The other looked at him inquisitively, and he laughed. “No,” he said, as if answering a question, “you needn’t be afraid of my competing; I’m leaving this place to-morrow.”

This cleared the air, and the dealer, whose name was Homberger, admitted that he was interested in books, and thought there might be in these old country-house libraries something to repay a journey. “For,” said he, “we English have always this marvellous talent for accumulating rarities in the most unexpected places, ain’t it?”

And in the course of the evening he was most interesting on the subject of finds made by himself and others. “I shall take the occasion after this sale to look round the district a bit; perhaps you could inform me of some likely spots, Mr Davidson?”

But Mr Davidson, though he had seen some very tempting locked-up book-cases at Brockstone Court, kept his counsel. He did not really like Mr Homberger.

Next day, as he sat in the train, a little ray of light came to illuminate one of yesterday’s puzzles. He happened to take out an almanac-diary that he had bought for the new year, and it occurred to him to look at the remarkable events for April 25. There it was: “St Mark. Oliver Cromwell born, 1599.”

That, coupled with the painted ceiling, seemed to explain a good deal. The figure of old Lady Sadleir became more substantial to his imagination, as of one in whom love for Church and King had gradually given place to intense hate of the power that had silenced the one and slaughtered the other. What curious evil service was that which she and a few like her had been wont to celebrate year by year in that remote valley? And how in the world had she managed to elude authority? And again, did not this persistent opening of the books agree oddly with the other traits of her portrait known to him? It would be interesting for anyone who chanced to be near Brockstone on the twenty-fifth of April to look in at the Chapel and see if anything exceptional happened. When he came to think of it, there seemed to be no reason why he should not be that person himself; he, and if possible, some congenial friend. He resolved that so it should be.

Knowing that he knew really nothing about the printing of Prayer-Books, he realized that he must make it his business to get the best light on the matter without divulging his reasons. I may say at once that his search was entirely fruitless. One writer of the early part of the nineteenth century, a writer of rather windy and rhapsodical chat about books, professed to have heard of a special anti-Cromwellian issue of the Prayer-Book in the very midst of the Commonwealth period. But he did not claim to have seen a copy, and no one had believed him. Looking into this matter, Mr Davidson found that the statement was based on letters from a correspondent who had lived near Longbridge; so he was inclined to think that the Brockstone Prayer-Books were at the bottom of it, and had excited a momentary interest.

Months went on, and St Mark’s Day came near. Nothing interfered with Mr Davidson’s plans of visiting Brockstone, or with those of the friend whom he had persuaded to go with him, and to whom alone he had confided the puzzle. The same 9.45 train which had taken him in January took them now to Kingsbourne; the same field-path led them to Brockstone. But to-day they stopped more than once to pick a cowslip; the distant woods and ploughed uplands were of another colour, and in the copse there was, as Mrs Porter said, “a regular charm of birds; why you couldn’t hardly collect your mind sometimes with it.”

She recognized Mr Davidson at once, and was very ready to do the honours of the Chapel. The new visitor, Mr Witham, was as much struck by the completeness of it as Mr Davidson had been. “There can’t be such another in England,” he said.

“Books open again, Mrs Porter?” said Davidson, as they walked up to the chancel.
