DuPont Diary

The diary of Henry DuPont


Approximately ninety pages in length, it is not what one would call a conventional diary; rather it discusses the DuPont family lineage and history. There are, however, specific entries pertaining to various dates and events.


The diary is given to Ivy Morgan, Jonas Markham, and Ray Brannigan by Henry DuPont when they arrive at his family estate in Steeplin County.

June 20, 1926

Booth and I have arrived in Arkham under the cover of darkness. I procured a local residence when I learned about the auction, and with luck will find a number of trust-worthy souls to acquire the statue.

If my information is accurate, $3,000 should be enough to ensure that my agents will have the winning bid.

What happens after that is a matter for fate to decide.
