One of the things I talked about in The Art of the Key is the conceptual organization of material from the general to the specific: What the PCs immediately see. What they might see. What they can investigate. What they see when they investigate X. This organization, in turn, naturally mimics the way in which the game space is explored during actual play. (Which means that the basic conceptual structure is useful whether you’re keying a location or improvising on the fly.)
I’ve recently realized that there is a specific elaboration upon this general structure that (a) I’ve been using in play for several years without really consciously thinking about it, and which (b) has proven to be very effective. I’m now referring to it as a Matryoshka Search.
Let’s say that PCs are exploring the bedroom of a serial killer. There’s a hidden trap door in the floor leading down to the killer’s mystic butchering chamber. The basic way of handling this scenario looks like this:
Player: There’s gotta be more here. I search the room.
GM: Give me a Search check.
Player: (rolls dice) 25
GM: You find a secret trap door in the floor.
That obviously works just fine. But what I’ll frequently end up doing instead is something like this:
Player: There’s gotta be more here. I search the room.
GM: Give me a Search check.
Player: (rolls dice) 25
GM: There are scuff marks on the floor around the legs of the bed.
Player: As if the bed had been moved back and forth a lot?
GM: Yeah.
Player: I shove the bed to one side and take a look.
GM: You find a secret trap door in the floor.
Instead of immediately discovering the item of interest, the character instead discovers an indicator pointing in the direction of the item of interest. The advantage is that it allows (and even requires) the player to receive information and then draw a conclusion. It’s a subtle distinction, but the result increases the player’s engagement and reduces the feeling that the GM is just handing them whatever information he feels like. I call it the Matryoshka search technique because it turns the interaction into a nested doll: One investigation “opens” new information, which can then be opened by another investigation in turn.
We could also look at this through the lens of the Art of Rulings: The GM is setting an initial threshold for player expertise activating character expertise which is fairly low. (All the player needs to do is say that they want to make a Search check.) But once the character’s expertise has given some sort of result, the GM hits the pause button, turns the interaction back to the player, and basically raises the required threshold. (“Your original declaration has taken you this far, but now I need more information.”) This can make the technique a good way of compromising between players who prefer a very low threshold of player expertise and GMs who want their players to engage more directly with the game world. It’s a naturalistic way of asking, “How are you doing that?” while still moving the action forward.
The Matryoshka technique works even when the indicator really only points at one possible conclusion, as it does in the example above. (Although even in the case of the bed being frequently moved there’s still the question of WHY the bed is moving.) But it can be even more effective if there are multiple explanations possible, requiring additional inquiry and thought before firm conclusions can be reached. As a very simple example, the GM might say, “Taking a closer look at the floor, you can see through the dust and grime clear indications of square-shaped seams.” Is it a pit trap? Is it a pedestal that rises up? Do the seams release poison gas or a force cage projected from below? The player is going to have to figure it out.
This technique is particularly valuable if you’re running the GUMSHOE system: Because every skill use in GUMSHOE is guaranteed to succeed, it can be very easy for investigation actions in the system to feel like “laundry lists” with the player simply naming the skills they want to use and then the GM handing them dollops of information. Matryoshka nesting of information can prevent the automatic successes from becoming lifeless.

I have occasionally run into individual players who do this. (Sometimes for legitimate reasons.) The most common variant is, “I set up a safe house and hole up.” The second most common variant is, “I want to be a special snowflake and go off by myself.”
