midnight
It was probably Flagg 's dinner hour . Mrs. Morgan , the landlady in Macdougal Street , a melancholy little soul , was now the only link between me and my kinsman . I had a weekly interview with her . I learned that Mr. Flagg slept late , was seldom in during the day , and usually returned after midnight . A person with this eccentric scheme of life was not likely to be at home at such hours as I might find it convenient to call . Nevertheless , from time to time I knocked at the unresponsive door of his room . The two notes I had written to him he left unanswered .
