Convalescence - A 1920s Adventure for Call of Cthulhu - Miskatonic Repository

Wounded investigators take time to heal in a quiet country clinic near Dublin. Almost mended, they are ready to be voluntarily discharged. But they wake to two horrifying and gruesome murders that makes them fear that among angels of mercy may walk an angel of death.

In this single map one-shot adventure, playable in a single session by two or more players, investigators begin under the threat of peril and must use their wits and skills to separate lie from truth, discover the wounds that time won’t heal, and stop who or what killed a patient and her companion.

This adventure includes 13 pages of scenario information, seven pages of handouts, and six pre-generated investigators to use at the Keeper's discretion.

Adventure Features:

  • The scenario overview contains the essential details: a thorough map and key with locations, encounters, and SAN penalties.
  • To aid the Keeper, all clues appear in an at-a-glance section for easy reference.
  • Possible story hooks, opportunities for investigators to acquire weapons, and several potential outcomes make it easy for a Keeper to run.
  • The mix of NPCs and the Cthulhu Mythos connection enable varied possibilities for scenario resolution.
  • Color handouts.

Trigger warnings: Horror, Religion, Violence

The adventure begins on an early sunny Sunday morning in August 1922 near Dublin, Ireland. The staff of St. Midabaria Clinic wake to discover two murders. Sister Clarissa, an old nun and former nursing instructor, checked herself into the clinic the night before. Her body lays in a pool of her own blood after a brutal attack in her private room. Father O’Donnelly, her colleague and traveling companion, was viciously strangled in the clinic’s chapel. Who or what killed them? It's up to the investigators to find out, especially before they're next.

Investigators may be recently recovered patients at the clinic, or possibly contacts who have arrived to provide transportation, or even seekers of cultist connections. This scenario is suitable for new or experienced players. It can be run standalone or as an interlude in a larger campaign. Investigators are always getting injured and finding a reason to get them into a clinic isn't difficult. Getting them out ... that's another story.

The scenario encompasses five chapters with approximate timings:

  • Chapter 1: Killings at the Clinic — The investigators hear about the two murders at the clinic overnight and the administrator begs for their help. (10 minutes)
  • Chapter 2: Searching for Secrets — The investigators explore the clinic, interview the staff, and discover clues. (90 minutes)
  • Chapter 3: Authorities Arrive — The investigators face the police, who are an obstacle and increase the danger. (20 minutes)
  • Chapter 4: [redacted to prevent spoilers] (30 minutes)
  • Chapter 5: [redacted to prevent spoilers] (10 minutes)

The downloads for this adventure consist of:

  • A PDF in typical Call of Cthulhu style
  • A simplified PDF for easy readability and scrolling, with text for any handouts where applicable
  • A ZIP file containing all handouts and NPC portraits as individual images 
  • A ZIP file containing six pre-generated investigator sheets


This is a SanityFree Adventure, with thanks to Storytelling Collective and Chaosium. Additional gratitude to Jon Hook, who wrote Transatlantic Terror for Goodman Games, the end of which saw my own players ejected from the R.M.S. Adriatic in Ireland, which then led to the start of this scenario idea.

Some players were harmed in the making of this adventure, or so they tell me. They got better.

If you are considering playing this scenario in an online virtual tabletop, you may want to look at the new map I've designed and published called St Midabaria Clinic -- A Clinic Map for 1920s Call of Cthulhu 7th Edition -- Miskatonic Repository. That special map is not required, but you may like it!

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
