`` I do indeed , Dalton . Mr. Stonewell , Mr. Blunt is my son . He stands accused of having attempted , while in your company , and while in this disguise , to steal an examination . My son admits that the disguise is his property , and has been for months ; but he most solemnly assures me he was not with you last night , that he was not out of this building after seven o'clock . For this offense , of which you say he is guiltless , he stands recommended to be dismissed . Now I call upon you to state who was the man that was with you . '' `` Your son was not with me ; I shall make no further statement than that . ''
