Students work in investigative teams to analyze staff profiles, forensic photographs, an intercepted phone call, and social media profiles eliminating suspects at each stage until they uncover a final two-culprit twist that nobody sees coming.

What makes this different:

• Real language in context — modal verbs are not practiced in isolation. Students use simple and perfect modals because the task genuinely requires it.
• Watertight logic — every clue has been carefully designed so that exactly the right suspects are eliminated at each phase. No ambiguity, no misleading information.
• Built-in differentiation — a modal verb reference bank and partial transcript scaffold support weaker students without making the activity easier for stronger ones.
• Two formats included — a digital version for whole-class use and a printed version with a checkpoint system where teams only advance when they get the task right.
• Complete teacher support — a full teacher guide includes phase-by-phase answer keys, checkpoint guidance, common errors to watch for, and a full audio transcript.
• Four evidence types — written profiles, AI-generated forensic photographs, audio intercept, and fictional social media profiles keep engagement high across sessions.

What's included:

• 22-slide presentation (PDF and link to digital version ready to display)
• Student investigation logs for all 4 phases
• Phase 3 audio file (intercepted phone call)
• Teacher guide with complete answer keys
• Printable version of crime scenes
• Printable version of social media profiles

Target level: B2+ Sessions: 2 × 50 minutes Group size: 3–4 students per team
