Real pages from the case file · 17 pages in the PDF

Lyon Criminal Investigation Unit. The body of Dr Viktor Stein, geneticist, has been found in his underground laboratory, locked from the inside. The pathologist notes two punctures that are not the same age, and that is where the case gets difficult: the time of death is not the time of the act that caused it. Five people close to him had a motive, access or the expertise. The most compromised is not necessarily the killer.

What's included

  • ✓The briefing of 12 March: a geneticist dead in a laboratory that locks itself, five people of interest
  • ✓Ten exhibits to print: autopsy, interviews, an encrypted notebook, toxicology, notes, emails, a newspaper, a plan, contracts, an access log
  • ✓Your working sheets: the two punctures and the true window, the table of the five, the conclusions report
  • ✓Four levels of hints online, from a simple reminder to an intermediate conclusion
  • ✓One week of portal access, counted from your first opening, not from the purchase
  • ✓The full solution online, which opens once you have named the killer

The solution is not in the PDF: it lives on a portal that your code opens, and nobody can stumble on it while leafing through. Everything turns on time: date the two punctures, then reread the access log with the right window.
