“Now, let’s see where we are,” he said, as they went round to Portman Square. “We do know for a certainty that Jacob Herapath had a transaction of some sort with one Luigi Dimambro, on November 12th, and that it resulted in his handing, or sending, the said Luigi a cheque for three thousand guineas. Let’s see if we can’t find some trace of it, or some mention of it, or of previous dealings with Dimambro, amongst Jacob’s papers. I suppose we can get access to everything here at the house, and down at the office, too, can’t we? The probability is that the transaction with Dimambro was not the first. There must be something, Selwood—memoranda, letters, receipts—must be!”
But Selwood shook his head and uttered a dismal groan.
“Another of my late employer’s peculiarities,” he answered, “was that he never gave or took receipts in what one may call word-of-mouth transactions! He had a rooted—almost savage—objection to anybody asking him for a receipt for cash; he absolutely refused to take one if he paid cash. I’ve seen him pay several thousand pounds for a purchase and fling the proffered receipt in the fire in the purchaser’s presence. He used to ask—vehemently!—if you wanted receipts for a loaf of bread or a pound of beef-steak. I’m afraid we shan’t find much of that sort. As to letters and memoranda, Mr. Herapath had a curious habit which gave me considerable trouble of mind when I first went to him, though I admit it was a simple one. He destroyed every letter he ever got as soon as he’d answered it. And as he insisted on everything being answered there and then, there’s no great accumulation of paper in that way!”
“We’ll see what there is, anyhow,” said the Professor. “If we could find something, anything—a mere business card, a letter-heading—that would give us Dimambro’s permanent address, it would be of use. For I’m more and more convinced that Dimambro was the man who called at the House of Commons that night, and if it was Burchill who dined with him that same evening, why, then—but come along, let’s have a look at Jacob’s desk in the house here, and after that we’ll go down to the estate offices and see if we can find anything there.”
This was a Saturday morning—during the whole of that afternoon and evening the Professor and Selwood examined every drawer and receptacle in which Jacob Herapath’s papers lay, both at Portman Square and at Kensington. And, exactly as Selwood had said, there was next to nothing of a private nature. Papers relating to Parliamentary matters, to building schemes, to business affairs, there were in plenty, duly filed, docketed, and arranged, but there was nothing of the sort that Cox-Raythwaite hoped to find, and when they parted, late at night, they were no wiser than when they began their investigations.
“Go home to bed,” counselled the Professor. “Put the whole thing out of your head until Monday morning. Don’t even think about it. Come and see me on Monday, first thing, and we’ll start again. For by the Lord Harry! I’ll find out yet what the real nature of Jacob Herapath’s transaction with Dimambro was, if I have to track Dimambro all through Italy!”
Selwood was glad enough to put everything out of his mind; it seemed to him a hopeless task to search for a man to whose identity they only had the very faintest clue. But before noon of the next day—Sunday—he was face to face with a new phase of the problem. Since her uncle’s death, Peggie had begun to show a quiet reliance on Selwood. It had come to be tacitly understood between them that he was to be in constant attendance on her for the present, at any rate. He spent all his time at the house in Portman Square; he saved its young mistress all the trouble he could; he accompanied her in her goings and comings. And of late he had taken to attending her to a certain neighbouring church, whereto Peggie, like a well-regulated young lady, was constant in her Sunday visits. There in the Herapath family pew, he and Peggie sat together on this particular Sunday morning, neither with any thought that the Herapath mystery had penetrated to their sacred surroundings. Selwood had been glad to take Cox-Raythwaite’s advice and to put the thing out of his mind for thirty-six hours: Peggie had nothing in her mind but what was proper to the occasion.
Jacob Herapath had been an old-fashioned man in many respects; one of his fads was an insistence upon having a family pew in the church which he attended, and in furnishing it with his own cushions, mats, and books. Consequently Peggie left her own prayer-book in that pew from Sunday to Sunday. She picked it up now, and opened it at the usual familiar place. And from that place immediately dropped a folded note.
Had this communication been a billet-doux, Peggie could hardly have betrayed more alarm and confusion. For a moment she let the thing rest in the palm of her hand, holding the hand out towards Selwood at her side; then with trembling fingers she unfolded it in such a fashion that she and Selwood read it together. With astonished eyes and beating hearts they found themselves looking at a half-sheet of thin, foreign-looking notepaper, on which were two or three lines of typewriting:
“If you wish to save your cousin Barthorpe’s life, leave the church and speak to the lady whom you will find in a private automobile at the entrance to the churchyard.”
