The Controluce series · Alessandro Cascio
Read.Test.Teach.
Controluce is a book series on private security and investigations in Italy, written by someone who has worked in the field for forty years. Each non-fiction Fascicolo is a three-part system: the book to understand, the Workbook to test the skills you have acquired, and the teacher’s guide for those who take it into the classroom. The books are in Italian.
How it works
One book, one workbook, one guide.
You read the book. You fill in the workbook. The guide is for those who teach. Three different tools, designed to work together.
Read
The book
The reference text: the rules explained, real cases, the working method. It is the foundation of everything, and it can also be read on its own.
Test
The Workbook
The hands-on workbook for testing the skills acquired with the book. Twelve modules, to work through pen in hand:
- the essentials on one page and the law in plain words
- true or false and closed-answer questions
- practical cases to solve in writing, with open answers
- the mistake that costs dearly
- the final test, with annotated answers
Teach
