I acknowledge that the Forensic Entomology ability, as seen in The Esoterrorists, can be hard to love. It’s icky and creepy.

And that’s what’s good about it.

Also a favorite of forensics procedural shows, for exactly that reason, I included it as a separate item in The Esoterrorists precisely because it dovetails so well with the horror genre.

Yet it can be hard to come up with new uses for the skill in scenarios.

Once you’ve used the old saw of timing the cause of death of a corpse from the state of the maggots and flies infested the flesh, where do you go?

Sure, you can have a victim infested with a bug or parasite that only comes from certain areas. For example, a body found in a non-tropical environment could show the distinctive flesh-eating qualities of leishmaniasis. The protozoans responsible for this body horror get into people via sandfly bites. That core clue could lead you to discover that the victim recently returned from the cursed city of a monkey god. (You’re all itching to point out that leishmaniasis is not nearly as uncommon as the article implies, with 12 million victims around the world at any time. But hey, when you’re proving there’s a monkey god curse, you have to take what nature gives you to work with.)

But here’s another great ghoulish detail: the apparent blood spatter at your crime scene could turn out to be nothing more than fly spit.

Once your character uses the test described in that last link, she can exonerate the innocent family member accused of a gruesome slaying on the basis of that falsely identified blood spatter.

Having ruled that out, you can then move on to hunt down the Outer Dark Entity that really committed the crime. Maybe it specializes in framing victims, and impelled the flies to spit in a particularly incriminating manner.

Whether you go that far or not, this kind of test is all in a day’s work for our nation’s undersung heroes, the forensic entomologists.

A rules option for GUMSHOE horror games

In situations where a Sense Trouble test might reveal the presence of danger from an otherworldly or eerie source, offer the players a chance to pay a price later in exchange for a benefit now.

One player gets an automatic success at a Sense Trouble test by agreeing to take on a Stability penalty that lasts for the rest of the scenario. Let’s call this a Stability Handicap.

In the typical situation in which Sense Trouble merely allows the element of surprise in a fight already guaranteed to happen, that penalty is -1.

If the test lets them entirely avoid a significant hazard or skip a fight with something nasty they don’t want or need to tangle with, the penalty rises to -2.

In the story, the moment represents a sudden flash of eerie awareness, attuning the recipient to eldritch energies. Depending on the situation, you might narrate:

  • a jackhammering heart

  • the nearly overwhelming urge to vomit

  • a jolt of rootless anxiety

  • an epiphany of cosmic dread

  • the appearance of a rash, welts, or other psychic injuries

  • an overpowering smell unsensed by anyone else present

  • an awful vision of monstrous violence that surfaces in the mind for a split-second and is then immediately suppressed

Make this a rare option, keyed to specific story events. You may decide that it only makes sense for characters already exposed to the supernatural, or those who have succumbed in some way to its influence.

Offer it only when the rest of the scenario holds out the possibility of at least 2 Stability tests.

The more physical symptoms for the Sense Trouble success might instead call for an Athletics or Scuffling Handicap. Instead of increasing your mental vulnerability, that rash that came out of nowhere makes it harder to throw punches.

For an additional fraught choice, you could even let the player choose which of the three abilities to Handicap. In that case you can allow the Handicap even if you aren’t sure that 2 or more tests of each ability still remain in the scenario. Correctly predicting which Handicap will hurt the least becomes part of the player’s challenge. Here the cost lies in the anxiety of decision making as much as in any actual penalties dished out in later scenes. If players always guess right, and Handicaps start to feel like a free gift, make sure they pay the piper next time around. See to that a penalty happens, in a situation with truly harrowing stakes.

a Column About Roleplaying

Was it a whole ten years ago that Simon Rogers and I sat by ourselves at a small table on the far fringes of the Gen Con exhibit hall? It feels like only yesterday, that forlorn time when we had nothing to lure passersby but a stack of The Esoterrorists first edition and some Dying Earth books. Yes, it’s the tenth anniversary of GUMSHOE and although we were slow burners at first, the system has gradually inveigled its way into gaming’s collective consciousness. We could have no more humbling/ego inflating proof of that than Pelgrane’s amazing showing at this year’s ENnie Awards. I should count myself lucky that Simon, Cat, Ken and Gar left a few medals on the table for Feng Shui 2.

On such occasions, one’s thoughts naturally turn to think pieces, and Simon has asked me to look at ways in which GUMSHOE scenarios have changed since the early days.

To me the key innovation has to be the addition of Lead-In and Lead-Out lines to the scene headers. These immediately show the GM where the scene probably fits in the investigative sequence the players create as they wend their way through the mystery. For example:

Harp’s Place

Scene Type: Core

Lead-Ins: The Bait, What’s Up With Chuck

Lead-Outs: Irland is Missing, Dawley, The Water Commission

Although we sometimes also still do scene sequence diagrams, they only really work for very simple, more or less linear scenarios. The more possible ways through the investigation a scenario provides, the more tangled and confused the web of scene connections looks when expressed in diagram form. Instead of acting as a play aid, a diagram makes the scenario look more daunting than it really is. Lead-Ins and Lead-Outs put the information in front of GMs when they really need it—while they’re running the scenes.

From a scenario design standpoint, they encourage the writer to include multiple ways in and out of their scenes, giving players additional options and fighting linearity.

The other big change, Gar has pointed out, can be seen in the way Investigative point spends are treated. Some early scenarios went a bit off-model by requiring overly high spends for benefits. If you see a 3-point spend in an early adventure, you can almost always strike that out in exchange for a 2 or even a 1. Other early adventures sometimes get stingy by making only the core clues free, and charging for other information you don’t need. Since those first scenarios we have more consistently adopted the approach I have always used, which is to provide plenty of info for free and make the players separate the pertinent from the incidental.

Over the years we have also learned how emotionally invested players become when they choose to spend an investigative point. I initially conceived of investigative spends as just a grace note, a fun minor occurrence that would happen every now and again. No big deal. That thought underestimated the cognitive difficulty of letting go of a resource—any resource. Early scenarios allowed you to find out information in an especially cool way, or add dimension to your character, in exchange for spends. For example, in one of the Stunning Eldritch Tales adventures you can specify that you already know one of the key characters—but it’s up to the player to squeeze a concrete advantage out of that. It turns out that players want a bigger, clearer gain when they spend points. So in more recent scenarios you’ll see us moving more toward palpable game advantages, like bonuses to general ability tests, or being able to avoid a clearly undesirable plot outcome.

You’ll see this thought carried through into the simplified equivalent of investigative spends that appears in GUMSHOE One-2-One. In that iteration of the game they become scarcer resources, and must always deliver something strong when they are spent.

Roleplaying scenarios in general sometimes lapse into extended passages of background information that might be of interest to the GM while reading but has no likely way to come up in play, and will thus remain undiscovered by the players. GMs need enough information to run the scenario and understand the logic behind the actions of the supporting characters they’ll be playing, in case players hit them with unexpected questions. But when writing it can be tempting to just start spinning out details of the fictional world without finding a way to make them pay off at the table. Even in the early years I think we mostly caught and fixed such passages during the development phase. The Great Pelgrane who sits atop our London eyrie remains vigilant against them today, snapping up transgressors of this principle with his piercing beak.

Another factor I’ve been more cognizant of over the years: the possibility that GMs will over-interpret a throwaway line of in-world description. For example the tradecraft Ordo Veritatis agents use to conceal their identities isn’t mean to become an obstacle during play. Instead the GM should describe it as challenging without making it a genuine uninteresting additional hassle. But if I don’t come out and say this while writing, I can easily mislead the GM into making a big deal of what I regard as an atmospheric element. The general fix for issues like this is to break more readily from fictional world voice to speak directly, designer-to-GM about what I hope to help you make happen at the gaming table.

Other than that the changes to scenarios mostly come from the emulation of the new genres we take on. Ashen Stars required a look at the way investigation works in shows like “Star Trek” and “Firefly.” Likewise with Night’s Black Agents and contemporary spy thrillers like the Bourne Trilo… er, Quadrilogy I guess it now is.

With Cthulhu Confidential and The Yellow King on the horizon, we’ll continue to refine GUMSHOE for particular experiences. I look forward to seeing what our scenarios will look like in another ten years’ time.
