The Millionaire Baby by Anna Katharine Green

So far in this narrative I have kept from the reader nothing but an old experience of which I was now to make use. This experience involved Mrs. Ocumpaugh, and was the cause of the confidence which I had felt from the first in my ability to carry this search through to a successful termination. I believed that in some secret but as yet undiscovered way, it offered a key to this tragedy. And I still believed this, little as I had hitherto accomplished and blind as the way continued to look before me.

Nevertheless, it was with anything but a cheerful heart that I advanced that morning through the shrubbery toward the Ocumpaugh mansion.
