Welling: "Why, it's very simple—that is, it's the most difficult thing in the world. Nelly, can you believe anything I say to you?"
Miss Greenway: "What nonsense! Of course I can—if you're not too long about it."
Welling: "Well, then, the letter in that envelope was one I wrote to Mrs. Campbell—or the copy of one."
Miss Greenway: "The copy?"
Welling: "But let me explain. You see, when I got your note asking me to be sure and come to Mrs. Curwen's—"
Miss Greenway: "Yes?"
Welling: "—I had just received an invitation from Mrs. Campbell for her garden-party, and I sat down and wrote to you, and concluded I'd step over and tell her why I couldn't come, and with that in mind I addressed your letter—the one I'd written you—to her."
Miss Greenway: "With my name inside?"
Welling: "No; I merely called you 'darling'; and when Mrs. Campbell opened it she saw it couldn't be for her, and she took it into her head it must be for Miss Rice."
Miss Greenway: "For Margaret? What an idea! But why did she put your envelope on it?"
