The Man in Lower Ten by Mary Roberts Rinehart

That was Saturday night, two weeks after the wreck. The previous five days had been full of swift-following events -- the woman in the house next door, the picture in the theater of a man about to leap from the doomed train, the dinner at the Dallases', and Richey's discovery that Alison was the girl in the case. In quick succession had come our visit to the Carter place, the finding of the rest of the telegram, my seeing Alison there, and the strange interview with Mrs. Conway. The Cresson trip stood out in my memory for its seriocomic horrors and its one real thrill. Then -- the discovery by the police of the sealskin bag and the bit of chain; Hotchkiss producing triumphantly Stuart for Sullivan and his subsequent discomfiture; McKnight at the station with Alison, and later the confession that he was out of the running.

And yet, when I thought it all over, the entire week and its events were two sides of a triangle that was narrowing rapidly to an apex, a point. And the said apex was at that moment in the drive below my window, resting his long legs by sitting on a carriage block, and smoking a pipe that made the night hideous. The sense of the ridiculous is very close to the sense of tragedy. I opened my screen and whistled, and Johnson looked up and grinned. We said nothing. I held up a handful of cigars, he extended his hat, and when I finally went to sleep, it was to a soothing breeze that wafted in salt air and a faint aroma of good tobacco. I was thoroughly tired, but I slept restlessly, dreaming of two detectives with Pittsburg warrants being held up by Hotchkiss at the point of a splint, while Alison fastened their hands with a chain that was broken and much too short. I was roused about dawn by a light rap at the door, and, opening it, I found Forbes, in a pair of trousers and a pajama coat. He was as pleasant as most fleshy people are when they have to get up at night, and he said the telephone had been ringing for an hour, and he didn't know why somebody else in the blankety-blank house couldn't have heard it. He wouldn't get to sleep until noon.
