He and Louise had no conversation together until that night. Gertrude and Alex—I mean Jack—had gone for a walk, although it was nine o’clock, and anybody but a pair of young geese would have known that dew was falling, and that it is next to impossible to get rid of a summer cold. At half after nine, growing weary of my own company, I went downstairs to find the young people. At the door of the living-room I paused. Gertrude and Jack had returned and were there, sitting together on a divan, with only one lamp lighted. They did not see or hear me, and I beat a hasty retreat to the library. But here again I was driven back. Louise was sitting in a deep chair, looking the happiest I had ever seen her, with Halsey on the arm of the chair, holding her close. It was no place for an elderly spinster. I retired to my upstairs sitting-room and got out Eliza Klinefelter’s lavender slippers. Ah, well, the foster motherhood would soon have to be put away in camphor again. The next day, by degrees, I got the whole story. Paul Armstrong had a besetting evil—the love of money. Common enough, but he loved money, not for what it would buy, but for its own sake. An examination of the books showed no irregularities in the past year since John had been cashier, but before that, in the time of Anderson, the old cashier, who had died, much strange juggling had been done with the records. The railroad in New Mexico had apparently drained the banker’s private fortune, and he determined to retrieve it by one stroke. This was nothing less than the looting of the bank’s securities, turning them into money, and making his escape. But the law has long arms. Paul Armstrong evidently studied the situation carefully. Just as the only good Indian is a dead Indian, so the only safe defaulter is a dead defaulter. He decided to die, to all appearances, and when the hue and cry subsided, he would be able to enjoy his money almost anywhere he wished. The first necessity was an accomplice. The connivance of Doctor Walker was suggested by his love for Louise. The man was unscrupulous, and with the girl as a bait, Paul Armstrong soon had him fast. The plan was apparently the acme of simplicity: a small town in the west, an attack of heart disease, a body from a medical college dissecting-room shipped in a trunk to Doctor Walker by a colleague in San Francisco, and palmed off for the supposed dead banker. What was simpler? The woman, Nina Carrington, was the cog that slipped. What she only suspected, what she really knew, we never learned. She was a chambermaid in the hotel at C—, and it was evidently her intention to blackmail Doctor Walker. His position at that time was uncomfortable: to pay the woman to keep quiet would be confession. He denied the whole thing, and she went to Halsey.
