By the end of a week , she seemed quite herself . One morning every child in Primrose Court received a letter in the mail . It was written on gay-tinted paper with a pretty picture at the top . It read : `` You are cordially invited to a Halloween party to be given by Miss Laura Lathrop at 29 Primrose Court on Saturday evening , October 31 , at a half after seven . '' ---------------------- But as Maida ceased gradually to worry about Laura , she began to be troubled about Rosie . For Rosie was not the same child . Much of the time she was silent , moody and listless .
