It contained a card and a written note , and on the card was an invitation , as follows : `` The Colonel and Officers of the West Bromwich Regiment request the pleasure of the company of Mr. Jones , the Misses Jones , and Mr. Francis Jones to a dance at the Galway Barracks , on the 20th of May , 1881 . Dancing to commence at ten o'clock . '' Then there was the note , which Edith read before she took the card upstairs . `` My dear Miss Jones , '' the letter began . Edith again looked at the envelope and perceived that the despatch had been certainly addressed to herself -- Miss Edith Jones ; but between herself and her sister there could be no jealousy as to the opening of a letter .
