Eight chapters, sixteen clues
A detective story that only moves when you understand it.
No vocabulary drills. The Spanish is the puzzle — read the scene, work out what someone actually said, and the case advances.
Watch
Every chapter opens with a narrated film — illustrated, scored, and spoken by Argentine voices. Twenty-nine scenes in all.
Solve
Two clues per chapter, sixteen in total. Type your answer or pick one. Every clue has a hint, a stronger hint, and an explanation.
Collect
Each solved chapter yields one letter of evidence. Assemble all seven and you have the password that ends the case.
The trail
Eight provinces. Each one teaches you something.
The route is the syllabus. You don't study the past tense — you need it to work out which delivery the clockmaker meant.

Real Spanish, real places
The Spanish Argentines actually speak.
Everyone you meet uses vos — vos sos, tenés, vení, subí. A taxi driver in the rain, a guide at Iguazú, a singer in a Salta peña, a clockmaker in the sierras. Each chapter carries a culture note and the vocabulary you needed to get through it.
Get a clue wrong and nothing punishes you — you get a hint, then a stronger one, then the answer with an explanation. The case waits.
Best on Wi-Fi — about 40 MB of film across the eight chapters, loaded a chapter at a time.
