Midnight
Arms entwined about each other 's waists , the two girls read Henry Allen 's letter to his daughter 's friend . `` DEAR MISS DOROTHY , '' it began . `` Jane has written me that Firefly complains a great deal about being lonely . He misses Midnight , an old chum of his . So I decided that Midnight might come East , provided he had someone to look after his welfare . Jane has told me so much about you , and that you resemble one who , though gone from us , grows ever dearer with years . `` Because of this , and because of your many kindnesses to my girl , I hope you will accept Midnight for your own special pet .
