London is a boxed set which consists of three books - guidebooks for the Keeper and for Investigators and a collection of adventures. There are also four poster-sized period maps and six sheets of hand-outs for use in games.

The Curse of Nineveh is a campaign with seven adventures. It and its two companion books formed part of the Kickstarter campaign.

The Journal of Neve Selibuc is a companion to The Curse of Nineveh and is used in conjunction with that book, providing the investigators with clues and information that can help them complete the scenarios.

The Journal of Reginald Campbell Thompson is a second companion book to The Curse of Nineveh and also is used to provide clues.

London Boxed Postcard Set is a collection of nineteen-twenties style postcards to be used as plot hooks in the game with a companion book expanding on the ideas provided. The cards are written by different role-playing game writers and was available exclusively to backers of the Kickstarter. It is due for release in 2016.
