Professional Investigator's Manual

This is better than any other book of its kind. Very intelligent writer. Super slow reading. Tedious. Drags on and on. Overkill. That being said, there are so many bad books of this genre out there, this is the best I’ve seen.

This is an excellent study source for preparing for the PCI. This particular guide material is well layout with key points defined. I would recommend this book to anyone studying for the PCI Exam.

Still working on it

I like how this manual breaks down the investigation process. I use this to study for thePCI exam

Perfect for study for professional certification and daily use

Very well made book. One of the best ones in investigation I ever read

Good read!
