t when a name is mentioned in connection with
such stories, there is usually some truth at the bottom of
them. And a name is mentioned in this case, though I do not
think it worth my while to repeat it here; and loth as I am to
recognize the fact, it is a name that carries with it doubts

packed his master's portmanteau at eight o'clock and at ten
called a carriage and rode with the Doctor to the Twenty-ninth
Street station. He was told to buy tickets for Poughkeepsie
where his master had been called in consultation, and having
done this, hurried back to join his master on the platform.
They had walked together as far as the cars, and Dr. Zabriskie
was just stepping on to the train when a man pushed himself
hurriedly between them and whispered something into his
master's ear, which caused him to fall back and lose his
