One thought, that at first had been merely a vague wonder, grew greater and greater till it fairly pressed all else from David's mind: where had Philip got the five thousand dollars for which Lillian Drew had sold him three months' silence? David knew that Philip Morton had not a penny of private fortune, only his income as head of the Mission; and that of this income not a dollar had been laid by, so open had been his purse to the hand of distress. He could not have borrowed the money in the usual manner, for he had no security to give; and sums such as this are not blindly loaned with mere friendship as the pawn. David entered Philip's study with this new dread pulsing through him. It was his duty to his friend to know the truth, and besides, his suspense was too acute to permit remaining in passive ignorance; so he locked the study door and began seeking evidence to dispel or confirm his fear. He took the books from the safe--he remembered the combination from the summer he had spent at the Mission--and turned them through, afraid to look at each new page. But the books dealt only with small sums for incidental expenses; the large bills were paid by cheque from the treasurer of the Board of Trustees. There was nothing here. He looked through the papers in the desk--among them no reference to the money. He scrutinised every page of paper in the safe, except the contents of one locked compartment. No reference. Knowing he would find nothing, he examined Morton's private bank-book: a record of the monthly cheque deposited and numerous small withdrawals--that was all. And then he picked up a note-book that all the while had been lying on the desk. He began to thumb it through, not with hope of discovering a clue but merely as a routine act of a thorough search. It was half engagement book, half diary. David turned to the page dated with the day of Morton's death, intending to work from there backwards--and upon the page he found this note of an engagement: "5 P. M.--at Mr. Haddon's office--first fall meeting of Boy's Farm Committee." He turned slowly back through the leaves of September, August, July, June, finding not a single suggestive record. But this memorandum, on the fifteenth of May, stopped him short: "Boy's Farm Committee adjourned to-day till fall, as Mr. Chambers and Mr. Haddon go to Europe. Money left in Third National Bank in my name, to pay for farm when formalities of sale are completed." Instantly David thought of an entry on the first of June recording that, with everything settled save merely the binding formalities, the farmer had suddenly broken off the deal, having had a better offer.
