Traditional Tasks Get Minimum Effort
It happens in every classroom:
- A reading or writing task lands on the desk
- Students skim, copy, or switch off entirely
- The work that comes back is shallow
- No real thinking has taken place




Hand your students a case file instead of a worksheet. They'll read deeper, write sharper, and think like investigators.

The documents are now available to download. Click the download buttons to save each piece of evidence.
The Detective Experience is an investigation-based learning programme where students work as detectives on immersive cases set in the fictional town of Anchors Bay. Every case demands close reading, evidence analysis, and written argument. Students don't realise they're building literacy skills because they're too busy solving the case.
It happens in every classroom:
TDE changes the dynamic completely:
Every investigation arrives ready to run: digital facilitator guide, structured student tasks, evidence packs, model answers, and extension activities. Open the case and go.
One lesson, a week-long sequence, or a full cross-curricular project. Each case scales to fit your timetable and curriculum goals. You decide the format, TDE provides the content.
Witness statements, forensic reports, CCTV logs, suspect profiles. Students engage with complex texts because the investigation depends on it. Every document sharpens comprehension, inference, and source evaluation.
TDE runs across elementary and secondary settings in English, Science, Social Studies, PSHE, and beyond. The reading, writing, and thinking skills students develop through investigation carry into every part of the curriculum.
Every case demands close reading, persuasive writing, critical thinking, and evidence evaluation. Students aren't filling in blanks or answering comprehension questions. They're analysing evidence, constructing arguments, and defending their conclusions. The literacy is real because the investigation is real.
One whole-school licence covers every case in the library, every teacher in your school, and every new release while your membership is active.
Every case follows six stages that mirror a real criminal investigation. Click each stage to see what students do and the skills they build along the way.
Students receive their case file and are dropped into the world of Anchors Bay. A crime has been committed, and they've been assigned to investigate. Suspense and intrigue grab attention from the first moment.
Every TDE case builds six core skills that students carry into every subject, every assignment, and every year level that follows.
Evidence packs, witness statements, reports
Students read complex, multi-format texts because the case depends on it. They extract key details, identify inconsistencies, and draw meaning from challenging material.
Case theories, suspect arguments, final reports
Building a case requires structured, evidence-based writing. Students learn to construct arguments, support claims with specific evidence, and write with clarity and conviction.
Theory construction, suspect evaluation, peer debate
Students weigh competing explanations, challenge assumptions, and reason through ambiguity. The case rarely has one obvious answer, and that's the point.
Witness reliability, document analysis, bias detection
Not every witness tells the truth. Not every document is reliable. Students learn to assess credibility, detect bias, and distinguish strong evidence from weak.
Team investigation, shared analysis, group decisions
Cases are designed for teams. Students divide responsibilities, share findings, debate theories, and reach consensus. The investigation only succeeds when everyone contributes.
Case presentations, peer questioning, oral defence
Students present their conclusions, field tough questions, and defend their reasoning under pressure. They learn to articulate complex ideas clearly and hold their position.
The skills students develop through TDE are not case-specific. They carry directly into curriculum work across every subject area.
Reading, writing, comprehension
Stronger close reading, more structured persuasive writing, and deeper comprehension from day one.
Evidence, hypothesis, analysis
The evidence evaluation and hypothesis-testing habits built in TDE mirror the scientific method directly.
Perspective, bias, decision-making
Assessing witness reliability and detecting bias prepares students for analysing historical sources and real-world issues.
These aren't abstract skills taught in isolation. They're built through investigation and applied across the entire curriculum. That's the difference.
TDE doesn't just engage students for the duration of a case. It builds habits of reading, writing, and thinking that stay with them long after the investigation closes.
A real case with real stakes captures attention. Students are invested from the first briefing because they want to know what happened.
As they investigate, students read closely, write persuasively, evaluate sources, and construct arguments. The skills develop because the case demands them.
The reveal stage makes thinking visible. Students see where their reasoning was strong, where they were misled, and what skills made the difference.
Close reading, structured writing, evidence evaluation, and critical thinking become second nature. Students carry these skills into every subject and every assignment.
There are no reminders to "read carefully" or "support your answer with evidence." The investigation creates those demands naturally. Students read because they need information. They write because they're building a case. The effort is self-directed.
Teachers report that students approach reading tasks differently after TDE. They question sources, look for evidence before forming opinions, and structure their writing with more clarity. The investigation trains them to think this way by default.
TDE gives students a reason to develop reading, writing, and critical thinking skills through something they genuinely care about. Once those habits are formed, they don't disappear when the case closes. They become how students work.
Schools around the world are using TDE to drive reading, writing, and critical thinking through investigation, from elementary through secondary.
When John Therry Catholic College ran TDE, library traffic increased by 60%. Students who had investigated forensic evidence during the case came back independently to read more about the subject. The investigation didn't just engage them for a week. It changed how they used the library and how they approached reading on their own.
Educators across schools describe the impact of TDE on student inquiry, engagement, and the transfer to independent thinking.
"The students didn't just read the evidence documents. They interrogated them. They questioned reliability, cross-referenced details, built arguments. I've never seen that level of critical engagement from a single programme. They were doing inquiry and they didn't even know it."
"We saw a 60% increase in library traffic as students pursued independent inquiry sparked by TDE investigations. The library became the headquarters for investigation. It transformed from a quiet reading room into the hub of inquiry for the entire school."
"What impressed me most was the transfer. After running TDE, students approached their next research project differently. They were questioning sources, looking for corroborating evidence, building structured arguments. The inquiry habits stuck."
"I've tried every reading intervention on the market. TDE is different because it doesn't just get students reading. It gets them thinking like investigators. They question, they infer, they evaluate. These are the inquiry skills we've been trying to build for years."
