One of the central questions for starting a Dracula Dossier campaign is to decide how the agents are going to get the actual dossier. There are a couple of options given in the book, as well as some published operations that can do it. Two of those published operations are (S)Entries and the Harker Intrusion. I could not decide which, so I used both, roughly like this. (S)Entries is available in the Nights Black Agents core book, and The Harker Intrusion is one of the Edom Files adventures.
