10 P.M.
Given Aunt Elizabeth , he will complete the equation . If Mrs. Chataway should fail me -- But I wo n't suppose that Mrs. Chataway will fail . I must be sure and explain to Tom about Dr. Denbigh . `` The Sphinx , '' New York , 10 P.M. -- I arrived -- that is to say , we arrived in this town at ten minutes past one o'clock , almost ten hours ago . Dr. Denbigh has gone somewhere -- and that reminds me that I forgot to ask him where . I never thought of it until this minute , but it has just occurred to me that it may be quite as well from an ignorant point of view that `` The Sphinx '' excludes mere man from its portals . He was good to me on the train , very good indeed .
