`` Mr. Whitney sent me to call Mr. Ralph Mainwaring ; but I met Wilson again , and he said he had just told Mr. Mainwaring and Mr. Thornton , and was on his way to the room of young Mr. Mainwaring . Down the hall I met the butler and told him what had happened , and we both went into the library , and I stayed there till Mr. Whitney came . '' `` When did you last see Mr. Hugh Mainwaring ? '' `` Shortly after dinner last evening , between seven and eight o'clock , I should say , sir . '' `` Where was that ? '' `` In the main hall down-stairs , sir . He stopped me to say that he would not need me last evening , and that after locking up his rooms for the night I could have my time to myself . ''
