Underground, Overground: The Case File Collection is an anthology of scenarios—and more, for the roleplaying game based on the Rivers of London novels by Ben Aaronovitch. In this roleplaying game, as magic returns to the world, there is the need to deal with the mysteries, oddness, and secrets of the ‘demi-monde’, as well as investigate crimes committed by those within it and those associated with it. In this urban fantasy game, this need is fulfilled by the London Metropolitan Police Service’s special magic branch, also known as ‘the Folly’, and the Player Characters are its newly recruited members. Magic plays a big role in Rivers of London: the Roleplaying Game and some of the Player Characters are practitioners—Apprentice Newtonian Wizards—who will need their magic to best solve the mysteries that lie at the heart of the mysteries of these four scenarios as well as general investigative abilities, some taught at Police College and some learned on the street. Together, the quartet will do things. First, they will take the Player Characters across London as well as below the city and along the banks of the River Thames, second, they will take the Player Characters through a series of increasingly challenging and more involved cases. In terms of timeframe, the scenarios in the anthology are still set in 2016, but the content does take into account of the events of the novella, What Abigail Did That Summer.
It should be noted that four of the the three scenarios in Underground, Overground: The Case File Collection are not new, having previously been available as PDFs, whilst the first two scenarios are suitable as introductory scenarios as well as convention scenarios. The first of the four scenarios is ‘Going Underground’, a short mystery which takes place in an ‘ghost’ or unused station on the London underground, this being the British Museum station closed in the thirties. The British Museum station is now a ‘ghost station’—and it is this conflation of ‘ghost’ and ‘station’ which the author takes advantage of and should arouse the interest of the players and their characters. The Player Characters are awoken by a telephone call in the night from Sergeant Jaget Kumar, the Falcon Liaison Officer for the British Transport Police, who reports that ghost has been sighted on the station. The Player Characters are able to conduct a little research before making their way to the station entrance (it is quite close to the Folly) before descending to the remanets of the station where most of the action will take place. This is a constrained investigation, focusing upon making contact with the ghost there and finding out about what happened to them. However, this hides a deeper mystery connected to the British Museum next door, which is reputed to have been haunted by its very own ‘Unlucky Mummy’.
If there is an issue with ‘Going Underground’, it is that there is not a lot of action to the scenario, so some players may be disappointed. However, it is written as an investigative and social scenario and it has a gentle, almost cosy feel to it. This is a genuinely lovely scenario very nicely supported with some well-researched background.
‘The Goat-Man is Coming!’ is the third scenario in the anthology and is the only not have been published before. When the Folly is alerted by the local police liaison officer about an assault by a supposed ‘Goat-Man’ on the Parkland Walk, a linear green pedestrian and cycle route in north London, Inspector Nightingale asks the Player Characters to investigate as the ‘Goat-Man’ is a figure of local myth and has not been seen since the seventies. Much of the action of the scenario is along the few kilometres of the Parkland Walk as the Player Characters investigate the assault and check the veracity of the ‘Goat-Man’ myth. This is very much a step up in terms of the investigation’s sophistication with numerous NPCs to interact with—some of whom are quite challenging to interview—and multiple leads. The players will definitely need to make notes to keep up with the amount of information their characters can discover and learn. The scenario also presents an opportunity for the Player Characters to interact with members of the demi-monde, including a Len Deighton-inspired fox whom the Game Master will have a lot of fun portraying.
As with the other scenarios in Underground, Overground, the issue with ‘Jimmy’s Last Dance’ is when it is set, but add to that is its political dimension. It is set in 2016 and it involves a political scandal that was at its height at the time. This is The Windrush Scandal. Of course, the authors advise the Game Master to handle the issue with care and it is certainly not a problem that The Windrush Scandal is part of the scenario—in fact, it is actually woven into the plot of the case file—but rather that the timeframe is quite specific and thus difficult to shift the case file to another year. Elsewhere, there is advice on how to portray a pirate without sounding like Robert Newton. Overall, a very nicely detailed investigation that combines parochially British charm and menace, but like a modern Ealing comedy, can have a cosy ending.
Physically, Underground, Overground: The Case File Collection is very nicely produced. It is well written, the illustrations are excellent, the cartography good, and the handouts decent.
Ultimately, the only issue with Underground, Overground: The Case File Collection is the time frame in which its scenarios are set, often quite tightly bound to 2016. This is not an insurmountable problem, and the individual scenarios do each give advice how to handle this if the Game Master wants to set them else when. This aside, all four scenarios are thoroughly entertaining, whatever their degree of detail and investigation, exploring different parts and aspects of London, as well introducing further elements of the demi-monde. Players will love it for the means to create and roleplaying talking Foxes, but that is just extra to the collection of intriguing investigations and mysteries in Underground, Overground: The Case File Collection that provide great support for the Rivers of London: the Roleplaying Game.
