'What on earth are you talking about?' cried Father Brown, and rapped the stones slightly with his stumpy umbrella, for he was a little less patient than usual.
'Oh, you'll find out all about it if you ask that picnic party of yours at the inn,' replied Boon scornfully. 'That man Tarrant seems to suspect me merely because I found the clothes; though he only came up a minute too late to find them himself. But there are all sorts of mysteries in this business. The little man with the big moustaches may have more in him than meets the eye. For that matter I don't see why you shouldn't have killed the poor fellow yourself.'
Father Brown did not seem in the least annoyed at the suggestion, but he seemed exceedingly bothered and bewildered by the remark. 'Do you mean,' he asked with simplicity, 'that it was I who tried to kill Professor Smaill?'
'Not at all,' said the other, waving his hand with the air of one making a handsome concession. 'Plenty of dead people for you to choose among. Not limited to Professor Smaill. Why, didn't you know somebody else had turned up, a good deal deader than Professor Smaill? And I don't see why you shouldn't have done him in, in a quiet way. Religious differences, you know… lamentable disunion of Christendom. … I suppose you've always wanted to get the English parishes back.'
'I'm going back to the inn,' said the priest quietly; 'you say the people there know what you mean, and perhaps they may be able to say it.'
In truth, just afterwards his private perplexities suffered a momentary dispersal at the news of a new calamity. The moment he entered the little parlour where the rest of the company were collected, something in their pale faces told him they were shaken by something yet more recent than the accident at the tomb. Even as he entered, Leonard Smyth was saying:' Where is all this going to end?'
'It will never end, I tell you,' repeated Lady Diana, gazing into vacancy with glassy eyes; 'it will never end till we all end. One after another the curse will take us; perhaps slowly, as the poor vicar said; but it will take us all as it has taken him.'
'What in the world has happened now?' asked Father Brown.
There was a silence, and then Tarrant said in a voice that sounded a little hollow: 'Mr Walters, the Vicar, has committed suicide. I suppose it was the shock unhinged him. But I fear there can be no doubt about it. We've just found his black hat and clothes on a rock jutting out from the shore. He seems to have jumped into the sea. I thought he looked as if it had knocked him half–witted, and perhaps we ought to have looked after him; but there was so much to look after.'
'You could have done nothing,' said the lady. 'Don't you see the thing is dealing doom in a sort of dreadful order? The Professor touched the cross, and he went first; the Vicar had opened the tomb, and he went second; we only entered the chapel, and we–'
'Hold on,' said Father Brown, in a sharp voice he very seldom used; 'this has got to stop.'
He still wore a heavy though unconscious frown, but in his eyes was no longer the cloud of mystification, but a light of almost terrible understanding. 'What a fool I am!' he muttered. 'I ought to have seen it long ago. The tale of the curse ought to have told me.'
'Do you mean to say,' demanded Tarrant, 'that we can really be killed now by something that happened in the thirteenth century?'
Father Brown shook his head and answered with quiet emphasis: 'I won't discuss whether we can be killed by something that happened in the thirteenth century; but I'm jolly certain that we can't be killed by something that never happened in the thirteenth century, something that never happened at all.'
'Well,' said Tarrant, 'it's refreshing to find a priest so sceptical of the supernatural as all that.'
'Not at all,' replied the priest calmly; 'it's not the supernatural part I doubt. It's the natural part. I'm exactly in the position of the man who said, 'I can believe the impossible, but not the improbable.
'That's what you call a paradox, isn't it?' asked the other.
'It's what I call common sense, properly understood,' replied Father Brown. 'It really is more natural to believe a preternatural story, that deals with things we don't understand, than a natural story that contradicts things we do understand. Tell me that the great Mr Gladstone, in his last hours, was haunted by the ghost of Parnell, and I will be agnostic about it. But tell me that Mr Gladstone, when first presented to Queen Victoria , wore his hat in her drawing–room and slapped her on the back and offered her a cigar, and I am not agnostic at all. That is not impossible; it's only incredible. But I'm much more certain it didn't happen than that Parnell's ghost didn't appear; because it violates the laws of the world I do understand. So it is with that tale of the curse. It isn't the legend that I disbelieve–it's the history.'
Lady Diana had recovered a little from her trance of Cassandra, and her perennial curiosity about new things began to peer once more out of her bright and prominent eyes.
'What a curious man you are!' she said. 'Why should you disbelieve the history?'
'I disbelieve the history because it isn't history,' answered Father Brown. 'To anybody who happens to know a little about the Middle Ages, the whole story was about as probable as Gladstone offering Queen Victoria a cigar. But does anybody know anything about the Middle Ages? Do you know what a Guild was? Have you ever heard of salvo managio suo? Do you know what sort of people were Servi Regis?
'No, of course I don't,' said the lady, rather crossly. 'What a lot of Latin words!'
'No, of course,' said Father Brown. 'If it had been Tutankhamen and a set of dried–up Africans preserved, Heaven knows why, at the other end of the world; if it had been Babylonia or China; if it had been some race as remote and mysterious as the Man in the Moon, your newspapers would have told you all about it, down to the last discovery of a tooth–brush or a collar–stud. But the men who built your own parish churches, and gave the names to your own towns and trades, and the very roads you walk on – it has never occurred to you to know anything about them. I don't claim to know a lot myself; but I know enough to see that story is stuff and nonsense from beginning to end. It was illegal for a money–lender to distrain on a man's shop and tools. It's exceedingly unlikely that the Guild would not have saved a man from such utter ruin, especially if he were ruined by a Jew. Those people had vices and tragedies of their own; they sometimes tortured and burned people. But that idea of a man, without God or hope in the world, crawling away to die because nobody cared whether he lived – that isn't a medieval idea. That's a product of our economic science and progress. The Jew wouldn't have been a vassal of the feudal lord. The Jews normally had a special position as servants of the King. Above all, the Jew couldn't possibly have been burned for his religion.'
'The paradoxes are multiplying,' observed Tarrant; 'but surely, you won't deny that Jews were persecuted in the Middle Ages?'
'It would be nearer the truth,' said Father Brown, 'to say they were the only people who weren't persecuted in the Middle Ages. If you want to satirize medievalism, you could make a good case by saying that some poor Christian might be burned alive for 'making a mistake about the Homoousion, while a rich Jew might walk down the street openly sneering at Christ and the Mother of God. Well, that's what the story is like. It was never a story of the Middle Ages; it was never even a legend about the Middle Ages. It was made up by somebody whose notions came from novels and newspapers, and probably made up on the spur of the moment.'
The others seemed a little dazed by the historical digression, and seemed to wonder vaguely why the priest emphasized it and made it so important a part of the puzzle. But Tarrant, whose trade it was to pick the practical detail out of many tangles of digression, had suddenly become alert. His bearded chin was thrust forward farther than ever, out his sullen eyes were wide awake. 'Ah,' he said; 'made up on the spur of the moment!'
'Perhaps that is an exaggeration,' admitted Father Brown calmly. 'I should rather say made up more casually and carelessly than the rest of an uncommonly careful plot. But the plotter did not think the details of medieval history would matter much to anybody. And his calculation in a general way was pretty nearly right, like most of his other calculations.'
'Whose calculations? Who was right?' demanded the lady with a sudden passion of impatience. 'Who is this person you are talking about? Haven't we gone through enough, without your making our flesh creep with your he's and him's?'
'I am talking about the murderer,' said Father Brown.
'What murderer?' she asked sharply. 'Do you mean that the poor Professor was murdered?'
'Well,' said the staring Tarrant gruffly into his beard, 'we can't say 'murdered', for we don't know he's killed.'
'The murderer killed somebody else, who was not Professor Smaill,' said the priest gravely.
