Running Through London in Sherlock Holmes: The Art of Deduction
The game drops you into Victorian London as Sherlock Holmes, and you spend most of your time examining crime scenes, collecting clues, and building a deduction board. That's the loop. It's straightforward once you figure out how the evidence system actually works under the hood. When you enter a scene, there's always a cluster of glowing points. Some are red herrings, some are genuine. The game doesn't care how many you collect. What matters is whether you put them together in the right sequence on the deduction board. I spent about six hours on my first playthrough just grinding through every clue because I thought I needed them all. I didn't. You only need the critical path evidence. The rest is filler that doesn't affect the outcome.
Sherlock Holmes The Art Of Deduction and How the Deduction System Actually Works
The core mechanic is combining two pieces of evidence to unlock a new insight. You open the journal, select two items, and if they connect logically, you get a deduction. The game gives you feedback, but it's not always immediately clear what the correct combination is. You'll hit dead ends. A lot of them. Here's the thing most players miss: the deduction system has a hidden dependency chain. Some clues only become available after you've solved a prior deduction, even if that clue was visible in the environment from the start. I ran into this during the Serjeant Barton case. There was a broken pocket watch sitting on a desk that I'd been examining since hour one, but it wouldn't let me combine it with anything. I came back to it four hours later after solving a completely unrelated deduction, and suddenly it clicked. The watch's position on the board unlocked a new connection that revealed the timeline of the murder. The workaround I ended up using consistently was to revisit every previously examined location after each major deduction. New evidence spawns or becomes combinable after story beats progress. The game updates the scene state, but it doesn't tell you that explicitly. You just have to know to go back and check again.
What Most Players Get Wrong About the Gameplay
The first big mistake people make is treating the game like an adventure title where they need to talk to every NPC and examine every surface. You don't. The game is structured around a linear mystery with branching deduction paths, not open exploration. Spend more than twenty minutes in any given scene and you're wasting time. Look at the scene, grab the glowing markers, move on. Another common pitfall is the inventory. You'll accumulate a lot of items, and the game never forces you to discard anything. Your inventory can hold dozens of objects by the end of Act 1. This isn't a problem for gameplay, but it slows down your UI navigation significantly. I found that keeping only active evidence and junking everything else early on made the journal much faster to scroll through during deduction sequences. The combat sections are worth mentioning even though they're barely related to the main mechanic. They use a stamina-based button-mashing system with light and heavy attacks. The difficulty spikes sharply in the second act, and there's no way to opt out. I went through three attempts on the final boss fight before I figured out that pacing your heavy attacks between enemy wind-ups matters more than raw damage output. The boss telegraphs its moves clearly if you actually watch the animation rather than mashing buttons.

The Deduction Board Explained
The journal's deduction system is the central interface. You have a board where you place evidence nodes and draw connections between them. When you combine the right pieces, new nodes appear and the board expands. The visual layout is basically a flowchart of your reasoning. There are two types of deductions: narrative deductions that advance the plot, and environmental deductions that reveal hidden information about a scene. The environmental ones are where most of the puzzle depth lives. A lot of players skip these because the narrative ones feel more important, but the environmental deductions often give you clues that are necessary for later story beats. If you're stuck on a particular deduction, check whether you missed an environmental one in an earlier act. I also discovered that the game sometimes places multiple valid combination paths to the same conclusion. During the case involving Lady Eva Blackwell, there were at least two different evidence pairs that could lead to the same deduction about her whereabouts. The game accepts either path. This isn't always consistent though. Some sections lock you into a single correct combination, and trying an alternative will just give you a generic error message. There's no in-game indicator telling you whether multiple paths are available, so you just have to learn which cases allow flexibility and which don't through trial and error.
Performance and Known Issues
The game has several technical issues that aren't going to be fixed in any meaningful way at this point. Frame pacing on PC can be inconsistent, particularly during cutscenes where the engine stutters noticeably. I've seen reports of save corruption after Act 3, though I personally only experienced it on a second playthrough where I loaded a backup from the beginning of the chapter. Always keep a recent save outside of auto-save slots. There's also a known issue where certain deductions fail to trigger if you approach a scene from a specific angle. I ran into this during a later investigation where the game wouldn't register a clue I'd already collected because I was standing too close to a wall. Moving back three meters and re-examining the area fixed it. The collision detection in the game is imperfect, and the point-of-interest system has trouble registering objects when you're clipping through geometry.
Should You Play It
If you're looking for a straightforward mystery game with minimal combat friction and a tight story, this delivers. The narrative is solid, the voice acting is competent, and the deduction mechanics are satisfying once you internalize the pattern. But if you want a deep mystery simulation where your choices fundamentally change outcomes, this isn't it. The game has a single solution path per case. Your deductions lead to the same conclusions regardless of which combination route you take. The sequel, Sherlock Holmes: The Awakened, improves on most of these systems. It has better pacing, fewer empty exploration segments, and a more intuitive deduction UI. If you're deciding between the two, starting with the sequel might be the better use of your time, though the first game is still worth playing for the standalone cases and the origin story it establishes for the character.
