Henry William Herbert Wikipedia page.
"He was staying at the Stevens Hotel in Manhattan, New York City and invited several men to dine with him on what would be the last night of his life. Only one gentleman accepted his invention, Philip Hone Anthon, a pupil of Herbert's, who most likely accepted the invitation due to Herbert's plea that he was very lonely, after which he begged Anthon to spend as much time as possible with him. Herbert took his own life on 17 May 1858 at 2:00 am."
Yeah, well, Edgar, takes one to know one.
I checked a mystery novel out of the library the other day which features E.A. Poe detecting along with his character Auguste Dupin. Haven't started it yet.
