Well, it happens that today's free Packt book is on a subject that I have some familiarity with, so, following the "rules," (self-imposed, could end at any time) I "have" to post it. I was a "Forsensic Files" TV junkie, and digital forensics was frequently a part of investigation of crimes.
Practical Digital Forensics. Again, it's free.

Well, this post is embarrassingly short, so I'll add some filler.
If I was going to be a forensics investigator it would be in handwriting analysis. I think that that is so cool.
Oh, don't forget that Packt's "day" doesn't correspond to ours (well, at least anywhere near the ET in the U.S). At this moment, it ends after 21:38:04.
