believe in the Darnaway superstition now,' said Martin Wood.
'I know one who won't,' said the doctor sharply. 'Why should I indulge in superstition because somebody else indulges in suicide?'
'You think poor Mr Darnaway committed suicide?' asked the priest.
'I'm sure he committed suicide,' replied the doctor.
'It is possible,' agreed the other.
'He was quite alone up there, and he had a whole drug– store of poisons in the dark room. Besides, it's just the sort of thing that Darnaways do.'
'You don't think there's anything in the fulfilment of the family curse?'
'Yes,' said the doctor; 'I believe in one family curse, and that is the family constitution. I told you it was heredity, and they are all half mad. If you stagnate and breed in and brood in your own swamp like that, you're
