"So I came over here with Leigh on Sunday night," Nina Potter took up the story. "Miss Susan had loaned me your red coat, Kitty, last Wednesday to wear home when it blew up so cold. The coat is distinctive in appearance, and--well--" she faltered--"I knew if any one saw me, there was a chance I might be mistaken for you. Afterwards I got rid of the coat by selling it to a second-hand dealer." She caught her husband's averted gaze and colored painfully. "Leigh left me at the side door of 'Rose Hill,'" she added. "I entered the library--saw Miss Susan sitting there--dead--" she covered her eyes with her hand as if to shut out some terrifying vision and a shudder shook her. "I must have fainted, for it was late when I stole out of the house. I left by the front door, and in my terror I put the big key in the lock on the outside with some idea of locking poor Miss Susan in the house. I heard an automobile coming and ran away, forgetting to turn the key in the lock after all. When I got home I found Ben had not gotten in and that you were still asleep, Kitty--so--" she faltered again and glanced appealingly at her husband. Potter stirred uneasily. "I drove around a bit," he said. "Kitty, as I thought, coming over here at that time of night with Wallace troubled me, and I wanted time to think things over. When I heard of Cousin Susan's murder--well, I--well, I kept silent until my jealousy of Wallace drove me to try and implicate Kitty and him in the crime. "I saw you, Ted," he turned to Rodgers, "come out of a second-hand clothing store on Pennsylvania Avenue with Kitty's coat on your arm. The dealer told me that you had just paid twenty dollars for it. I decided that if the coat was worth that to you, it might be worth double the money to me: so I bribed the dealer to buy the coat back from you. When that scheme failed, I went to your apartment--" "Where you failed again," broke in Rodgers. "Your coat was accidentally burned up, Kitty, all except one pocket. In that pocket I found the clue which gave the first inkling that Charles Craige might have murdered your aunt--" "What was it?" demanded Kitty breathlessly. "An 'I.O.U.,' which your aunt must have slipped inside the coat pocket and forgotten. The signature was obliterated, but I recognized Craige's handwriting," Rodgers explained. "It showed me that Craige was under heavy financial obligations to Miss Susan Baird while all the time he protested absolute ignorance of her wealth. I immediately started to investigate Craige's career, and it was that investigation, as he said a few minutes ago, which forced his hand last night--" "And he nearly killed you!" Kitty's eyes were shining as she faced her lover. "You endangered your life for me--" Regardless of the others' presence Rodgers drew her to his side. "Sweetheart," he murmured. "Sweetheart--" "Ahem!" Ben Potter cleared his throat, and faced the others. "Did you get your letters, Nina?" he asked, turning to his wife.
