🐕 The Dog That Didn't Bark
🕵️ A Sherlock Holmes tool — The consulting detective himself
In Silver Blaze the whole case turns on a silence: the stable dog that did nothing in the night-time. This trainer deals you scene after scene in which the deciding fact is missing rather than present. Among the vivid details on offer, exactly one is an absence that matters — the letter never answered, the alarm that never rang, the mud that is not on the boots. Find it, hear the reasoning, and build the habit of asking every account: what did this story promise me that never appeared?
✅ Free to use — no account, nothing to configure.
What it does
The curious incident, endlessly
AI-conjured mysteries where the key evidence is what is absent — a new scene every round.
One silence among the noise
Four details: three vivid and present and beside the point, one absence that decides the case.
The reasoning, spelled out
Every round ends with the expectation → silence → inference chain, in Holmes's own register.
