"Did no one else go to his rooms from two in the afternoon to the arrival of Lydia next morning?"

"Who passed your lodge and went to Masters's staircase on the day before Chairo and Lydia went there?"

"There may have been others; I don't see every one who passes the lodge."
"Did any one that night gain admission after dark?"
