🎓 Think Like Sherlock — The Campaign
🕵️ A Sherlock Holmes tool — The consulting detective himself
Not a listicle about Sherlock Holmes — a training campaign. Seven cases, taken in order, each drilling one faculty of the method: the Eye (observation), the Attic (memory), the Leap (deduction), the Razor (elimination), the Pattern (induction), the Shield (defense against manipulation), and the Method Entire. Every case sets concrete missions inside the site's tools and games, every mission pays XP toward your rank — Constable to Consulting Detective — and you measure yourself before and after: the same six-axis self-assessment at enrollment and at graduation, so the change in how you see the world is not a feeling but a number. Optional Holmes-graded examinations score each case out of 100.
✅ Free to use — no account, nothing to configure.
What it does
Seven cases, one method
Observation → memory → deduction → elimination → induction → defense → the method entire. Each unlocks the next.
Missions, not readings
Every case sends you into real tools and games with a measurable target — scores to beat, drills to pass, artifacts to produce.
XP, ranks, and receipts
Missions pay XP; examinations pay more. Your rank climbs from Constable to Consulting Detective, saved in this browser.
Measure the upgrade
A six-axis self-assessment at the start and again at the end — see exactly where the campaign moved you.
